Honda Dio SP Polini clutch springs

Kit of 3 Clutch Spring Games Original

Tuned engines begin to develop their power in most cases from a very high number of revolutions, and the engine loses power at a low number of revolutions. This is often noticeable when the motorcycle starts poorly.
To bridge the number of revolutions when the engine has little power, Polini offers this set of replacement springs with different strengths for standard clutches.
