The compression spring plays an important role in the optimization of mopeds and motorcycles, especially when using more powerful cylinder kits. The springs described here are made of high-carbon silicon steel for increased durability and reliability, and they are painted with heat-resistant paint to withstand the high temperatures encountered during use.
Function and important aspects:
- The spring is located in the rear drive package and affects the response of the variator by adjusting the pressure on the drive pulley.
- With increased power from, for example, a cylinder kit, the drive belt may start to slip, and then a stronger counter-pressure spring may be necessary to handle the increased torque.
- However, it is recommended to only replace the counter-pressure spring if absolutely necessary, as a spring that is too hard can lock the drive belt and increase wear, reducing the efficiency of the drive package.
Available springs and hardness levels:
-
White feather: Reinforced feather, suitable for lighter trimmings.
- Outer diameter: 53.2 mm
- Inner diameter: 45 mm
- Wire diameter: 4 mm
-
Yellow spring: Heavily reinforced spring for engines with greater performance increase.
- Outer diameter: 53.2 mm
- Inner diameter: 45 mm
- Wire diameter: 4 mm
-
Red spring: Racing spring for heavily tuned engines.
- Outer diameter: 53.8 mm
- Inner diameter: 45 mm
- Wire diameter: 4 mm
Choosing the right spring is crucial to achieving optimal performance while minimizing wear on the drive belt.
