torque spring MALOSSI K13.6 / L75mm yellow for Beta, Kymco, Malaguti

Reinforced counterpressure spring for the rear Malossi convertors. Increased pressure on the drive belt for less slip. Ideal for tuned engines or slipping belts. Straight swap with the original.
Unfortunately, Malossi does not give any indication of percentage change in relation to the OEM spring on Maxi scooters. However, Malossi indicates the spring stiffness (K) and the length of the spring. Thus, the springs can at least compare with each other. In principle applies to Maxiscooter:
1. green springs are softer than the OEM spring
2. all other springs are stiffer than the OEM spring
2. the higher the (K) value, the stiffer the spring
3. at the same (K) value, the longer spring is stiffer
