Stage6 Pulley / Drive Face
Stage6 Pulley / Drive Face Racing without star washer 13mm Minarelli / China 2-stroke scooters, racing drive face with optimized angle.
To save money, original pulleys are usually made from cast or – even worse – pressed steel. When cooling down after production, the discs haven’t found their final shape yet and the drive face angles end up slightly different. Since racing engines have a very narrow power band, these tolerances have direct, usually negative consequences on performance.
In contrast, the Stage6 Racing pulley is precision CNC machined from billet.More than twelve different versions were tested to find the optimal angle. The high quality aluminium alloy and a special low-friction surface coating make cooling fins unnecessary. Made of CNC aluminum, the surface is completely smooth due to CNC-machining, offering an improved finish and better performance.
The pulley is lighter than the stock part, so your variator will perform better and more power will be transmitted to the rear wheel. This racing drive was actually developed for drag races, but is very commendable for regular racing bikes as well.
If you still want to cool the variator optimally, you can use a ventilated Extreme Cut CVT cover from STR8 (only for Yamaha Aerox).
