Newly added to our website are the Dr. Pulley Sliders for various scooter applications. Vespa, Honda, Yamaha and most Asian scooters are all in stock. Dr. Pulley Slider weights are the most advanced weights available. 
These sliding rollers perform better than standard round weights by 
allowing the variator to open farther for higher top speeds, and last 
longer with less performance material loss. The weights have several 
unique features such as their composite material containing nylon for 
better performance.
