Dr. Pulley 25x15mm Sliding Roller Weights - Set of 8 for Scooters & Mopeds

Dr. Pulley Sliding Roller Weights for Yamaha, Kymco, Peugeot, and SYM Scooters

These Dr. Pulley 25x15mm sliding roller weights are built for a range of scooters and mopeds, aiming to enhance how the machine performs. The set contains eight weights that work with the variator system to support quicker acceleration and a higher top speed. They suit riders looking to fine-tune engine output, and they sit among our scooter variators & roller weights.

Key Benefits

The sliders use a patented layout that permits the variator to travel further, which changes the gear ratios. In practice this means a more immediate response when you twist the throttle and a more efficient way of holding speed compared with standard round weights. The PA46 composite body is self-lubricating, which contributes to a longer working life by limiting wear on the parts.

Fitting Notes

When swapping out your current roller weights, check that the Dr. Pulley sliders are seated the right way round so the logo faces the correct direction. If you are adjusting performance, you can go for a weight that is 10-15% lighter than the factory part to improve acceleration, or keep to the stock weight if top speed is your priority.
