Now Offering Isotropic Transmission Service!

Isotropic Transmission Service

We are pleased to announce that we now offer isotropic transmission service. This process reduces stress risers and flattens raised areas on the surface of transmission components, creating a mirror-like finish. The result is a smoother surface, which leads to improved oil flow, less wear on parts, easier shifting, and a reduction in generated heat.

Plessinger Wins in Houston!

Aaron Plessinger!

Yamalube/Star Racing Yamaha rider, Aaron Plessinger, came away from the second round of the AMA Supercross 250 West season with a win in Houston, TX.

The Main Event saw Pro Circuit Kawasaki's Joey Savatgy grab the holeshot, with Plessinger well outside the top 10. Savatgy would lead the first 12 laps, fighting off challenges from his teammate, Adam Cianciarulo, and Troy Lee Designs KTM's Shane McElrath. Plessinger fought his way through the pack to eventually pass Savatgy for the lead on lap 12. Plessinger pulled away to secure the win, with Savatgy and Geico Honda's Chase Sexton rounding out the podium.

Yamalube/Star Racing Yamaha rider, Cooper Webb, recently won the 2016 Lucas Oil AMA Pro Motocross 250 Championship at Budds Creek MX in Mechanicsville, MD.

Entering the weekend with an 81-point lead in the championship, Webb could wrap up the title after the first moto if he were to finish on the podium. But two early crashes on the first lap caused Webb to work his way through the pack. He would eventually finish in sixth position, which meant a champion couldn't be crowned until Moto 2.

In Moto 2, another bad start for Webb meant another come-from-behind performance. He continuously clawed his way toward the front of the pack and ended the race in third position, granting him enough points to wrap up the 2016 title with one race remaining in the series.

Zach Osborne earned his first overall win of his career with 4-1 moto scores. Alex Martin, Austin Forkner, Adam Cianciarulo, and Webb would round out the top five overall, respectively.

Yamalube/Star Racing Yamaha riders Cooper Webb and Aaron Plessinger finished first and second this past weekend at Unadilla MX in New Berlin, NY.

After a restart in Moto 1, Webb was able to come out in second position on the opening lap, just behind Adam Cianciarulo. He would eventually make the pass and lead the race all the way to the finish. Joey Savatgy would also make his way around Cianciarulo, and finish second just in front of a fast-charging Plessinger, who made a few passes late in the race.

In Moto 2, rookie Austin Forkner grabbed the early holeshot and began to stretch out a lead on the rest of the field. Webb would eventually reel Forkner in and take over the lead toward the end of the race. Troy Lee Designs/Red Bull KTM rider, Jessy Nelson, would then suffer a terrible crash, which resulted in the race being red flagged. Since more than half of the race was over, the race was ruled as completed. The final running order was Webb, Forkner, and Plessinger, respectively.

Webb's 1-1 scores granted him the overall win, with Plessinger taking second after his 3-3 scores. Forkner's 7-2 scores gave him third overall.

Jessy Nelson is in the thoughts and prayers of everyone here at Crank Works, as we pray he makes a speedy recovery. If you would like to support Jessy in his recovery, a recovery fund has been graciously set up by Road2Recovery, and you may make a donation HERE.

The second round of the AMA Pro Motocross Championship, which took place at Glen Helen Raceway in San Bernardino, CA, proved to be another exciting race.

In the 250 class, Alex Martin got out to an early lead in the first moto, followed by Cooper Webb and rookie Austin Forkner. Webb would eventually make a pass in the closing laps to take the moto one win ahead of A. Martin and Forkner.

Moto two would see Jeremy Martin grab the holeshot, with Jesse Nelson and A. Martin in tow. J. Martin led the entire moto to the finish, and A. Martin was able to make the pass into second and finish ahead of Nelson.

A. Martin earned the overall win with 2-2 scores, edging out his younger brother and defending national champion, J. Martin, by one point after his 4-1 finishes. Webb rounded out the podium with 1-4 scores. Forkner and Aaron Plessinger would take 4th and 5th overall, respectively.

Three Crank Works-sponsored riders finished on the podium this past weekend at the Springfield Mile in Springfield, IL.

Crosley/Howerton Kawasaki's Bryan Smith continued his dominance of the Mile, winning his third consecutive Mile of 2016. He would battle tooth-and-nail with a slew of Harley-Davidson-mounted riders, including defending champion Jared Mees, and Brad Baker.

Smith would edge out Mees by a margin of just 0.119 seconds at the finish. Braker would round out the podium, making for a podium sweep of the three Crank Works riders.

Cooper Webb Wins 250 West Title!

Cooper Webb Goes Wins 250 West Championship!

Crank Works-sponsored rider, Cooper Webb, was crowned the 250 West Supercross champion for the second year in a row.

With 16 points separating Webb and Joey Savatgy, it all came down to the final 250 West round in Las Vegas. To add to the excitement of the final round, an extra element was thrown in. Rain began to downpour, and for the first time since many can remember, Las Vegas was a mud race.

Webb only needed to finish in 12th position to wrap up the title, but racing with a broken wrist and in muddy conditions proved to make that seemingly simple task very challenging. After completing lap one in 12th place, Webb did what he could to remain at least that high up for the remainder of the race. Savatgy rode to a commanding race win, but would ultimately finish one point behind Webb in the final point standings.

Everyone here at Crank Works would like to congratulate Cooper Webb and the entire Yamalube/Star Racing Yamaha team on their second consecutive 250 West championship!
