We highly recommend that you begin by upgrading the variator sliding weights before engaging in any performance upgrades. This is the simplest of upgrades and the least expensive. This is a minimal investment and offers a maximum return.

The main rule for tuning variators is the lighter the slider the more rpm's are needed to push the rolls outwards through centrifugal motion to set the gear change in motion. Heavier sliding weights need lower rpm's to start moving.

Heavier sliding weights = slower take-off speed, more acceleration = higher maximum speed.
Lighter sliding weights = faster take-off speed, less acceleration = lower achievable speed.

The right balance is an individual choice since a scooter racer will want heavier weights to achieve a higher overall speed so that they might be faster at full throttle. For daily use a rider might prefer lighter weights for more power to take off faster at stop light.

Dr. Pulley Sliding Weights -- The latest sliding weights to hit the market and the most advanced weights available. These sliding rollers perform up to 20% better than standard round weights and last up to 18% longer with 22% less performance material loss. The weights have several unique features such as their composite material being nylon for faster performance.

Made of unique tribological material SL-9T and SL-9TS (oilless PA46) • Low friction coefficient / Low wear / High temperature resistance • Aluminum compatible; No abrasive fibers (glass fiber or carbon fiber) • Fastest Sliding Weights available
