Yamaha recently filed a new patent application that reveals significant innovations in the design of electric motocross bikes.
The focus is specifically on the transmission to improve traction and increase torque to suit off-road competitions. Yamaha’s experience with the TY-E trial bike, which faced similar challenges in providing instant torque and control to riders, now seems to be transferred to motocross. From this patent application, it can be deduced that Yamaha is allegedly exploring innovative solutions to provide extra torque when needed.
One of the main innovations is the integration of a torsion damper in the transmission. This device, consisting of two rotors connected by springs, would act as an energy accumulator, providing a brief burst of extra force to the rear wheel in situations of rapid acceleration.
This would represent a notable change from the traditional motor and clutch setup used in the TY-E. The goal is to improve the feeling of acceleration and provide optimized performance without adding excessive size and weight to the transmission line. The patent illustrations suggest possible developments in the design of Yamaha’s future electric motocross bikes, and we can even speculate on the use of a carbon fiber monocoque frame similar to the one used in the TY-E.
