Contrast spring -POLINI Evo-Slider- Piaggio 800-850cc V-Twin Injection (M554M, Gilera GP 800)

Description

Polini reinforced counter-pressure spring including slider.
The reinforced counter-pressure spring increases the contact pressure on the V-belt, preventing any slippage. The working speed is adjusted by the spring force of the converter and the centrifugal weights mounted in the variomatic. The stronger spring raises the speed level. Thus the engine runs constantly at higher speeds, which is very convenient for sporty drivers, as the engine is more lively and always works at full power.

The plastic slider prevents torsion of the spring, which improves the efficiency and the shifting behaviour of the converter.
