BMW C GT 650 ie 4-Stroke Malossi clutch spring

White variator spring Malossi for BMW C GT 650 ie 4T LC / C Sport 600-650 ie 4T LC.

The Malossi springs are made of steel with a high carbon silicon alloy, heat-treated to better withstand high temperatures, and do not lose their properties at high temperatures or with use.

The hardness of the clutch spring determines whether the mechanism opens the clutch to engage with the bell at higher or lower engine revolutions.
A stiffer spring will make the clutch "engage" at higher revolutions and, as a result, the bike will take off faster from a standstill and you will notice better acceleration. That is, a soft spring is like starting in "second gear", with the stiff spring it is as if you start in "first gear",

Attention! In your choice, as if it is too stiff, you will need more power and higher RPM to start from a standstill.
