Crescent Suzuki, which will step-up from BSB to WSBK next season, has announced that Japanese tuning company Yoshimura will build, supply and develop the engines and exhaust systems for the team's GSX-R1000s.

Yoshimura engineers have already spent some time at the Crescent race headquarters in Verwood and evaluated the development already made with the 2011 engine.

The Japanese company will now work alongside Crescent to develop the motors further and make them as competitive as possible in time for the start of the 2012 season.

"For us as a team it is a significant level of assistance and a substantial boost to our performance potential," said Crescent team principal Paul Denning. "The Yoshimura company was built on engineering the best possible performance from engines and exhaust systems, and that principle has never changed.

"It is also very pleasing that the whole attitude to the project is of open communication and using the best combination of Yoshimura's own concepts and ideas and those which already exist in the Crescent developed engine."

The Yoshimura collaboration - and other soon-to-be-announced sponsorship and partner agreements - suggests that Crescent will not be relying on direct Suzuki factory support for its new WSBK programme.

Many will see that as a wise decision given the uncertainly over Suzuki's racing activities, including the expected loss of the MotoGP project and no confirmation of Alstare Suzuki's 2012 plans.

Yoshimura has made wild-card WSBK entries of its own in recent years, but will be hoping that the Crescent deal can replicate the kind of success enjoyed by the company in AMA competition.

"We at Yoshimura greatly appreciate this collaboration and it will be our highest priority," said Yoshimura Japan owner Fujio Yoshimura. "Thanks to Paul and Crescent Suzuki for trusting our engine tuning capabilities and our passion towards competing at the front of the 2012 WSBK Championship Series."

Crescent team manager Jack Valentine added: "I'm very excited with the 'Powered by Yoshimura' partnership for next year and after spending time with Fujio, Yohei and the Yoshimura team both in Portimao and at the Crescent workshops, I can see they share the same passion and vision as our team. With that in mind it should make for a formidable partnership in SBK 2012."

Leon Camier has been confirmed as one of Crescent's WSBK riders. With a lack of competitive MotoGP opportunities available, Crescent's BSB title runner-up John Hopkins is hotly tipped to take the second seat.
