Variator Stage6 Sport pro Mk 2
The Sport Pro MK2 is the new and improved version of the popular Stage6 Sport Pro variator. This updated, performance-tuned variator delivers better power transmission and smoother shifting behavior.
MK 2 Upgrade - What's new
- Switch to modern roller format (19x15.5mm, 7g) for better performance and durability
- Hard-coated backplate and roller tracks for increased longevity and stable performance at high RPM
- Uncoated sliding surface improves friction and thus performance. Prevents chipping seen in hard-chromed surfaces, reducing wear and belt damage
The ideal variator for stock and sport setups up to 70cc. Comes complete with drive boss, torque plate, rollers, and medium counterpressure spring. Pre-tuned for use with 50cc cylinder and Stage6 Pro Replica exhaust – if your setup differs, you might need to adjust roller weight or spring rate.
Stage6 Sport Pro clutch
The matching Stage6 Sport Pro clutch is known for its durability and reliable engagement. This adjustable 3-shoe clutch can be fine-tuned via different clutch springs and two engagement positions. Reinforced clutch ring and bolted forged pins support the heavy-duty linings.
To ensure ideal power transfer, we’ve included the Stage6 PRO drive belt – optimized grip, long service life, and consistent performance.
Scope of delivery Stage6 variator + clutch + V-belt
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.
