Description
Stage6 Sport Pro variator for 50cc Piaggio Zip
The Stage6 Sport Pro is a high-quality CVT for 50cc four-stroke engines that noticeably improves both acceleration and top speed of 4T scooters. This is one of the most efficient and powerful tuning options for four-stroke engines, that are typically rather limited when it comes to increasing performance.
benefits of Stage6 Sport Pro 4T CVT
Smooth starts: The Sport Pro leads to smooth starts making the riding experience particularly pleasant.
Improved acceleration and higher top speed: Optimized shifting and an increased power level improve acceleration and allow for higher top speeds.
Smooth shifting and mechanical smoothness: Sport Pro ensures smooth shifting and greater mechanical smoothness even at high speeds.
Consistent performance: The system offers consistent performance that a standard scooter cannot offer.
High quality: Extremely resistant chrome coating to reduce friction and wear, for maximum product life.
To further optimize the performance of your Piaggio 4-stroke scooter, we recommend combining the variator with the Stage6 Sport Pro clutch for Piaggio 50 4T from the same series, together with a new clutch bell and a new V-belt. To make the settings easier, you should purchase a tuning set with diffferent 19x15.5mm rollers.

Stage6 Sport Pro
The Sport Pro series from Stage6 consists of various CVT components. The variator, clutch, V-belt and complete kit are designed for sport and racing setups.
Stage6 has revised shapes and materials to improve the performance of the CVT compared to the original and to adapt it to the performance increase after installing a sport cylinder.
scooter CVT
Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.
CVT Parts:
- Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
- Ramp plate: Holds the weights in place.
- Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
- CVT roller weights: Adjustment weights that play a critical role in function and performance.
original, Sport and Oversize CVTs
- Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
- Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
- Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.
You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
