Reinforced sport back pressure spring from Malossi for Yamaha Majesty and X-Max 400 maxi scooters. The back pressure spring slightly increases the power rpm and improves acceleration performance. The engine shifts smoother and runs smoother.
Useable for the original variator or in conjunction with a tuned variator such as the Malossi Multivar.
.Unfortunately, Malossi does not specify for Maxi scooters, to what extent the pressure changes compared to the OEM counterpressure spring. However, the spring hardness (K) is specified and the length of the spring. Thus, the springs can at least be compared with each other. In principle, the following applies to large scooters:
1. green counterpressure springs are softer than the OEM spring
.2. All other springs are harder than the OEM spring
.3. The higher the (K)-value, the harder the spring
.4. If the (K) value is the same, the longer spring is harder
