Torque spring POLINI +33% for Morini, Suzuki

Polini springs increase pressure by 33% and are therefore ideal for tuned engines. The springs press the gear on the rear converter onto the belt. They also create pressure to shift the variator. Once an engine has been tuned, lighter pressure is required to prevent it from moving into a dangerously high rev range. Spring pressure is closely tied to the variator. When fitting a spring, it must be matched to the variator. Original spring weight: 45/24mm/kg. Polini spring weight: 45/32mm/kg. Spring thickness: 4mm. Total length: 110mm. Internal diameter: 45mm.
