Torque spring MALOSSI K9.0 / L100mm red for Aprilia, Benelli, MBK, Yamaha

Reinforced red clutch contra spring from Malossi for the Aprilia Leonardo 250cc, Benelli Velvet, Italjet Jupiter, Malaguti Madison, MBK Skyliner and Yamaha Majesty Maxi scooters, provides better acceleration.

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
3. the higher the (K) value, the stiffer the spring
4. at the same (K) value, the longer spring is stiffer
