Polini Hi-Speed Variator – Performance CVT Upgrade

The CVT (Continuously Variable Transmission) is responsible for transferring your engine’s power efficiently across the rev range. The Polini Hi-Speed variator is a high-quality upgrade designed to optimize this process, offering better acceleration and higher top speed at an excellent price-to-performance ratio.

The Hi-Speed’s roller tracks have been re-engineered for smoother shifting and improved power delivery compared to previous versions. With the correct roller weights, you’ll experience quicker acceleration and a noticeable increase in top speed.
We recommend experimenting with different roller weights to fine-tune performance to your setup.

The variator works with a standard-size drive belt, but for maximum reliability, we recommend using a reinforced belt. Ideal for 50cc sport and racing engines, this Polini Hi-Speed CVT ensures that your scooter runs at peak efficiency.

Includes:

• Variator with 16x13mm roller weights
• Reinforced contra spring
• Spring seat

Recommended for:
50cc sport / racing setups
