Expect better performance from your scooter, period. No matter what stage you are in upgrading your scooter, simply add Dr. Pulley weights and a kevlar belt for a power upgrade.

Dr. Pulley roller 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.

-Made of unique material
-Low Friction/Low Wear/High temperature resistance
-Aluminum compatible
-Fastest roller weights available

Tuning Tips:
Light rollers are good for quick acceleration, stop and go riding and hills, but you loose top end speed.

Heavy rollers will give you a higher top end speed (long roads) but you will loose low end acceleration.

If you’re a heavy person (and/or) if you have a stock motor you will want to lean towards the lighter rollers. If you are a light person (under 140lbs) or you have a big bore you will want heavier rollers.

Perfect for use on genuine 50cc scooters including the Buddy 50 and the Rattler 50.
