Minarelli scooter clutch spring Malossi

Malossi presents the springs for Minarelli Horizontal engines and Derbi variant Star 3 / 5.

The hardness of the contrast spring plays an important role in transmitting the engine's power to the rear wheel.

It exerts counterpressure on the rear pulleys and therefore has a considerable influence on the operation of the variator. The contrast spring is usually harder if the belt tends to slip, if the variator does not operate at the optimal RPM level, or if the engine, despite light weights, continues to run below the optimal RPM. A twisted contrast spring negatively affects engine performance.

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