Mugello did not provide any sunshince for the highly anticipated second date between Andrea Dovizioso and the Aprilia RS-GP.
The two days on the Tuscan track were characterised throughout by rain, sometimes so light that the track was not entirely wet, and sometimes so heavy that it would have determined “red flag” conditions, had it been a race weekend.
Andrea Dovizioso
It was obviously impossible to complete the planned work schedule, although Andrea was able to try the changes to the RS-GP’s ergonomics, agreed on after the first test in April.
In spite of the rain, the laps on the track and the work in the garage were an important step of growth for Andrea to get better acquainted with the bike and the team. Andrea’s final numbers were 23 laps on Tuesday and 22 on Wednesday for the two days at Mugello.
Specifically to pick up on the work begun a month ago in Jerez in better conditions, Aprilia Racing and Andrea Dovizioso are assessing the possibility of another test to be held during the month of June.
Andrea Dovizioso
“I was very happy to get back on the track with Aprilia, especially here in Mugello. It is a special circuit. The emotion I feel lapping on this track is unique. We weren’t lucky with the weather, but we still tried to exploit these two days of testing. The grip was certainly not ideal for pushing hard, so we focused on understanding and improving the way the RS-GP performs in these conditions. At the end of the previous test, I did not express any definitive opinions because it was just an initial contact, and I think it would be wrong to do so now after two days of rain. I clearly have some ideas, but I think it would be ideal to have another chance to get to know the Aprilia better. I am very happy about the interest generated by my return to a MotoGP bike but, as I have already said, I do not have any long-term plans. I’m having fun, I am relaxed and I’ll evaluate my decisions one step at a time.”
Andrea Dovizioso
Romano Albesiano – Aprilia Racing Technical Director
“Even with the adverse weather, these were two important days. In any case, we tested the RS-GP in the wet for the first time and the indications we had from an expert rider like Andrea are extremely valuable. And, I must say that Andrea lapped rather well in these conditions, with rather interesting times. There is also an aspect that is less connected to pure performance and more to reciprocally getting to know one another that obviously improves with every date. The two days in Mugello were a chance to learn how to get better acquainted and work well together.”
Aleix Espargaró, Lorenzo Savadori and Bradley Smith have been named as the Aprilia Racing riders for the 2021 MotoGP World Championship season. Aprilia have stated that they will decide whether Savadori or Smith get the primary role in the second seat after the conclusion of winter testing. However, Savadori is named in the 2021 provisional MotoGP entry list.
The forced loss of Andrea Iannone, and above all, the vast amount of time his ordeal took, severely damaged Aprilia Racing, whose only “fault” was remaining loyal to their rider and rightfully trusting in reasonable times for the conclusion of the proceedings.
Over the last few weeks, the names of several riders have been associated with Aprilia Racing, as always happens in the negotiating phase. Some of the possibilities evaluated did not come to fruition independently of Aprilia Racing’s desires, so between the situations that were actually feasible and the possibility of continuing with the three riders who rode the RS-GP this season, the latter was chosen.
Given the clear growth of the RS-GP, which was improved in every area and continued to improve significantly in the final part of the season, this will provide continuity to the project for the upcoming season, which will be crucial in preparing for the subsequent five-year period, during which Aprilia intends to put more bikes on the track and implement a rider search and assessment policy.
Massimo Rivola – Aprilia Racing CEO
“It’s no secret that we offered three young riders an opportunity because we felt that our project could be very interesting for talented young riders, but they did not yet feel ready for the leap and, at the same time, the teams that have already signed them for the 2021 season preferred to keep them. We respectfully acknowledge their decision. We prefer to continue with our riders, rather than choosing solutions that are still open but about which we are not entirely convinced. Even in the difficult conditions of this season, particularly penalising for a fledgling project, the bike improved greatly and significantly reduced the gaps both in the races and in practice on basically all the circuits. Aleix finished on a high note and, even in the race yesterday, was lapping with the same times as the leaders. Lorenzo has also shown significant progress in just three races and we know that we can count on Bradley’s professionalism and experience. Aleix will obviously be our top rider. The roles of second rider and test rider will be decided at the end of the winter test schedule.”
Lorenzo Savadori will début in MotoGP astride the Aprilia RS-GP in the Grand Prix of Europe, scheduled to be held in Valencia from 6 through 8 November.
Lorenzo will also sub for Bradley Smith as Aprilia Racing Team Gresini rider in the following rounds which will close out the 2020 MotoGP season, namely the Comunitat Valenciana GP on 15 November, also on the Ricardo Tormo circuit in Valencia, and the GP of Portugal in Portimão on 22 November.
Lorenzo Savadori
“To say I’m happy would be an understatement and I wish to thank Aprilia Racing straight away for this great opportunity. I will be arriving prepared for the event, thanks both to the work done during the tests on the RS-GP and to the CIV season that just ended. It was a challenging Championship that demanded top form and maximum concentration from me. Now I need to reorganise my thoughts, glean from the kilometres I’ve ridden astride the RS-GP and make sure I’m ready and focused for the first practice session.”
Lorenzo Savadori
Lorenzo Savadori is the newly crowned Italian SBK Champion after dominating the 2020 CIV premier category with six wins and two second-place finishes in the eight races held astride his Aprilia RSV4 managed by Nuova M2 Racing team. This extraordinary performance, achieved in a highly competitive championship against rivals with multiple titles, combined with his efforts as MotoGP tester pursued from the beginning of the year, led to his début in the premier class of worldwide motorcycle racing.
Massimo Rivola – Aprilia Racing CEO
“First and foremost, I wish to thank Bradley for his efforts this season. He took one the unexpected role of factory rider with great dignity and outstanding performance, and his contribution was extremely valuable. Now we are excitedly awaiting Lorenzo’s début. This promotion is certainly a reward for his great season as a CIV rider, dominating the Superbike category. But it is also a step of growth for a rider who will be a tester for our RS-GP in 2021 as well. Riding our fledgling project in the race as well will certainly be a step forward for Lorenzo and, therefore, for all of Aprilia Racing.”
Lorenzo Savadori won the STK1000 Championship in 2015
Lorenzo Savadori was born in Cesena in 1993, was Italian and European 125 GP Champion with Aprilia in 2008. In the same season, he made his début in the 125 World Championship with three wild cards. In 2007 he was runner up in the Red Bull Rookies Cup development program. In 2009 he raced in the 125 World Championship.
In 2011 he made his début in the Superstock 1000 championship where he was runner-up champion in 2014.
In 2015 rode the new Aprilia RSV4 RF in its Superstock début and it was a triumph: he took 4 wins, 7 podiums and 3 pole positions which resulted in him winning the Superstock 1000 FIM Cup championship, giving Aprilia the Manufacturers Title.
In 2016, 2017 and 2018, Lorenzo had already competed in the in the WorldSBK Championship, also on the Aprilia RSV4. In 2019, he finished as runner-up Superbike champion in Campionato Italiano Velocità.
In 2020 he became an Aprilia test rider and dominated the CIV Superbike season with six wins out of eight races, earning the Italian Championship title astride the new Aprilia RSV4 Factory.
We’re told the supersport market is dead, and yes, sales show a monumental decline in this class over the last two decades, but these exciting, dedicated track bikes are simply that, race bikes, with high revving engines and radical riding positions that can be hard work for everyday use on the road. But despite its supersport styling, Aprilia’s RS660 wasn’t designed for the track; this is a comfortable and unintimidating road bike with a typically Aprilia sporting edge.
2021 Aprilia RS660 Review
The RS660 is powered by a parallel twin with a 270-degree crank, which is essentially the front half of the RSV4. But although the RS660 is an ‘entry-level’ bike for Aprilia, and is designed for a young and inexperienced audience, it’s neither bland nor dull – the opposite in fact – and sports even more rider aids than Aprilia’s flagship superbike RSV4. Cornering ABS, multiple track and rider modes, traction and wheel control, an up-and-down quick-shifter, even cruise control make for a world class array of electronic aids on a 100 horsepower sub $20,000 bike.
Does it handle?
It has a short wheelbase at just 169 kg dry or 183 kg with fuel it is light, there’s adjustable suspension, a wide 180-section rear hoop, and that purple and red colour scheme is somewhat reminiscent of the legendary two-stroke RS250. If you don’t know what that is ask a grown up.
The seat has some padding, the bars are relatively high and wide, the ergonomics are comfortable and the pegs are relatively low. Not what I was expecting. The parallel twin is a road bike first and foremost, but one that can also be taken to the track.
2021 Aprilia RS660 Review
The steering is light, which is exaggerated by the wide bars. It’s fun, yet stable, giving you the option to steer into the corner, or hang off the inside, knee on the deck. It is user friendly and welcoming, you just jump on and ride, safe in the knowledge you have excellent rider aids at hand, should you get in a little too hot.
Kayaba 43 mm forks are fully adjustable and were flawless on the road test. The rear unit is also adjustable (aside from compression), and even at a sharp road pace is hard to fault. Arguably it doesn’t have the plush ‘top-level’ feel of quality Öhlins units or similar and I’m sure you’ll need a little more support on track with race tyres. But, overall, it’s an easy handling road bike. I’m sure a more purpose track version will be coming soon……
Standard radial Brembo stoppers with braided lines and radial master cylinder are more than up for the job, especially when you consider the bike’s lack of weight. When stopping 183 kg from a top speed of around 230 km/h, you don’t need the most expensive race-spec Brembo stoppers. The feel is excellent, even the back brake, and the cornering ABS isn’t intrusive on the road.
Interestingly, you have three levels of ABS. The most intrusive is cornering ABS front and rear, mode two is similar but less intrusive, and mode one is conventional ABS on the front, not cornering ABS and no ABS on the rear, which in experienced hands with the standard slipper clutch allows you back into corners for fun.
2021 Aprilia RS660 Review
Is it quick?
What Aprilia has done is essentially use their RSV4 as a base, chopping the V4 engine in half to produce a parallel twin. The bore size is the same as the RSV4 1100, but the stroke is up to 63.93 mm, not the 52.3 mm of the V-Four.
The twin-cylinder DOHC engine produces a respectable 100 horsepower at 10,500 rpm and 67 Nm at 8500 rpm, that is more torque than a Yamaha R6 or Honda CBR650R. The little twin will bounce off the rev limiter at 11,500 rpm but with a race kit will rev on for another 1000 rpm. But this isn’t a race engine; 80 per cent of the torque is available from as low as 4000rpm, and 90 per cent of the twist is available from 6250rpm.
You don’t simply magically cut the V4 in half. There’s a new clutch, a new intake system, a new cylinder head, new 48 mm throttle bodies… this is an entirely new engine, albeit one that leans on the experience and knowledge gained from the V4. Aprilia has made the engine run smoother, with a new counter-weighted 270-degree crankshaft. The engine is a structural part of the bike, too, the swing-arm bolts directly to the rear of the crankcases.
2021 Aprilia RS660 Review
The 270-degree crank gives the RS660 a distinctive exhaust tone, very much like a slow revving RSV4. It doesn’t sound like a Kawasaki Z650 (with its 180-degree crank), the Aprilia is much smoother. The light, one-piece, 6.2 kg exhaust consists of one silencer per cylinder plus a cat’ exhaust/collector box, which then exits on either side of the rear tyre. The two jutting exhausts not only gives the 660 a rare sound but also a distinguishing symmetrical look. A tickle of the ride-by-wire throttle allows the revs to dart up the full colour TFT digital dash. The revs build fluently, quicker than I was expecting, and for a standard exhaust, the system adds a little spirit to the RS660 experience.
There are five riding modes to opt from: three for the road – Commute, Dynamic and Individual – and two for the track – Challenge and Track Attack. Each mode changes the engine character, feeling and the multiple rider aids, including traction and wheelie control, cornering ABS, engine brake assist, while the-up-and-down quick-shifter which comes as standard is the same in all modes. Again, you can change and personalise each mode if you wish. It’s simple and intuitive, the new switchgear makes it easier than ever.
To start I opted for the commute mode, with the fuelling set to three, the kindest setting. The fuelling was perfect. Aprilia has a world-class fuelling team, throttle response is always perfect, which is particularly impressive for a parallel twin. Again, like the premium RSV4 1100, the quick-shifter is perfect too, both up and down.
2021 Aprilia RS660 Review
As we headed into the Alps it was time to flick from Commute mode to Dynamic, which automatically changes the engine character and response, and lessens the intrusion of rider aids. The response is a little sharper, especially from a closed to an open throttle. It’s not snatchy, the fuelling is again excellent. Power is relatively linear and you can short-shift on the rapid quick-shifter and still make progress.
There’s a little boost around 7500 rpm, and the modest twin loves to rev to the limiter at 11,500 rpm. It’s so entertaining to thrash, tapping up and down the quick-shifter with the clutch redundant, excellent rider aids and cornering ABS on hand if the road surface should unexpectedly change.
Then, for sheer (and immature) amusement, I switched into the Individual mode, which I’d previously pre-set for no traction control, no anti-wheelie, power on the most aggressive mode, engine braking down to one, and ABS set to one, which means only conventional ABS on the front, not cornering ABS and no ABS on the rear.
2021 Aprilia RS660 Review
The RS660 will wheelie in the first two gears with some encouragement from the clutch. It’s a great engine to stir, and thankfully, when you look down at the full colour TFT dash, you’re not doubling the speed limit and facing a jail sentence. The RS660 is reasonably quick, I’d estimate top speed is around 230 km/h, but unlike a RSV4 it’s not scary on the road, dare we say even practical.
The new parallel twin is frugal on fuel. Aprilia quote 4.89l-100km, but on a steady ride in the afternoon I managed 4.15l-100km, which gives a possible tank range (15L tank) of over 321km. Four hours in the saddle wouldn’t be heartbreak either, because the ergonomics are roomy for this type of bike, with pegs lower than the RSV4 and the bars that are wide.
The bodywork is also impressive; the screen is almost a double bubble TT style screen, making it straightforward to get tucked in at speed, and at motorway cruising speeds does a half-decent job of wind protection.
120 km/h equates to around 6000 rpm and, while there are a few vibrations felt from the pegs and a little from the bar ends as the speed and revs increase, it’s nothing unpleasant. Aprilia even offers a tail pack and a tank bag as optional extras, and I’d happily take on some serious miles on the RS660 and even use the cruise control.
2021 Aprilia RS660 Review
Gadgets to keep the youngsters happy
Rider aids aren’t really needed on a 100 horsepower middleweight already furnished with a first-rate chassis and tyres. But you have to remember the young audience which Aprilia is attracting, and for more experienced riders they can to de-activated even on the move.
At your finger tips are multiple rider modes, eight-stage traction control, wheelie control, engine brake assist plus cornering ABS and conventional ABS. Additionally, you have cruise control and an up-and-down quick-shifter. The modes are straightforward to change on the fly, and you can even de-active the traction and wheelie control.
The array of rider aids is impressive, but I favor the thumb and finger traction control toggle switches on the RSV4 Factory. Furthermore, the RS’s rider aids aren’t displayed on the main menu whilst riding. The rider modes are clear but you can’t, for example, glance down and see how much TC you’re running – that info is within a sub-menu.
Got to let a twin sing….
There are the typical accessories from Akrapovic, including a full exhaust. There is also additional software available which means you can flick over to a race shift, and have access to a pit lane limiter. Away from the racetrack, there is a comfortable seat, USB socket, luggage… even a larger fairing and Bluetooth connectivity.
Yep, you could probably tour on it too…
2020 Aprilia RS660 Verdict
I’m impressed with Aprilia’s new RS660. A usable, friendly, road-going sports bike overloaded with rider aids and just about affordable, just. The versatile engine that should not get you into too much difficulty and there is the safety net of top level rider aids.
It sounds great, has character, is eye-catching, and is desirable.
Aprilia has possibly gone a little overboard on the rider aids, and the suspension may need an upgrade for some serious racing/track action – but I’m sure there will be a sportier version in the pipeline soon. I can wait to try it on track. A multitalented, entertaining, attractive bike for the inexperienced and experienced alike – top work Aprilia

Aprilia RS660
After the arrival of the RS660 sportsbike in April 2021, we can expect an off-road Tuareg and Streetfighter versions based on this platform to follow in due course. It is fair to expect that this machine will be pitched into a higher price bracket than most middleweight machines.
Aprilia RS660
The RS 660 offers first-rate technical content, honed from Aprilia’s competition racing experience, made available for street-riding fun. A perfect formula for maximum enjoyment, at a slender wet weight of 183 kilos, featuring a package of APRC electronic rider aids that would be at home even in superior classes.
Aprilia RS660
The main features of the fairings speak typical Aprilia sporting parlance, and are characterized by a triple LED headlight assembly, equipped with perimeter Daytime Running Lights positioned around the two main headlights, making the RS 660 immediately distinguishable in any lighting conditions.
Aprilia RS660
Direction indicators are integrated into the DRL profiles making the front end even more compact. The lighting system is equipped with several features to make riding even safer: thanks to the presence of a twilight sensor, the dipped beams are switched on automatically, while the self-cancelling turn indicators flash in the event of emergency braking. Finally, thanks to the cornering lights function, a pair of additional headlights in the parabolas illuminate the inside of the curve, increasing visibility when taking bends.
Aprilia RS660
The seat-footpeg-handlebar triangulation welcomes riders of all stature, according to Aprilia, offering comfort and spaciousness, with a posture that is neither heavily-loaded onto the handlebars, nor with legs excessively bent due to highly-placed foot-rests.
Aprilia RS660
Aprilia claim that the seat features very comfortable padding and is tapered at the sides to facilitate the resting of the feet on the ground which allows easy manoeuvres from a stationary position. A pillion pad is positioned on the tail while a single-seat tail comes as an optional extra.
Aprilia RS660
The 15-litre capacity petrol tank is designed to enhances the compactness.
Aprilia RS660
In the traditional vein of Aprilia sports models, the RS 660 has also been designed to facilitate the fast, easy removal of any surplus elements when used on the track, such as mirrors, passenger footrests and license plate holders.
Aprilia RS660
The frame and swingarm are both die-cast aluminium, featuring unique characteristics within their class. The chassis dimensions favour agility: thanks to its 1370 mm wheelbase and the 24.1° inclination of the steering head, the RS 660 boasts exceptional handling capabilities, combined with all the precise features and sensations that characterise the front end of classic Noale-produced motorcycles.
Aprilia RS660
The frame is made up of twin lateral beams bolted into the steering head area and, to the rear; the engine is maximized as a load-bearing element and contributes to forming a compact, lightweight yet rigid structure. In order to make the frame even lighter and more essential, the swingarm is pivoted directly into the engine: this is a monobloc element characterized by its considerable length, useful for having optimum traction and asymmetrical arms – a typical technical choice in the history of the Aprilia RS. The particular mounting of the adjustable shock absorber allows for excellent progression even without the insertion of any linkage, thus reducing even more precious weight.
Aprilia RS660
In designing the frame, Aprilia designers paid particular attention to the area of the steering head to ensure the necessary sturdiness for both road and track use, while keeping the turn radius very low to facilitate everyday riding use.
Aprilia RS660
The chassis is completed by an adjustable Kayaba fork with 41 mm upside-down stems and a braking system made up of, a pair of 320 mm diameter steel discs, at the front and a pair of radial mount calipers and a radial master cylinder on the handlebars both manufactured by Brembo.
Aprilia RS660
This is a 660 cc parallel-twin cylinder unit, a highly compact latest-generation engine derived from the 1100 cc front-banked V4, whose line it follows in both concept and measurements and sports a Euro 5 homologation.
Aprilia RS660
This configuration was chosen for its compactness and lightness. An engine with reduced horizontal and lateral dimensions allows great design freedom both for the arrangement of fundamental parts such as the intake and exhaust. As far as the chassis is concerned, the engine also features load-bearing functions, while housing the swingarm to its rear.
Aprilia RS660
The front-leaning configuration affords the rider more comfort, thanks to the greater heat dissipation and leaves the designers plenty of freedom to exploit the space. Furthermore, the engineering lends itself to superior cooling, helped also by the ingenious double-walled fairing system which aims at accelerating the air flows passing through it. With the same objective in mind, long exhaust manifolds were engineered to funnel flows into a single-piece tailpipe with a asymmetrical split outlet, all fully positioned beneath the engine, with the added advantage of superior weight distribution and a lower centre of gravity.
Aprilia RS660
The new Aprilia twin-cylinder is the result of experience gained developing the extremely powerful engine that equips the RSV4 and is therefore based on a background of highly efficient and technical trials: the cylinder head, combustion chambers, ducts, cylinders and pistons all derive from the V4. Likewise, it features an 81 mm bore – as in the 1078 cc V4 – with a 63.9 mm stroke. The decision to take advantage of the V4 technology guarantees top-class performance, while taking into consideration the high piston stroke speeds relative to its displacement size. Naturally, all engine components, including castings and molds, have all been designed and developed from the ground up.
Aprilia RS660
The new engine has the crankcase split horizontally into two pieces with the cylinders integrated into the upper crankcase to reduce overall dimensions to render the structure more robust. The cylinders are offset from the crankshaft to minimize internal friction during piston thrusts.
The hollowed camshafts of the 4-valve-per-cylinder twin-shaft are side chain driven. The mechanically operated oil bath multi disc clutch has a built-in assist and slipper system. Wet sump lubrication involves an oil sump protruding downwards and crafted around the intake port, in order to best gather the lubricant in every type of riding phase, even when the bike is at its maximum inclination or during periods of braking and acceleration.
Aprilia RS660
For a parallel-twin of this displacement, the performance obtained is impressive and comparable to that of a much higher cubic capacity two-cylinder: 100 hp at 10,500 rpm, with an extension capacity that allows the limiter to be moved up to its 11,500 rpm threshold. The maximum 67 Nm torque is offered at 8,500 rpm, with 80% of the torque available from 4,000 rpm, and 90% at 6,250 rpm.
In addition to performance and lightness, another aim of the project was to obtain from the engine the same character and grit typical of V-twin cylinders. To this end, valve timing with connecting rod pins arranged at 270° were chosen. Combustion is thus asymmetrical and offset by 270° to obtain irregular bursts which perform and sound similar to a V-twin. Furthermore, this type of configuration allows, by means of a single countershaft, easy balancing of the alternating forces of first and second order.
Aprilia RS660
The injection system includes a duo of 48 mm-diameter throttle bodies, with intake ducts of varying lengths to optimize delivery at high and medium speeds.
The performance of the new engine is guaranteed by electronics directly loaned from the Aprilia V4, including Ride-by-Wire with multi-mapping, an electronic accelerator, for the subtle management of subtle, yet progressive acceleration, even at low revs and optimal consumption.
The RS 660 is equipped with a six-axis inertial platform which, thanks to the built-in accelerometers and gyroscopes, is able to recognize the condition of the bike with respect to the road; it records and processes inputs deriving from the rider and sends the data to the control unit which intervenes seamlessly in the control parameters.
Aprilia RS660
– ATC: Aprilia Traction Control, adjustable traction control characterized by fine and high-performance intervention logics
– AWC: Aprilia Wheelie Control, adjustable wheelie control system.
– ACC: Aprilia Cruise Control, maintains the set speed without using the throttle control.
– AQS: Aprilia Quick Shift, the electronic gearbox, for high-speed changes without easing off the throttle or without using the clutch, also equipped with a downshift function which allows downshifting without touching the clutch. Thanks to the software offered among the original accessories it is possible to reverse the gearbox for track use without the need to replace components.
– AEB: Aprilia Engine Brake, the adjustable engine brake control system for the deceleration phase.
– AEM: Aprilia Engine Map, various forms of mappings available to change the character and the way engine power is delivered.
Aprilia RS660
The Aprilia RS 660 adopts the advanced multi-map Cornering ABS, to ensure maximum safety on the road, without detracting from its sporting performance. The system, with extremely low weight and dimensions, is able to optimize braking and ABS intervention when cornering, thanks to a special algorithm which constantly monitors various parameters such as lateral acceleration, the pressure exerted on the front brake lever, the angles of lean, pitch and yaw, modulating the action of the brakes for an optimized combination of deceleration and stability.
Aprilia RS660
Aprilia has developed five Riding Modes, not merely to maximize the riding experience in different riding conditions, but also to simplify life on board. Riders are only required to choose which Riding Mode best suits their needs to automatically obtain the best set-up regarding traction control, wheelie control, engine braking, ABS and the other tweakable parameters.
There are three Riding Modes for road use:
Commute, for everyday riding;
Dynamic, for sports riding on the road
Individual, which allows for complete customization of electronic controls.
There are two Riding Modes designed for on-track use:
Challenge, suitable for on-track racing sessions capitalizing on the full potential of the RS 660
Time Attack, a system that allows more adept riders to fully tweak the electronic setup.
Aprilia RS660
Electronic settings are easily managed by a user-friendly four-button control on the left-side electric switch block with quick commands for managing cruise control and traction control.
Aprilia RS660
The full-colour TFT dash boasts exceptional display capabilities for its various parameters. The two selectable Road or Track screens (both with automatic night or day backlighting thanks to the twilight sensor) correspond to the same number of indices represented.
A further option is the Aprilia MIA, Aprilia’s multimedia platform that allows you to connect your smartphone to the bike extending yet more the range of instrumentation functions. The Aprilia MIA system offers a connection protocol that minimizes smartphone battery consumption and includes both the infotainment system for managing voice commands, calls and music via intuitive controls located on the handlebars and the navigation function. It is thus possible – once the destination has been entered into the smartphone – to view the directions directly on the dashboard. The Aprilia MIA app also allows any routes travelled to be recorded and the data, which is gathered by means of the geo-referenced telemetry function, can subsequently be analysed directly in the app.
Aprilia RS660
The Aprilia RS 660 colour range features the funky new Acid Gold, which most suitably reflects the dynamic, young character of the RS 660, enhancing even more the design features of the new Aprilia.
The Aprilia RS 660 is available in two other graphic variations: Lava Red is clearly dominated by colours that hark back to Aprilia’s great sporting heritage. The combination of purple and red is a tribute to the RS 250 in the 1994 Reggiani Replica version, the last true sports bike of the two-stroke engine era, still cherished by motorcyclists and highly sought after by collectors. The second, an Apex Black graphic is characterized by a total black look, which has also long since become part of Aprilia’s sporting history, which help the multiple bright red references to stand out considerably.

After the success achieved by Aprilia RSV4 X, the special version of the supersport bike from Noale, Aprilia has now given the X factor to the Tuono V4.
Aprilia Tuono V4 X
The Aprilia Tuono V4 X is touted as an exclusive “super Tuono” produced in a numbered and limited edition, developed and assembled directly by Aprilia Racing.
Aprilia claim this excluse new Tuono V4 X is capable of lapping Imola in 1m50s with Aprilia rider Lorenzo Savadori, only a couple of seconds away from World Superbike pace around the Italian circuit.
Aleix Espargaró also put it through its paces on the Austrian Red Bull Ring circuit: “The Tuono V4 X is out of this world. I had never tested a high-handlebar bike on the track and I was surprised at the feeling of stability. The engine is insane, but the chassis architecture doesn’t struggle – to the contrary: the riding position and the electronics make it extremely fun. You can ride it cleanly, but you can also drift with it if you want to. It is a pure sportbike with a hooligan side!”
The experience that the Racing Department from Noale has in the top championships contributed to the development of the Aprilia Tuono V4 X with large aero wings in carbon added to the Tuono, clearly derived from the one fitted on the Aprilia RS-GP used in MotoGP. This choice contributes to increasing stability at high speeds and in the critical phases of braking and acceleration.

The goal of making this special Tuono a true high-handlebar racing bike exclusively for track use was achieved in full, thanks to a skilled job of general lightening, which reached the exceptional landmark of 166 kg dry weight on the scales.
All the fairings are in carbon, enhanced by the dedicated “Bol d’Or” graphic, inspired by the Aprilia RSV 1000 R Factory which participated in the 2006 edition of the legendary French endurance race. The fuel tank is the same shape as the original, but it is lighter, while the factory electrical system has been simplified.

Another obviously sports-derived element is the racing panel via which to adjust the main electronic controls of the Tuono V4 X. There are numerous billet aluminium parts that contribute to lowering the weight, such as the clutch lever, the brake lever guard, the engine crankcase guards, the adjustable footpegs and the fuel cap. The Marchesini wheel rims in forged magnesium, shod with racing slicks, provide the added value of handling that is out of reach even for fairing-covered supersport bikes.
The engine is derived from the unit that successfully equips the RSV4 1100 Factory. The Akrapovic exhaust system features titanium collectors and a carbon outlet, while the air filter is a Sprint Filter element, the same unit that Aprilia Racing uses in MotoGP.
Electronic fine-tuning is via a revamped ECU in terms of logic and functions, featuring engine control and vehicle dynamics maps developed by Aprilia Racing. The engine maps are all “full power” and optimised for the racing exhaust system. The engine brake, traction control and anti-wheelie levels are specifically designed for use on the track. It comes standard with two-way quick-shift and the colour TFT instrument cluster reprogrammed with lap time display using the built-in GPS sensor.
The maximum power of the V4 from Noale increases from the 217 HP of the factory unit to the value of 221 HP measured at the crank. Performance that can be fully exploited thanks to a race derived chassis with advanced semi-active Öhlins Smart EC 2.0 suspension system.

The Brembo braking system is also entirely racing, thanks to the use of refined and extremely effective GP4-MS billet aluminium calipers that grip a pair of steel discs with T-Drive technology and are controlled by a 19×16 radial master cylinder, also made in billet aluminium.
Each Aprilia Tuono V4 X unit, available at a price of €34,900 ($56,600 AUD), can already be reserved exclusively online by going to the Aprilia website. Buyers will be able to pick up their unit directly from Aprilia Racing, simultaneously with an exclusive tour of the racing department in Noale, and they will receive a dedicated KYT NX-Race helmet with a graphic inspired by the bike’s graphics.
Tuono V4 X is part of the Factory Works program launched by Aprilia Racing: it takes technology developed in competitive racing and makes it available to those planning to compete at high level in factory derivative championships or to those who want an RSV4 or a Tuono V4 with performance optimised for track use. That means, of course, that the Tuono V4 X will not be able to be used on public roads, legally.
