Clutch spring Piaggio Bravo / Boss / Ciao 50cc red +35% Malossi

The hardness of the clutch spring determines whether the mechanism opens the clutch to engage the clutch bell at higher or lower engine revolutions.
A harder spring will make the clutch "engage" at higher revolutions and consequently the bike will start faster from a standstill and you will notice a better acceleration, i.e. a soft spring is as if you start in "second gear", a hard spring is as if you start in "first gear". Be careful with your choice because if it is too hard, you need more power and more RPM to start from a standstill.
Malossi springs are made of steel with high carbon content silicon alloy, heat treated to resist high temperatures better, and do not lose power at high temperatures and with use.
