Twin shocks are a non-functional design related to emotional, retro appeal, right? No, they are a cutting-edge design employed by Yamaha on its latest MotoGP prototype. No, really!
At the Jerez IRTA test last week, Yamaha brought out a unique prototype employing twin, Ohlins rear shocks, an inverted swingarm, and an experimental Deltabox chassis (as well as a redesigned, underseat exhaust system). Testing this unique beast was Yamaha’s former MotoGP contender Norick Abe.
Yamaha published comments by Shuji Sakurada, technical test manager for MotoGP, explaining that “chassis development” is the main focus of the prototype, and that the twin shocks “could improve traction and tire life” over the more conventional, single-shock design employed on race bikes. Yamaha is also experimenting with frame flex.
Looking at the best photos we could find (displayed with this article) it almost appears like the shocks employ linkage at their top mounting point, rather than the more conventional location at the bottom mounting point. There also appears to be a rod tying the rear of the frame to the steering head, on each side of the bike, perhaps, in order to measure chassis flex.
