Contra spring Malossi white K8.9 / 130 mm – Piaggio / Aprilia / Gilera 500cc

Description

Malossi reinforced contra spring is designed for 500cc maxi scooters and is an excellent choice for tuning engines. It ensures proper belt tension, prevents slipping and allows better power transfer to the rear wheel.

Using a stronger spring improves acceleration and transmission stability, which is especially important for modified engines or under higher loads.

Malossi indicates spring stiffness with a K value – the higher the value, the stiffer the spring. The white spring (K8.9) is among the stiffer options and is suitable for more powerful setups.
