Upgrade your CVT system with Dr. Pulley Sliding Roller Weights. Unlike traditional round weights, these uniquely shaped sliders allow the variator to open wider, increasing top-end speed, while providing a more aggressive response off the line.
Crafted from a proprietary self-lubricating nylon composite, these weights are designed for maximum longevity, high-temperature resistance, and reduced friction.
Don't see your engine listed? If the engine code includes "QM" or "FM" and displacement is 49�80cc, this part is compatible.
Dr. Pulley is a Taiwan-based manufacturer and the industry standard for sliding roller weights. Their sliders are trusted by scooter tuners worldwide for consistent performance gains and exceptional durability over standard OEM rollers.
Note: Performance tuning parts are intended for racing and off-road use. Professional installation and belt inspection are recommended when changing weights.
