Description: - The seamless twist-and-go experience of the RayZR is powered by its precision-engineered B2U9 Transmission assembly. At its core are the Main Axle Comp. and Axle Drive, which work alongside the Gear 1st Wheel to deliver torque efficiently to the rear tire. To ensure near-silent and friction-free operation, the kit utilizes high-performance Bearings and Oil Seals that prevent lubricant leakage and internal contamination. Every Circlip and secondary bearing is matched to the millisecond of rotational timing required for smooth acceleration. This transmission system is built to withstand the high-heat, high-friction environment of the CVT case, ensuring your scooter doesnt lose power over time. Genuine Yamaha transmission parts offer the technical clarity that only factory-balanced gears can provide, eliminating the whine and vibration common with inferior spares. For the rider, this means purchase confidence in every green-light start, knowing your RayZR’s driveline is optimized for peak mechanical performance and urban longevity.
