Spanish media is reporting both Jorge Lorenzo and Valentino Rossi will have a seamless transmission in their Yamaha Factory Racing M1 machines this weekend at Misano. There is no confirmation of this from Yamaha, but team exec Lin Jarvis said in July that Yamaha's version of the seamless transmission would not debut until Yamaha were convinced that the system was safe and reliable.
It is said that the original plan was to test the new transmission one more time after Misano and then bolt it to the factory team's bikes for the Grand Prix of Aragon on Sept. 29. But Lorenzo and Rossi reportedly pressured Yamaha engineers in Japan to accelerate that plan so the smoother-shifting gearbox would be ready this weekend in Italy.
Reportedly rider power prevailed. They both liked the system during testing last month in Brno, and engineers in Japan are convinced the system is safe, reliable and faster.
Depending on your definition of "seamless transmission", seamless transmissions have existed for over 30 years, albeit largely in autos and auto racing (cars). Ducati tested a version of a seamless transmission on their old 996 Superbike with Luca Cadalora as the test rider and Ducati MotoGP has had a version of a seamless transmission for several years now. However Honda's version of the unique system has proven to be an advantage that Yamaha can no longer ignore.
Misano is Valentino Rossi's home race so he will be under intense self-pressure to wring everything he can from the championship-winning M1. Will a seamless transmission be the mechanical or physiological difference Rossi needs?
