Clutch spring Kymco AK550 ie 4-Stroke euro 4 Malossi

Variator spring in lilac colour for Kymco AK550.

The hardness of the variator pulley 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. In other words, a soft spring is like starting in "second gear", with the stiff spring it is as if you are starting in "first gear",

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

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.
