Torque spring POLINI +15% Honda 250 -1998, Kymco Grand Dink, People, Xciting 250

Polini springs increase pressure by 15% and are therefore ideal for lightly tuned engines. The springs press the gear on the rear converter onto the belt. They also create pressure to shift the variator. A lighter pressure is required once an engine has been tuned to prevent it from moving into a dangerously high rev range. The pressure of the springs is closely tied to the variator. If a spring is fitted, it must be matched to the variator. Original spring weight: 70/32.5mm/kg. Polini spring weight: 70/37mm/kg. Spring thickness: 4.7mm. Total length: 180mm. Internal diameter: 58mm. Number of coils: 8.
