Dr. Pulley Round Roller Weights are engineered for riders who demand more than what standard OEM parts can offer. Known for their exceptional durability and low-friction properties, these weights are the industry standard for CVT tuning.
Unlike generic rollers, Dr. Pulley uses a proprietary self-lubricating polymer that significantly reduces the risk of "flat-spotting," ensuring your transmission shifts smoothly and maintains its performance over thousands of miles. Whether you are looking for better hill-climbing torque or a higher top speed, these weights provide the precision needed to dial in your scooter's powerband.
Key Performance Benefits
Superior Heat Resistance: Designed to withstand the high temperatures found in performance CVT systems without degrading.
Extended Service Life: Lasts significantly longer than standard nylon rollers, reducing maintenance frequency.
Optimized Power Delivery: Precision-weighted to help you fine-tune acceleration and top-end speed.
Low Friction Material: Provides a quicker, more responsive shift compared to stock weights.
These 18x14mm rollers are the standard size for most 125cc to 170cc 4-stroke scooters using the GY6 engine platform (Engine codes 152QMI and 157QMJ).
