Scooter clutch rollers .. | return |

Standard replacement clutch or variator rollers.

Due to rotation the weight of the rollers become centrafugal force, the higher the rollers weight, the lower the gear change time and the engine works at lower RPM and vice versa.

Variator calibration: To optimise your engine’s performance, adopt rollers that in operation maintain the engine in the highest power rotation regime. By diminishing the roller weight the engine rises in RPM, by increasing weights the engines RPM will decrease.
