Rockstar Energy Husqvarna’s Zach Osborne took a first-career 450MX overall as Dylan Ferrandis dominated 250MX today at Loretta Lynn’s 2020 Lucas Oil Pro Motocross Championship opener.
The opening premier class moto was controlled by Jason Anderson (Rockstar Energy Husqvarna) as he stormed to the front on lap one and delivered a 4.895s win.
Anderson led factory Husqvarna teammate Osborne, who pressed through the field from the back of the top 10 into the runner-up position. A hard-charging Justin Barcia (Monster Energy Yamaha) came from even further back to third, with Marvin Musquin (Red Bull KTM) fourth and teammate Cooper Webb fifth after circulating as high as second.
The first appearance of Adam Cianciarulo (Monster Energy Kawasaki) resulted in P6, passing teammate Eli Tomac in the latter stages, as Blake Baggett (Rocky Mountain WPS KTM), Joey Savatgy (JGRMX Yoshimura Suzuki) and now privateer Benny Bloss (Husqvarna) were the top 10.
The holeshot belonged to Fredrik Noren (JGRMX Yoshimura Suzuki) alongside Savatgy, while another to put on an early attack was top qualifier Chase Sexton (Team Honda HRC), but he made an error while battling for the podium and wound up 13th.
Winning the second moto this afternoon at the ranch saw Osborne earn his first 450MX victory, overcoming a late challenge from Tomac to cross the line 3.605s ahead of the number one plate-holder and Sexton was third.
It was initially Cianciarulo who led the way only to crash out of contention with bike damage, handing Osborne the lead and that’s where he stayed.
Behind the top three came Baggett and Musquin, while opening race victor Anderson was among the top three early, only to gradually slide down the order later in the race to sixth.
Barcia recovered from an early fall for eighth ahead of Webb, Dean Wilson (Rockstar Energy Husqvarna) and Max Anstie (HEP Motorsports Suzuki). Overall via a 2-1 score, Osborne stood in the middle of the podium ahead of Anderson and Tomac.

In 250MX, Ferrandis captured the first moto victory of the season with a commanding ride, hitting the front on lap one and then inching away from the field to a 19.802s advantage by the checkered flag.
He was followed by Jeremy Martin (Geico Honda) in second, with RJ Hampshire (Rockstar Energy Husqvarna) enjoying a strong return to racing in third, while the fast-starting Shane McElrath (Monster Energy Star Yamaha) crossed the line fourth and Alex Martin stormed to a top five.
Geico Honda’s Jett Lawrence was able to salvage sixth following a fall mid-moto, followed by Derek Drake (TLD Red Bull KTM), Mason Gonzales (Rock River Yamaha), Cameron McAdoo (Monster Energy Pro Circuit Kawasaki) and Justin Cooper (Monster Energy Star Yamaha), who had scored the hole-shot.
Elsewhere, Hunter Lawrence (Geico Honda) went out on the opening back with a mechanical, while Monster Energy Pro Circuit Kawasaki replacement Mitchell Harrison had been inside the top five until he stalled and couldn’t restart, dropping down the order to 23rd.
Another win in moto two for Ferrandis sealed him the overall and early points-lead in the season, with the top three being the same as the opening outing as Hampshire was second, 13.199s in arrears and this time getting the better of Jeremy Martin in third.
In fact, the entire top five was identical, with early leader McElrath fourth and Alex Martin a solid fifth. Sixth was an improvement for McAdoo this time out, trailed by Jett Lawrence, Cooper, Harrison and Brandon Hartranft (TLD Red Bull KTM).
Ferrandis was sixth at the end of the opening lap, climbed into the top three by lap four and led from lap seven, going on to dominate for the second race in a row this afternoon. Overall it was Ferrandis atop the podium, joined by Hampshire and Jeremy Martin.
Jett Lawrence’s 6-7 scores resulted in sixth overall to begin his first full season outdoors, while brother Hunter Lawrence rebounded for 14th in moto two, putting him 17th for the weekend following that non-finish in the opening encounter.
The 2020 Lucas Oil Pro Motocross Championship will continue with round two of nine scheduled next Saturday, 22 August, once again at Loretta Lynn’s.

A historic first victory for GasGas in the MXGP World Championship was earned by Glenn Coldenhoff at Kegums on Sunday, going 2-1 for the overall aboard the factory MC 450F.
The first of three-straight grands prix in Latvia, Coldenhoff trailed world champion Tim Gajser (Team HRC) in moto one, before standing atop the podium at the end of moto two.
Moto one belonged to Gajser after going back and forth with Coldenhoff, whole Romain Febvre (Monster Energy Kawasaki) claimed third position. The second outing saw Coldenhoff keep Jeremy Seewer (Monster Energy Yamaha) at bay, with Febvre again third.
Overall it was Coldenhoff who took the win ahead of Gajser – who was fifth in moto two – and the consistent Febvre. Current points-leader Jeffrey Herlings (Red Bull KTM) went 4-4 for fifth overall, while Australian Mitch Evans (Team HRC) was 19th on return from shoulder surgery.
MX2 belonged to moto one winner and red plate-holder Tom Vialle (Red Bull KTM), who went 1-2 for the round. After finishing 16th in the first race, Jago Geerts (Monster Energy Yamaha) won moto two to salvage sixth overall.
Instead, filling the round podium was F&H Kawasaki Racing’s Roan Van de Moosdijk and teammate Mathys Boisrame, while Australian Jed Beaton (Rockstar Energy Husqvarna) finished ninth, Nathan Crawford (Team Honda 114 Motorsports) 12th and his teammate Bailey Malkiewicz 27th.
Both Beaton and Crawford delivered strong performances in the second outing for sixth and eighth positions respectively, bouncing back from a more challenging opening affair earlier in the day when they were 15th and 14th respectively.
The 2020 MXGP World Championship will continue this Wednesday, 12 August, with a maiden mid-week round for the MXGP of Riga that will again be hosted at the Kegums circuit in Latvia.

Latest Works Edition also introduced for new model year.

Honda has taken the wraps off its 2021 CRF450R, beginning a new chapter of premier class motocross models that has been inspired by a ‘razor sharp cornering’ development theme.
The all-new CRF450R is guided by three main goals for 2021, being improved power, improved handling and improved consistency over the course of a moto.
That first point was addressed by making changes intended to increase the engine’s horsepower and torque, particularly in the bottom-end of the range. The second objective was addressed by optimizing chassis rigidity, altering geometry and reducing weight. The final target was pursued via updates to the clutch, as well as the ergonomics for improved rider movement.
As is often the case, benefits overlapped, with improvements in one area leading to benefits in other areas. For example, the power and torque increase result in changes to power delivery that make the machine more manageable in corners. Similarly, the reduced weight not only aids cornering, but promotes a more consistent performance by the rider over the course of a race.
Speaking of weight savings, the reduction here is an example of something that was only achievable during an overall redesign and only by accumulating small benefits in myriad areas. It boasts a 1.36 kilogram weight reduction overall.
The CRF450R engine has undergone a number of significant updates aimed at improving bottom-end and midrange power, making for a linear delivery that is strong but manageable, even as the rider tires. In addition, peak power is up 0.8 horsepower above 5000rpm.
The design of the Unicam cylinder-head has been updated, with the decompressor system’s counterweight relocated from the right end of the camshaft to the left. This improves combustion stability in the extremely low rpm range and contributes to a strong, but manageable, power delivery in corner exits, for example, as well as resistance to stalling. The magnesium cylinder-head cover has also been designed with a thinner material, for weight savings.
The engine’s exhaust port has been centralised, ovalised and straightened, achieving improved exhaust efficiency and revised torque characteristics, for a linear delivery that continues into the high rpm range. As before, a five-hole piston oil jet and dual 12mm drum scavenge pump manage lubrication.
The CRF450R features a downdraft intake design that delivers strong, efficient power, but the air boot has been drastically enlarged (from 1.8 litres on the clean side of the air filter to 4.1 litres), resulting in better torque at low rpm. In addition, the rubber ring has been eliminated to simplify filter cleaning, with an external frame added to ensure a good seal is maintained. The air box is now accessed with the removal of a single side-panel bolt.
The angle of the fuel injector has been increased from 30 degrees to 60 degrees, enabling the spray to reach all the way to the back of the butterfly, thus cooling the upstream side of the intake path, improving intake efficiency and torque feel. In addition, the fuel pump is now smaller and 120 grams lighter. It’s affixed via a simplified mounting system using only four fasteners instead of six. Fuel pressure and filter life are both unaffected.
For 2021, the CRF450R makes the switch from two mufflers to one, reducing weight and improving bottom-end torque delivery. The entire exhaust system now weighs 3.8kg, a reduction of 1.2kg from the previous model.
With the engine’s new centralized exhaust-port location, the exhaust header is now routed 74mm closer to the engine on the right side, while the single, right-side muffler has been reshaped to move its outer surface 13mm inboard. The combined result is a slimmer body (including external parts), contributing to freedom of movement for the rider. Two resonators (one after the front U-bend and another at the upstream end of the muffler) boost power and reduce noise, while the heat shield has been eliminated to reduce weight.
With an eye toward increasing clutch durability, engineers increased clutch volume by 27 percent while also adding an eighth clutch plate and using stiffer springs. In addition, a friction spring was added to suppress resonance and greatly improve power delivery. These changes reduce clutch slip by 85 percent at peak power, as measured by a chassis dynamometer.
To facilitate clutch actuation and encourage consistent performance, a hydraulic clutch is now utilized as on the HRC factory machines. As a result, the force needed to pull the handlebar lever is reduced. Depending on where in the lever stroke the measurement is taken, the reduction can be as much as 10 percent compared to the previous model, even with the stiffer springs.
A gear-position sensor allows the use of three specific ignition maps for first and second, third and fourth, and fifth gears. There are options for Standard, Smooth and Aggressive ignition maps, selectable via an all-new handlebar-mounted switch, enabling simple tuning depending on rider preference or course conditions.
In addition, Honda Selectable Torque Control (HSTC) still offers three levels of intervention. HSTC monitors rpm spikes and responds by temporarily reducing torque by retarding ignition timing and controlling PGM-FI to aid rear traction.
A number of significant chassis revisions were incorporated in order to improve cornering. With these changes, geometry is now different as the wheelbase is now 1mm shorter (at 402cm), rake is relaxed 0.5 degrees (at 27.7 degrees), trail is reduced by 2mm (now 114mm), the swingarm angle is 0.9 degrees steeper (at 14.5 degrees), the seat height is 5mm taller (at 96.5cm), ground clearance is increased by 8mm (now 33.5cm) and the distance from the front axle to the swingarm pivot is 1.8mm longer (at 91.4cm).
As before, heavier components are positioned centrally and as low as possible. The result is improved cornering without sacrificing high-speed tracking, in addition to reduced squat under acceleration and less pitching during hard braking.
An all-new frame uses narrower main spars, a redesigned downtube and features rearranged reinforcement ribbing on the backside of the pivot plate, changes that contribute to an overall weight reduction of 0.69kg, with the new frame weighing just 8.3kg. Lateral rigidity is reduced by 20 percent, resulting in supple feel that improves cornering—while vertical rigidity is maintained.
The subframe features a simplified design that enabled the elimination of a separate seat support, achieving an overall weight of just 900 grams, which is over 300 grams down from before. In addition, the swingarm is now narrower, providing increased clearance in ruts, with rebalanced rigidity tuned to match the frame and improve rear traction and cornering.
Front suspension comprises a 49mm inverted Showa coil-spring fork that follows the basic structure of that on the 2020 CRF450R and a gas-liquid separation structure, but suspension stroke has been increased by 5mm to better absorb rough terrain while also reducing pitching. In addition, the axle holders have an updated design for increased rigidity.
The upper and lower triple clamps have both been redesigned as well, with rigidity rebalanced via updated reinforcement ribs, delivering increased flex characteristics for improved handling and feel through a corner.
The Pro-Link rear-suspension system uses a Showa shock absorber whose shape has been adapted to work with the new frame, with adjusters moved from the left side to the right. Weight was cut here as well, by switching to an ultra-light steel shock spring. The link ratio and rear travel has also been changed so that acceleration-triggered rear-end squat is reduced.
Black D.I.D. rims deliver durable performance and good looks. Petal-style brake rotors disperse heat and a low-expansion front brake hose gives strong feel and consistent stopping power. The 2021 CRF450R comes with Dunlop’s excellent Geomax MX33 tyres. Developed with the help of top motocross pros, MX33s feature technologies that deliver superior grip, slide control, bump absorption and durability.
The technical changes to the CRF450R enabled the adaptation of slimmer bodywork, which facilitates rider movement. For example, the lack of a left-side muffler made possible a side panel that is 50mm more inboard and even the right side panel is moved 20mm inboard thanks to the new muffler shape. Together, the changes result in a 70mm reduction in width at the rear of the bike, substantially benefitting rider movement and, consequentially, cornering. The junction of the radiator shroud and the side panel is smoother as well.
The radiator shrouds are new as well and each is now produced in a single piece instead of two separate parts. Computational Fluid Dynamics (CFD) were used to design new air-outlet vents in the shrouds. The radiator grills have also been revised to optimise the number of fins and their angle, resulting in a five percent improvement in cooling performance, without changing vehicle width at the shrouds.
Whereas the seat was previously installed by sliding it forward onto the subframe and then securing it at the rear, the new seat base has rearward-facing tongues and front-located mounting tabs. This eases installation, and acceleration forces keep the seat securely in place. The 6.4 litre fuel tank is once again made of lightweight titanium but has a new design, and the plastic tank cover has been eliminated.
During the model’s redesign, engineers looked for and capitalised upon every opportunity to cut weight for improved handling. For example, only eight fasteners are used to secure all of the main bodywork components including both radiator shrouds, both side panels and the seat, instead of 12 previously. In addition, all of the bolts for the main bodywork parts now have 8mm heads, simplifying maintenance.
A further 98 grams were cut by combining what used to be two left-side handlebar switch assemblies into a single cluster that addresses several functions – engine stop, ride modes and HSTC. The starter and HRC launch control are on the right side of the Renthal Fatbar handlebar.
As before, there are two locations for the handlebar clamp and the clamp can be turned 180 degrees. As a result, four different mounting positions are possible, through a range of 26mm. Routing the throttle and clutch control cables behind the handlebar instead of in front allowed for a weight reduction of 100 grams high on the bike.
Each of the CRF450R’s updates is transferred to the high-spec CRF450RWE (Works Edition) motocross machine, which in addition to its already illustrious list of trick parts, features a Twin Air air filter plus Hinson clutch basket and cover for 2021.
Additional updates include a lightweight full titanium Yoshimura exhaust system (header and muffler), and like the CRF450R, the system has switched from two mufflers to one, reducing weight and improving bottom-end torque delivery.
Compared to the CRF450R, the CRF450RWE’s lower fork legs are coated in titanium nitride to minimize stiction and promote smooth action. The CRF450RWE has special D.I.D DirtStar LT-X rims that are even stouter than the standard D.I.D rims of the CRF450R. A special gold RK chain delivers power to the rear wheel.
Rounding out the package are Throttle Jockey graphics, straight off the Team Honda HRC factory machines of Ken Roczen and Chase Sexton. Due to arrive in October, Honda Motorcycles Australia is yet to confirm 2021 CRF450R pricing or if the Works Edition will be available locally for the new year.

Renowned Italian off-road brand Beta has made an unexpected move into motocross with the introduction of its 2021 model Beta 300 RX in the United States.
Specifically powered by a 293.1cc two-stroke engine, the new Beta 300 RX has been tuned for motocross, featuring electric start, a six-speed transmission and an adjustable power-valve.
The chassis includes a frame purpose-built for the RX model, as well as a KYB closed cartridge front fork and Sachs rear shock, which have internal settings that were developed by Beta USA’s in-house suspension department.
“We wanted to build an MX bike that utilised many of the characteristics that our off-road race bikes have, but with more power and stiffer suspension,” Beta USA president Tim Pilg commented. “The RX model shows how much fun a two-stroke can be. The sound and feeling of the bike is unmatched and I hope our future owners of the model will appreciate the effort put into the bike – it is truly special.”
Additional features of the RX 300 include a lightweight lithium battery, 19-inch rear wheel, push-button seat removal, Brembo hydraulic clutch, Nissin front and rear brakes with oversize rotors, plated Arrow exhaust pipe, composite rear sub-frame and a V-Force reed assembly. It’s unclear if Beta Motorcycles Australia will import the model.
Interestingly, Beta’s RX 300 promotional edit includes Jake Weimer, the 2010 250SX West champion in Monster Energy Supercross riding alongside Beta USA Factory Team manager Rodney Smith – a five-time Grand National Cross Country (GNCC) champion and current factory Beta rider Chance Fullerton.
Beta has emerged as the dominant force in the Enduro World Championship during recent seasons, capturing the EnduroGP and Enduro 1 titles with Brad Freeman, while Steve Holcombe rode to the Enduro 3 crown in a convincing display from the Italian manufacturer.
Updates also made to KX450 in addition to off-road variants.

Kawasaki has uncovered the 2021 KX250 and KX450 models, the former of which is all-new and includes an electric start for the first time in addition to a haul of performance-increasing upgrades.
The 2021 model KX250 builds on engine changes from the previous year to make it the most powerful KX250 to date. Its striking appearance features slim, ergonomic bodywork, plus it now has a factory-style 1-1/8” Renthal Fatbar Handlebar.
In addition to a high-revving engine, it now features new electric start, new coned disk-spring hydraulic clutch and a new slim aluminum perimeter frame that improves handling to enable quicker lap-times, making the KX250 even more potent on the race-track.
The powerful engine of the KX250 features upgrades to both the top- and bottom-end for increased power, improved brakes offer more control when harnessing the power of the stronger engine and an updated KX450-style frame and fine-tuned suspension settings to create the ultimate performance package.
Engine changes are inclusive of new processing for intake and exhaust ports, exhaust cam timing, stiffer valve springs, combustion chamber design and flatter piston crown, longer connecting rod, lighter crankshaft design and revised pressure balance inside the crankcase.
Complimenting the electric start, a lightweight, compact Li-ion battery helps keep weight down, as does an automatic centrifugal decompression system fitted to the exhaust cam, which lifts one exhaust valve to facilitate starting.
The KX250’s new slim aluminium perimeter frame is based off of its KX450 counterpart and with lightweight, nimble handling and slim ergonomics in mind. The new frame offers a better overall rigidity balance and, while many of the parts are common with the KX450’s frame, the cast parts like shock tower mount and engine hangers were designed specifically for the needs of the KX250.
Adding to the frame’s rigidity balance is the use of the engine as a stressed member. The steering head area, main frame rails with updated cross-sections, line for the swingarm brackets, and wider lower frame rails have all been revised and contribute to the overall rigidity balance.
The addition of a KX450 swingarm delivers the rigidity necessary to match the frame and helps to increase traction at the rear wheel. The center of gravity and key dimensions such as swingarm pivot, output sprocket and rear axle locations have all been carefully selected so that the rear tire drives the bike forward.
The lower triple clamp has been revised for optimised rigidity and reduced weight, while contributing to the front’s ability to absorb bumps. In the rear, linkage ratios have been revised, now using the same as those found on the KX450 motorcycle, contributing to both increased absorption and damping performance. Both front and rear suspension feature new fine-tuned settings that are designed to match the frame.
For 2021, a revised design on the top of the fuel tank allows an even flatter progression from the seat to the tank, which gives the rider greater freedom of movement and facilitates sitting farther forward. The single-piece radiator shrouds are now slimmer where they come in contact with the rider’s legs and positioned closer to the frame. Engine covers have been redesigned and are smooth in order to not impede rider movement.
Meanwhile, the Kawasaki KX450 returns as the flagship model in the line-up for 2021 and boasts several new updates to maintain its edge as a leader in its class. For 2021 the KX450 receives engine updates for increased performance and a new 1-1/8” Renthal Fatbar handlebar.
Those engine updates include a dry film lubricant coating on the piston skirt, while larger diameter clutch plates and revised friction material have also been utilized. A coned disk-spring hydraulic clutch offers improved clutch performance.
The championship-proven technology of KX race machines has now been purposely tuned for off-road competition, as Kawasaki announces all-new race ready off-road KX XC models with the all-new 2021 KX250XC and KX450XC models. These are in addition to the KLX450R, which remains as the brand’s registrable model.
These models share many winning traits with their motocross counterparts including the engine, frame, chassis and styling, paired with unique cross-country tuning and settings such as suspension settings, gearing, off-road 21/18-inch wheel combination, Dunlop Geomax AT81 tires, brake components, skid plate and kickstand. Softer suspension settings and shorter gearing ratio help to create the optimal handling off-road race package for the KX XC line-up.
Complete information on the entire 2021 KX motocross and off-road range is available now at www.kawasaki.com.au. Models are due to arrive in Australia during the third quarter of this year.

KTM has taken the covers off its 2021 motocross range, featuring enhancements that have flowed through from research and development of the Austrian brand’s factory racing teams that make for the most technically-advanced, ‘Ready To Race’ range to date.
The feedback collected by racing achievements globally helped KTM R&D update the KTM SX model range for 2021 with clear core objectives, to create the lightest, best-handling, most powerful, usable and well-equipped motocross bikes.
Improvements for 2021 across the full-size range focus on suspension and chassis modifications, tweaks to engine architecture to further enhance reliability, new Dunlop tyres and a reworked graphics aesthetic.

The WP XACT front forks and rear shocks have been overhauled with new components as well as being reconfigured with a slightly firmer standard setting to increase confidence and comfort across a wider spread of surfaces. Dunlop’s Geomax MX-33 is the rubber of choice for the KTM SX models thanks to its versatility and race proven performance.
As the flagship model in the four-stroke range, the KTM 450 SX-F benefits from modifications to the piston, crankshaft, engine casing, rocker arms and shift locker to further hike the bike’s excellent reliability, shave more weight and aid practicality in terms of general maintenance.
In addition, the 2021 KTM 450 SX-F together with the new KTM 350 SX-F and KTM 250 SX-F machines can connect with the advanced myKTM app using an extra Connectivity Unit kit, available in the KTM PowerParts catalog.

With the bar pad-integrated Connectivity Unit fitted and the myKTM app installed, riders can personalise their KTM SX-F according to their preferences and track conditions without technical assistance. Offering the finest technical touch, the myKTM app allows for a wide spectrum of adjustability on the fly, a privilege that was limited to elite KTM factory riders until recently.
As a towering example of power-to-weight ratio excellence in the KTM two-stroke range, the 2021 KTM 125 SX is boldened with a fresh piston and clutch internals, with the treatment extending to the 250cc-challenging KTM 150 SX.
KTM treats its Sportminicycle roster with the same ground-up priority for development as the full-size bikes. The KTM 85 SX, KTM 65 SX and KTM 50 SX and KTM 50 SX Mini therefore count on a new throttle assembly for better and smoother throttle action.
For the KTM 85 SX, braking potential is much higher thanks to larger discs and a completely new front and rear brake system made by Formula. All three junior motocrossers now have a tapered handlebar allowing fitment of ODI lock-on grips. For the KTM 50 SX and KTM 50 SX Mini, the new tapered handlebar allows fitment of thinner grips.
The 2021 KTM SX range will become available at KTM dealers worldwide from June 2020 onwards. For more information, visit www.ktm.com.

The 2020 Monster Energy Supercross championship will go down to the wire this weekend after Cooper Webb withstood Eli Tomac to take victory on Wednesday in Salt Lake City.
Tomac needed to defeat Webb and Ken Roczen (Team Honda HRC) today in order to seal the title with a round to spare, but Red Bull KTM’s Webb proved too tough.
Incredibly, Tomac went through the first turn in last position, made his way to 12th by the end of the opening lap and then charged forward from there to the runner-up result, falling just short of the win by 2.214s.
The road into P6 was relatively straightforward over the first 10 laps, but the challenges mounted as he reached the likes of Jason Anderson (Rockstar Energy Husqvarna), Roczen and Zach Osborne (Rockstar Energy Husqvarna) for podium position.
Webb made a move on longtime leader Osborne – who made a mistake in the process – with three minutes remaining and Tomac followed him straight through, setting up the face-off between the duo in the closing laps. But Webb held on and, as a result, he kept his 450SX defence alive.
In the end, behind Webb and Tomac came Osborne as he scored his third podium at Rice-Eccles Stadium in six races, keeping Roczen at bay and with top-qualifier Anderson finishing fifth.
Positions six through 10 included Justin Brayton (Team Honda HRC), Malcolm Stewart (Smartop Bullfrog Spas Honda), Martin Davalos (Monster Energy Team Tedder KTM), Justin Barcia (Monster Energy Yamaha) and Blake Baggett (Rocky Mountain KTM WPS).
After winning the LCQ, Australian icon Chad Reed (Mountain Motorsports CR22 Racing KTM) finished 15th in the main event ahead of what will be his final ride as a full-time rider this weekend in Utah.
Entering the 17th and final round of the 2020 Monster Energy Supercross, an FIM World Championship, series on Sunday, Tomac has a 24-point advantage in the standings and will need just two points to clinch the crown regardless of where Webb finishes.

There was no denying Chase Sexton a fourth victory in the 2020 Monster Energy Supercross championship, taking him another step closer to defending his 250SX East title.
Sexton started behind title rival Shane McElrath (Monster Energy Star Yamaha) before pushing his way past as the halfway point approached.
It was a convincing ride from the Geico Honda rider, sprinting away to a 3.427s advantage over McElrath, who had no answers in Salt Lake City 6 tonight. Completing the top three was Colt Nichols (Monster Energy Star Yamaha).
Finishing fourth was rookie Pierce Brown (TLD Red Bull KTM), who was in podium position until Nichols moved by, and the top five was filled by another newcomer in Jo Shimoda (Geico Honda).
Top of the non-factory riders was Kyle Peters (Phoenix Racing Honda) in sixth, ahead of Enzo Lopes (ClubMX Yamaha), Chris Blose (Chaparral FXR Racing Honda), Lorenzo Locurcio (Team PR-MX Kawasaki) and Chase Marquier (Manluk Racing Honda) inside the top 10.
Sexton will carry a six-point lead over McElrath entering this Sunday’s 250SX Showdown round at Rice-Eccles Stadium, the final round of the 2020 Monster Energy Supercross championship.
