Key Features

• Enhanced Durability: Manufactured from high-quality hardened materials to maximize resistance against "pitting" and metal fatigue, significantly extending the service life of your transmission.
• Precision Meshing: Effectively improves gear meshing accuracy, which reduces internal vibration and noise while preventing gears from slipping or "popping out" under load.
• Stable Power Delivery: Ensures a more stable and reliable transfer of torque from the engine to the drive chain, improving the overall riding feel and vehicle control.
• Cost-Efficient Maintenance: Designed for straightforward installation; clear dimensional accuracy allows for a replacement process that saves on professional mechanic labor costs.
• Smooth Operation: The precision-ground surface reduces friction between the gears and the spindle, allowing for smoother shifts and better thermal management inside the gearbox.
