Pulley / Drive Face Stage6 CNC Racing Drive Minarelli

Stage6 CNC RACING Drive pulley for Minarelli

Stage6 CNC RACING Drive pulley for Minarelli, racing pulley with an optimized pulley angle.

For cost reasons, original pulleys are usually cast or, in the worst case, pressed from steel. As they cool, the pulleys can spring back slightly, resulting in measurable differences in the pulley face angle. On racing engines with their narrow usable rpm range, such deviations directly affect performance.

The Stage6 racing pulley is precision CNC-milled from solid material. More than 12 different versions were tested before the optimal angle was determined. The use of a high-quality aluminum alloy and a special surface coating eliminates the need for cooling blades. The reduced mass also has a positive effect on rear-wheel power. The pulley was designed for drag racing, but it can also be used on regular racing scooters.

For optimal CVT cooling, a vented Extreme Cut variator cover from STR8 is also available (for Yamaha Aerox only).
