2021 Ducati Multistrada V4 S (Ducati/)

Ups

• Engine update to spring-operated valves, plus the engine produces more power
• Ducati keeps the electronics coming with new radar system
• Longer service interval
• Ducati-level quality standards

Downs

• No more desmo
• Pricey
• Tired of tech? This model may have too much tech for some

Verdict

The Multistrada continues to meet the demands of a wide range of uses as a heavily revised, tech-laden adventure-tourer, arguably one of the most tech-rich on the market. This Ducati continues its engine’s developments with the drop of desmo for the conventional spring-valve configuration.

2021 Ducati Multistrada V4 S (Ducati/)

Overview

The Ducati Multistrada enters its fourth generation with some major changes for the 2021 model year, namely with the new V4 Granturismo engine. As the flagship adventure-tourer of the Ducati lineup, the Multistrada straddles the line of a dual terrain conqueror and practical, daily sport-tourer. Long-travel suspension, large 19-inch front wheel, and low-end response of the engine aids in the dirt, while new integrated navigation and cornering lights support the tour or daily use. Get your adventure gear ready.

Updates for 2021

Ducati’s flagship adventure-tourer, the Multistrada faces the major change of replacing its well-known desmodromic valve engine with the conventional spring-operated valved V4 Granturismo engine. Other updates include a new double-sided swingarm, shorter wheelbase (now 61.7 inches), new cast-aluminum pyramid-shaped monocoque chassis (with reduced rake and trail), improved subframe, an integrated navigation system, and the industry’s first front and rear radar.

2021 Ducati Multistrada V4 S Sport (Ducati/)

Pricing and Variants

The base Multistrada starts at $19,995, followed by the $24,095 V4 S, and then the V4 S Sport at $26,095. The S variant offers two color options and two different wheels (alloy or spoked—pricing varies depending on color option and wheel type), cornering lights, vehicle hold control, Ducati Skyhook suspension, Ducati Quick Shift, 6.5-inch TFT display with Ducati Connect and full-map navigation system, and a full LED headlight. The V4 S Sport has the same electronics equipment as standard on the S, however, takes the package even further with model-specific livery, Akrapovič exhaust, and carbon front fender.

Powertrain: Engine, Transmission, and Performance

The Multistrada’s headlining change lies in the powerplant, now the V4 Granturismo engine. The Multistrada, and many Ducatis, are well-known for the desmodromic valve timing, but this swap has been made in order to increase the service interval (now 37,250 miles), meet Euro 5 standards, and ultimately be cost effective. Cycle World’s Italian correspondent Bruno dePrato considered this engine change a “very logical choice.”

Ducati claims this engine will produce 170 hp at 10,500 rpm and 92.2 pound-feet at 8,750 rpm.

When Motorcyclist reviewed the V4 S, test rider Adam Child reported: “On the road, fueling is perfect and the V4 is smooth and chilled. In the dedicated Urban riding mode [one of four available], it’s particularly easy and user-friendly to ride, while the new chassis has none of the top-heavy, intimidating feel of some adventure bikes. With the manually operated screen fully upright there is little wind noise, and comfort and ride quality are all-day excellent. In fact, with the BSD system watching your back and the ACC managing and monitoring the traffic in front, the Multi V4 S experience is super relaxed.”

2021 Ducati Multistrada V4 S (Ducati/)

Handling

In terms of handling, Motorcyclist’s Adam Child stated: “The V4 S does not turn like a ponderous, 536-pound adventure bike running on a 19-inch front tire either. Instead, steering is accurate and the bike deceptively nimble, even at speed, while refined cornering ABS and powerful Brembo Stylema front brakes are always on hand if you should dive in a little too hot.”

Brakes

And that transitions into brakes; the V4 stops with Brembo Stylema four-piston calipers with a 320mm (330mm for V4 S and V4 S Sport) front disc, 265mm rear disc, and three-level adjustable cornering ABS. As Adam stated, the brakes are powerful and the cornering ABS is refined.

Fuel Economy and Real-World MPG

Real-world miles-per-gallon figures are currently unavailable.

2021 Ducati Multistrada V4 S (Ducati/)

Ergonomics: Comfort and Utility

“The slim seat allows you to move freely whilst standing up, the high bars are more accommodating, the mirrors don’t get in the way of your arms, and there is lots of peg room for bulky boots,” Adam Child covered. If adjustments are needed to the handlebar position, that adjustment is easily made.

Electronics

When it comes to electronics, the Multi has a long free-flowing list that is worn as a badge of honor. This model’s IMU manages electronics such as the cornering ABS, wheelie control, traction control, and the S version’s cornering lights. The S also sees vehicle hold control, semi-active Ducati Skyhook suspension, and a new left-handlebar joystick to navigate through the menu on the adjustable 6.5-inch TFT unit (5-inch unit on base). A USB connector is also located in the tank compartment. The radar system is one of the newest technological components of the Multistrada and the manufacturer says this allows the use of Adaptive Cruise Control (ACC) and Blind Spot Detection (BSD).

Warranty and Maintenance Coverage

The Multistrada has a two-year unlimited-mileage warranty. Roadside assistance is also available within the Limited Warranty coverage period.

Quality

Ducati’s quality is second to none, and that is reflected in the continuous advancement of the Multistrada. The revised engine, chassis, and integrated tech continue to keep this rig at or very near the top of the adventure-touring segment food chain.

2021 Yamaha WR250F (Yamaha/)

Ups

• Very little clutch use required thanks to well-spaced gear ratios and sufficient roll-on power
• Highly praised stock suspension is softer than the YZ250F, but maintains plenty of bottoming resistance
• Lower gears are useful when navigating technical terrain; second gear in particular has good low-speed capability and can pull longer than expected

Downs

• Engine is difficult to start when in gear
• Adjustments to the ergonomics are preferred
• No stock hand guards

Verdict

When you pull DNA from the top-of-the-class YZ250F, there aren’t many downsides. The WR250F is a capable four-stroke enduro with plenty of power, suspension comfort, and handling capability for great trail riding.

2021 Yamaha WR250F (Yamaha/)

Overview

The 2021 Yamaha WR250F is based on the YZ250F motocross platform, but with an enduro, trail-focused spin. It differs from the YZ-F by including a skid plate, 18-inch rear wheel, 2.2-gallon fuel tank, radiator fan, sealed O-ring chain, enduro meter, steel rear sprocket, different ECU tuning, spark-arrestor-equipped muffler, a headlight, taillight, and kickstand. The combination of these qualities make the quarter-liter WR-F ready and willing to tackle technical trails.

Updates for 2021

Seeing as the 250 enduro received several updates last year, the only changes seen are in its appearance, namely in the form of a blue headlight, blue side number plates, black fork guards, and new graphics.

Pricing and Variants

At $8,599, the WR250F is $300 more than the bLU cRU’s motocrosser of the same displacement.

Powertrain: Engine, Transmission, and Performance

Accelerating the WR250F up and down trails is a 250cc liquid-cooled four-stroke engine. In order to make it suitable for enduro-style riding, it is equipped with a spark-arrestor-type muffler approved by the Forestry Service and unique ECU tuning. Other than that, the engine is the same as its off-road model counterpart, the YZ250FX. In his review on Dirt Rider, Allan Brown noted that the engine runs very well, but its muffler does decrease power output, making it produce 1.7 and 2.9 hp lower than the YZ250FX and YZ250F, respectively. When this enduro-focused machine was put on the in-house Cycle World dyno the result was 36.1 hp at 12,000 rpm and 17.9 pound-feet of torque at 8,100 rpm at the rear wheel.

First and second gears of its six-speed gearbox are particularly useful, Brown writes, because when in second gear throttle response was not lost at crawling speeds and that gear could be used longer than expected. This made for reduced shifting in low-speed, technical trail sections. Fourth, fifth, and sixth have a little more of a noticeable gap on the wide-ratio gearbox. Brown continues, “The 2021 WR250F engine has received a clutch basket update for durability, and the overall performance remains very good. Even though the engine is slightly restricted, clutch fade is almost nonexistent due to good gear ratios and sufficient roll-on power to make abuse of the clutch unnecessary.”

2021 Yamaha WR250F (Yamaha/)

Handling

In short, the WR250F is very comfortable to ride. Its highly praised KYB Speed Sensitive System (SSS) coil-spring-type fork and KYB shock have different valving and spring rates specific for enduro, and have a softer feeling compared to the motocross version, but offer plenty of bottoming resistance. Suspension travel is listed at 12.2 inches (front) and 12.5 inches (rear). Because suspension is softer, Brown reports that it helps the bike “corner well without losing any of the Yamaha trademark stability.”

“Straight off the showroom floor,” he said, “I was able to ride the WR250F to 90 percent of my comfort zone and enjoy every minute of it.”

Brakes

With a front Nissin two-piston caliper, 270mm disc and rear Nissin single-piston caliper, 245mm disc, the WR-F has a 5mm larger rear disc than the YZ250F, which we reported had plenty of stopping power, but its brakes were not as strong as the KTM 250 SX-F’s and Husqvarna FC 250′s Brembos. Still, the WR250F’s Nissin brakes are some of the most progressive on the market.

2021 Yamaha WR250F (Yamaha/)

Fuel Economy and Real-World MPG

While miles per gallon is currently unlisted, the WR250F has a 2.2-gallon fuel tank which is 0.6 gallon larger than the YZ250F motocrosser. This tank size fits within the confines of the bodywork without any unusual protrusions.

Ergonomics: Comfort and Utility

Test rider Brown would prefer a slightly taller seat for the WR250F, but the aftermarket is a great source for those types of modifications. Riders taller than 6 feet would also consider repositioning the handlebar in order to open up the cockpit. Being an enduro machine, we would have also liked to see hand guards come stock.

2021 Yamaha WR250F (Yamaha/)

Electronics

The WR250F features electronics such as an electric starter, headlight, taillight, and an enduro meter that lists two tripmeters, and a race mode that features an average speed display and timer.

Warranty and Maintenance Coverage

The 2021 WR250F comes with a 30-day limited factory warranty.

Quality

With YZ250F DNA coursing through this enduro-tuned 250cc liquid-cooled four-stroke machine, the WR250F provides usable power for technical riding. Many trail riding features are stock, but patrol the aftermarket for a taller seat and hand guards.

2021 Yamaha YZ250FX (Yamaha/)

Ups

• The 250cc four-stroke engine excels at midrange torque and even nips at the heels of 350cc engines
• Free Power Tuner app expands the engine’s versatility
• Well-balanced handling
• Confidence-inspiring suspension

Downs

• Slightly wide compared to competition
• Pocketed seat limits rider maneuverability when sitting
• Has difficulty starting in gear

Verdict

Although it may feel wider and also place the rider further back in its seat, the Yamaha YZ250FX provides a confidence-inspiring suspension package and manageable power for a ride that has the capability to conquer the off-road terrain and its competition.

2021 Yamaha YZ250FX (Yamaha/)

Overview

The Yamaha YZ250FX is the cross-country version of the YZ250F. It is designed with Grand National Cross Country (GNCC) and Hare Scramble races in mind with its six-speed transmission, 2.2-gallon fuel tank, 18-inch rear wheel, and skid plate. The front-intake, rear-exhaust engine design is what Dirt Rider’s Allan Brown says helps make the bike so powerful by 250F standards and contributes to it being a very versatile bike in stock trim.

Updates for 2021

For 2021, the YZ250FX sees no mechanical changes after being heavily updated the year prior. However, it does have an aesthetic change with different number plate and fork guard colors.

Pricing and Variants

The YZ250FX is available in Team Yamaha Blue for an MSRP of $8,499.

Powertrain: Engine, Transmission, and Performance

The FX powers across GNCC-style terrain via its 250cc liquid-cooled four-stroke single-cylinder engine. Test rider Brown said that this engine, which is based on the YZ250F motocross model, has “amazingly broad power and strong durability,” and is even considered to be just about flawless, and it could compete with larger-displacement models such as the Husqvarna FX 350.

When put on our in-house dyno, this single sent 37.8 hp at 12,200 rpm and 18.3 pound-feet of torque at 8,400 rpm to the rear wheel.

One complaint Brown had was that the 250 has difficulty starting, especially in gear, but an upgrade to the battery and keeping the clutch cable snug are two solutions he recommends.

2021 Yamaha YZ250FX (Yamaha/)

Handling

Like the carryover of the engine, the FX plucks the chassis from the F model as well. Brown reports, “The bike’s broad, easy-to-use engine power, good stock suspension settings, and equal balance of stability and cornering make it very easy to get comfortable on.”

Suspension components include a fully adjustable 48mm KYB Speed Sensitive System (SSS) coil-spring-type fork and fully adjustable KYB shock. Suspension is confidence-inspiring with its proficiency at tackling a variety of technical trails and higher-speed terrain, and offers adjustability useful to riders of varying weights and skill levels.

Brakes

Front brake feel from the Nissin two-piston caliper/270mm disc combo is reported to be the most progressive in the market, Brown stated. Some might love that and others might not—that choice comes down to personal preference. A Nissin one-piston caliper and 245mm disc serves as stopping power out back.

2021 Yamaha YZ250FX (Yamaha/)

Fuel Economy and Real-World MPG

Fuel economy numbers are not listed by the manufacturer. Fuel capacity is listed at 2.2 gallons.

Ergonomics: Comfort and Utility

Ergonomics are easily identifiable as Yamaha with a “distinguishable handlebar bend and noticeable pocketed seating position.”

This pocketed seating position is a small complaint Brown has, as it makes the rider slide back easily.

2021 Yamaha YZ250FX (Yamaha/)

Electronics

One of the more notable tech features is the bike’s compatibility with the Yamaha Power Tuner app, which allows the rider to make fueling and ignition timing changes via the smartphone app. Additionally, a handlebar-mounted switch makes preselected engine map swaps a cinch. Powering on the bike is simple with the electric start button.

Warranty and Maintenance Coverage

The FX comes with a 30-day limited factory warranty.

Quality

Some gripes about starting in gear and seating position when riding, but overall our test riders place this bike among the top 250F off-road competition models due to its quality suspension and powerful engine.

2021 Suzuki RM-Z450 (Suzuki/)

Ups

• Cheaper MSRP compared to others in its class
• Excels in cornering
• New MX-Tuner 2.0 offers engine-character adjustability

Downs

• No electric start
• Showa 49mm fork is good, but is held back by the Showa Balance Free Rear Cushion (BFRC) shock
• Heavier than the competition in both feel and actual weight

Verdict

Although it hasn’t seen a major overhaul in recent years, the RM-Z450 is fun to ride and is less expensive than its competitors.

2021 Suzuki RM-Z450 (Mason Owens/)

Overview

The 2021 Suzuki RM-Z450 is the Japanese manufacturer’s one and only 450cc dirt bike. In last year’s Dirt Rider shootout, staff determined that the RM-Z450 was “a good motocross bike in a segment filled with greats.” Noticing the RM-Z’s potential, Dirt Rider improved its power and suspension with aftermarket products in its 2021 Suzuki RM-Z450 Project Bike build in order to make the good bike even better. It’s a bargain at $8,999, which gives some room for improvements, especially if the end user plans on racing. Otherwise, the ideal demographic of the stock trim version are casual trail riders, vets, or even mom/dad going on the occasional weekend trip with their kids.

Updates for 2021

The bodywork’s graphics are new, but no mechanical updates for the 2021 engine. There is, however, engine tunability with the MX-Tuner 2.0 system and smartphone app. This app allows the user to change fuel delivery and ignition system settings.

Pricing and Variants

At $8,999, the full-size Suzuki motocrosser sits well below the $9,399 MSRP of the Kawasaki KX450 and Yamaha YZ450F, which are the lower-priced models in the competitive 450 class.

Powertrain: Engine, Transmission, and Performance

The 449cc liquid-cooled four-stroke engine continues to power the 2021 RM-Z450. As mentioned, the powerplant is tunable with the help of the MX-Tuner 2.0 app where EFI can be adjusted via four preprogrammed maps and custom fuel and ignition maps can be built. Upon review, Dirt Rider observed that the bike is heavier than its competition both in its measured 250-pound weight and hefty feel on the track, the latter of which is attributed to its heavy engine character. Luckily, the MX-Tuner app helps lighten these engine characteristics.

Prior to playing with the engine maps, it ran on our in-house dyno where it produced 50.2 hp at 8,800 rpm and 33.2 pound-feet of torque at 7,600 rpm at the rear wheel. Compared to others of its class this is not a “fire-breather” as test rider Allan Brown put it, but it makes good torque that “is responsive enough off the bottom, and revs just high enough to not feel flat.” Shifting through the five-speed transmission is reported to be smooth and clutch fade is minimal.

2021 Suzuki RM-Z450 (Mason Owens/)

Handling

This 450 motocrosser’s chassis provides excellent cornering, and overall handling is “decent despite its rigid feeling,” Brown says, but this stiffness does result in decreased comfort.

The RM-Z450 features a Showa 49mm twin-chamber coil-spring fork and Showa Balance Free Rear Cushion (BFRC) shock, both of which have remained largely unchanged since they debuted on the bike in 2018. The shock specifically is what needs an update most. Test rider Brown wrote that if this motocrosser is used more casually it will probably do, but more aggressive riding or racing requires modifications. Because the chassis is so rigid, the rider is inclined to soften the suspension. However, softening the settings causes pitching which was resolved when Brown nearly fully closed the compression and rebound adjusters and also set the sag close to 100mm. The resulting high rear-end stance, however, did add some harshness to the fork.

Brakes

Braking is done with a Nissin two-piston caliper and 270mm wave-style front rotor and Nissin single-piston caliper and 240mm rear rotor. The same caliper size and disc diameter is seen on the Yamaha YZ450F.

Fuel Economy and Real-World MPG

No real-world miles-per-gallon figures, but the RM-Z’s 1.7-gallon fuel tank is the same size as the Honda CRF450R, 0.1 gallon less than the Austrian competition, and 0.1 gallon larger than its Team Green and bLU cRU competitors.

Ergonomics: Comfort and Utility

The cockpit feels a bit smaller than other bikes in its class and is fine for riders 6-foot and under, but taller than that and the rider may want to look at a taller handlebar or lower footpegs.

2021 Suzuki RM-Z450 (Mason Owens/)

Electronics

While it has EFI and new MX-Tuner 2.0 connectivity, one downfall is that there is no electric start. Other electronics include Suzuki Holeshot Assist Control (S-HAC) and a traction management system.

Warranty and Maintenance Coverage

No warranty is available.

Quality

Although its suspension needs attention and its measured weight is heavier than the competition, the RM-Z is still fun because it corners well and has usable, now easily tunable, power.

2021 Suzuki DR-Z400SM (Suzuki/)

Ups

• Simple and reliable single-cylinder engine
• Easy to ride
• Retro vibes
• Affordable price tag
• Mirrors provide a great look behind the rider and offer plenty of adjustability
• With its long run on the market there are plenty of accessories available

Downs

• Retro lighting and dash in an advanced-tech world
• Footpegs provide not a whole lot of real estate
• Master cylinder needs to push more fluid through to the hydraulic brakes to enhance stopping power

Verdict

Retro from the overall design to the speedometer cable making its way to the front wheel, the DR-Z400SM provides some old-school charm for those looking for entertainment on a street-legal supermoto.

Overview

Since its production in the early 2000s, the Suzuki DR-Z400SM has been bringing fun to the pavement as Suzuki’s supermoto spinoff of the DR-Z400 dual sport. Its reasonable price in the market, tried-and-true engine, and flickable characteristics make it an attractive offering in the supermoto realm. Its street legality makes the world your go-kart track.

Updates for 2021

The DR-Z400SM flaunts different graphics as well as a black colorway that replaces last year’s gray one. It also sees a $100 price hike from the previous year.

Pricing and Variants

Suzuki’s supermoto has an MSRP of $7,499 which is more than a few thousand dollars cheaper than KTM’s returning 450 SMR and Husqvarna’s FS 450 (both $11,299) competition-only models. Kawasaki’s new KLX300SM, however, has a cheaper retail price of $5,999.

Powertrain: Engine, Transmission, and Performance

The DR-Z400SM is powered by a carbureted 398cc DOHC liquid-cooled single. Yes, carbureted. This helps Suzuki pass emissions and sound regulations and contributes to an overall smooth-running engine.

A couple of years ago we ran the DR-Z400S dual sport on our in-house dyno where it delivered 32.4 hp at 8,400 rpm and 24.6 pound-feet of torque at 5,900 rpm, so similar numbers can be expected with the SM’s single.

“It definitely has some zip in the lower gears…and a top speed of around 93 mph,” Motorcyclist’s Adam Waheed recounts in his MC Commute. The clutch does not require a heavy grasp, making it friendly for novice riders.

2021 Suzuki DR-Z400SM (Suzuki/)

Handling

“It is very light, very maneuverable, very easy to put where you want. You definitely feel some of the big bumps through the suspension, but in all the other smaller stuff the suspension goes over the bumps fairly well,” Adam Waheed stated.

The 49mm inverted Showa fork is sourced from the old RM250, and the swingarm and rear Showa shock is pulled from the RM-Z.

One unique element of the SM is that it has tubed tires, the reason other manufacturers might forgo the tubed tire option is that there is less reciprocating mass and less weight at the wheels. Tubed tires do have their advantages in that if the dreaded flat does occur, a simple tube swap is all that is needed to go about your business.

Brakes

Stopping the bike are hydraulic disc brakes, front and rear. The front brake has enough power to slow down the bike, but the master cylinder doesn’t have the power to push fluid through it and requires a firmer grasp at the lever to really slow the bike down, Waheed said.

The brake lever and brake pedal are both adjustable. ABS is not equipped on this machine.

Fuel Economy and Real-World MPG

The 2.6-gallon fuel tank (2.5 gallons for California) is large compared to the KTM 450 SMR’s 1.9-gallon fuel tank, for example. Miles-per-gallon figures are currently unavailable.

Ergonomics: Comfort and Utility

When Waheed rode the bike, he stated, “When sitting on the bike it feels like a dirt bike. That’s because it is a dirt bike.” He loved the slimness as well as the Renthal Fatbar with its upward bend that results in a commanding stance.

One main complaint Adam fielded was with the small footpegs. A little more room would provide more of a base to stand up on. The 35-inch seat height may also be somewhat intimidating to newer riders, but it is slightly lower than the DR-Z400 dual sport’s 36.8 inches.

Electronics

Following suit of its retro vibe, the bike offers rider aids and tech that are kept to a minimum. No ABS, no LED lights, no fancy gauge. The speedometer can be calibrated to varying tire circumferences if a swap is made, which is a nifty feature. Sometimes the bare essentials are all you need to have fun.

Warranty and Maintenance Coverage

This supermoto has a one-year unlimited-mileage warranty.

Quality

Some may be looking for a fully up-to-date supermoto, but the charm of the Suzuki DR-Z400SM is its retro looks, reliable engine, and street-legal fun.

Verdict

The KTM 450 SX-F receives praise in engine, suspension, ergonomics, and braking departments to make it a motocrosser worthy of its podium finish in the Dirt Rider comparison.

Overview

The 2021 KTM 450 SX-F continues to round out the podium in Dirt Rider’s 450 MX Comparison. The full-size motocrosser is admired for its torquey engine, neutral-handling chassis, light weight, and excellent brakes, all of which provide ample reason for it to place third in the DR comparison for the second consecutive year.

Updates for 2021

The 450 SX-F sees revised ECU mapping, updated and reworked front and rear suspension internals and settings, new Dunlop Geomax MX33 tires, a new hourmeter casing, and new graphics and color scheme for 2021. A notable addition to the Factory Edition model is the connectivity unit that comes standard and is integrated onto the new bar pad. This connectivity unit allows the rider to wirelessly tune the engine via the MyKTM smartphone app. Different Red Bull KTM Factory Racing graphics grace the bodywork of the Factory Edition.

Pricing and Variants

The 450 SX-F is available for an MSRP of $10,199 and the Factory Edition has an MSRP of $11,299.

The Factory Edition is fitted with a list of other features including: Red Bull KTM Factory Racing graphics kit, Akrapovič exhaust, orange anodized triple clamps, orange frame, orange rear sprocket, KTM Factory wheels, composite skid plate, semi-floating front disc with disc guard, Factory seat, holeshot device, Hinson Racing clutch cover, and the connectivity unit/MyKTM app connectivity as standard.

Powertrain: Engine, Transmission, and Performance

On our rear-wheel dyno, the KTM 450 SX-F produced 54.8 hp at 9,500 rpm and 34.6 pound-feet of torque at 7,400 rpm—impressive numbers to carry its light, CW-measured 234 pounds around the track.

In Dirt Rider’s extensive review, Andrew Oldar noted that the 450 SX-F has long, smooth, and predictable delivery and while it has a similar power curve to the CRF450R, the most powerful of the bunch, the KTM is slightly easier to control.

This powerplant not only appeals to vet and pro riders, but to amateurs as well with its strong engine and easy-to-ride mannerisms. A couple of downsides to the 450cc SOHC four-stroke would be that vibration is noticeable and the engine is not as lively as its competitors.

The Brembo hydraulic clutch system was also praised for having a touch more of an on-off feel compared to the others in its class.

Handling

Riders commended the 450 SX-F for its neutral handling and overall comfort. Comfort keeps on improving year after year due to the ever-updated suspension. With improvements made to the KTM’s WP suspension setup, the test riders had positive things to say about its suppleness, holdup, and ease of adjustability.

“The 450 SX-F initiates corners with ease and turns predictably,” Andrew Oldar said in the 450 Shootout. “While at speed, it holds a straight line and provides the rider with confidence.”

Brakes

When it comes to stopping power, the KTM 450 SX-F’s Brembo units are the best in the class.

Fuel Economy and Real-World MPG

No miles per gallon is currently recorded. Its 1.8-gallon fuel tank is one of the largest in the class and is the same as the Husqvarna FC 450 and GasGas MC 450F. The rest of competition ranges from 1.6- to 1.7-gallon tanks.

Ergonomics: Comfort and Utility

At a measured 234 pounds, the 450 SX-F is the lightest in the class, though, on the track it doesn’t always feel that way due to its smooth power delivery and slightly heavier engine feel, DR reported.

The chassis is long and narrow, with a well-proportioned rider triangle. The wide Neken handlebar throws the ergonomics off slightly. Another notable comfort characteristic is that the SX-F is the second quietest in its class, being only slightly louder than the FC 450.

Electronics

The SX-F is equipped with traction control, launch control, and a handlebar-mounted map select switch.

Warranty and Maintenance Coverage

Like its Husqvarna equivalent, the 450 SX-F comes with a 30-day warranty.

Quality

With its neutral handling, mostly comfortable ergos, commendable engine, and top-of-the-line Brembo brakes, the SX-F has what it takes to be a podium finisher.
