Stage6 R/T Torque Drive pulley zuma

Stage6 R/T Torque Drive Oversize by renowned German manufacturer Stage6.

It is CNC-milled from HQ aluminium and has a special ceramic coating to preserve surface characteristics for optimum grip.

It is an Oversize torque driver, meaning it has a larger diameter than the original one.


One of its stand-out technical features is the fact that it has 2 different slots (38° and 41° gradient) for adjusting pulley opening angle. Moreover, the pulley halves are attached to the cam with screws. This modular construction has the advantage of reduced heat build-up and the possibility to replace individual components. This way you can, for example, decide to swap cams, and go for a cam with different angles for different pulley opening angles and speed.
