Description
Malossi presents the springs for Minarelli Horizontal and Derbi Variant Star 3/5 engines.
The stiffness of the contrast spring plays an important role in the transmission of power from the engine to the rear wheel.
It exerts counter pressure on the rear pulleys and therefore has a considerable influence on the operation of the variator. The contrast spring is usually stiffer if the belt tends to slip, if the variator does not work at the optimum RPM level or if the engine is still running below the optimum RPM despite light weights. What has a negative influence on engine performance is a bent contrast spring.
Malossi spr ings are made of high-carbon silicon alloy steel, heat-treated to withstand high temperatures better, and do not lose their properties at high temperatures or with use.

Hardnessof the spring:
White: 30% harder origin
Yellow: 35% harder origin
Red: 40% harder origin
attention! For Derbi Start / 3 / 5 models it is only adaptable if the Minarelli Horizontal scooter pulleys are mounted.
