Yamaha’s Jamie Hacking used WP fork internals to win the AMA Supersport race at Barber Motorsports Park. “We’re just exploring other avenues,” Tom Halverson, manager of the factory Yamaha Supersport team, told Roadracingworld.com during Friday morning practice at California Speedway. “Our goal is to win races, of course, and we want the best equipment on the bikes to do that. Right now we don’t have a suspension sponsor. So we’re just trying to see if we’re missing something or if we can learn something and go from there.” Several of the Yamaha YZF-R6s of the factory Supersport team and the YZF-R1s of the Graves Yamaha Superstock team, both long-time users of Ohlins components, were equipped with WP components for Hacking, Damon Buckmaster and Aaron Gobert to try Friday morning at California Speedway. Yamaha’s Jason DiSalvo, however, continues to stay with Ohlins suspension on his bikes. Halverson said it is up to each of his four riders to decide whether they want to stay with Ohlins suspension components or switch to WP. Halverson said Yamaha was attracted to WP after Yamaha’s World Supersport team began using WP products successfully. Yamaha’s AMA teams first tried the products on its Superstock bikes while testing at Barber in March, and some of the Yamaha riders used WP components on their bikes during the Barber race weekend, including Hacking.
