Yamaha will adopt a seamless-shift transmission on its M1 factory bikes next season for Jorge Lorenzo and Valentino Rossi, European media reported.
Honda and Ducati have used seamless shifting since 2011. Lorenzo reportedly has urged Yamaha engineers to follow suit since their rivals introduced the system.
A seamless-shift box shaves only one-tenth of a second from a lap, according to Honda and Ducati. But it offers more stability as the rider climbs up the gears under acceleration.
"They still have a medium advantage with the gearbox, and that gives them an advantage in some fast corners like in Qatar or Phillip Island," Lorenzo said of Honda. "When they shift up, the bike doesn't move, so this is an advantage they have."
Ducati has experimented with modified transmissions several times, including an semi-automatic on their Superbikes in the early 2000s and a modified tranny on their 2005/2006 MotoGP bike.
