Description
Description
The gear ratio in scooter transmissions is changed by the inward & outward rolling movement of the roller weights. This size of 25x15 sliding roller weights is compatible with larger sized scooters, including several models from Yamaha.
With the innovative Dr. Pulley sliders, the roller weights ?Ç£slide?Ç¥ in and out in the Movable Drive Pulley (MDF) to change/extend the gear ratio.
Lighter roller weights = faster take-off acceleration, lower top speed.
Heavier roller weights = slower take-off acceleration, higher top speed.
