Yamaha patents a double clutch layout on a R1!
The double clutch layout is depicted on the drawings that Yamaha has submitted, three of them are given below. The double clutch system is depicted at the two sides of the crankshaft, left and right of the engine.
It is not clear if the double clutch system, following Honda¢s DCT eg the VFR 1200F etc, will ever be mounted on a Yamaha sportbike like the R1.
