Yamaha Electric Motocross Bike Could Soon Turn Into Reality, Prototypes Likely To Make Public Appearance Soon

Yamaha Motor India, a renowned two-wheeler manufacturer in India is planning to enter into the electric two-wheeler segment, as it has recently filed a patent for an electric motocross bike.

The introduction of this electric motocross bike has been backed up by the success of the brand’s TY-E trials electric bike. This patent application primarily focuses on designing the transmission to improve traction and enhance torque, specifically catering to the demands of competitive motocross riding.

The patent illustrations offer a glimpse into Yamaha’s potential design for its electric motocross bike, hinting at a carbon fiber monocoque chassis similar to the one used in the TY-E to house the battery. It is not yet known when Yamaha will be introducing the electric motocross, however it is likely that Yamaha may show a prototype model in the coming months.

During testing of the TY-E, Yamaha realized that the direct connection between the electric motor and the rear wheel didn’t provide the necessary drive. To address this, they introduced a flywheel and a conventional clutch into the system, which improved low-speed balance and provided instant propulsion when the clutch was engaged. However, this setup might not be suitable for a motocross bike, which typically has a larger size and heavier weight. In such a scenario, instant torque and a better throttle response are crucial. Yamaha’s solution appears to be the addition of a torsion damper to the transmission system.

This damper consists of two spring-connected rotors mounted between the electric motor and the transmission. These rotors act as a buffer between changes in motor speed and rear wheel speed, while the springs also store energy. The result is not only immediate power delivery but also smooth acceleration even when the rider is aggressive with the throttle.
