Torque Drive Kit Polini Speed Drive Evolution Pre Piaggio

Polini Speed Drive P.R.E. Torque Driver – Piaggio High-end oversize torque drive from Polini for optimized power transmission and maximum performance on tuned engines. Why Choose the Polini Speed Drive? In general, an oversize variator or torque driver increases the overall gear ratio range, improves acceleration, and allows for a higher top speed, all while ensuring more efficient power transfer. The movable pulley features two guide slots with different ramp angles (36° and 38°). These are designed to optimize power transmission while maintaining a constant engine speed in the peak torque range. The different ramp angles directly influence the axial force applied to the drive belt, allowing you to fine-tune the CVT response and perfectly match it to your engine setup. 38° grooves (recommended basic setup)For a sporty set-up with strong, dynamic acceleration. Easily identified by the marking point on the side. 36° groovesTo reduce the engagement RPM of the CVT - ideal for earlier power delivery and a smoother response.
