R/T Oversize Torque Rear Pulley- Minarelli


Add to Basket

Oversized Stage6 R/T rear pulley for 50cc 2-stroke scooters using Minarelli horizontal/ vertical engines.

The Stage6 Oversize CVT. Different from conventional torque drivers that are manufactured from steel, this part consists of forged aluminium halves that are screwed to a guide piece. The halves have been CNC-machined, which guarantees high precision, especially of the surface angle. Special attention has been paid to ensure an ideal surface roughness, as this has major influences on shifting characteristics. At the end of the manufacturing process, the surface structure is protected by applying a thick ceramic coating, so that the surface characteristics can be preserved as long as possible.
Advantages of the modular construction include the reduced heat built-up, the noticeably lower weight and the possibility to replace individual worn components.

The CVT uses a guide piece with 38/41° angles. Other guide pieces with angles of 39/42° or 37/40° are separately available. This feature is also something new for a CVT system.

Using this oversize torque-driver only makes sense in conjunction with an oversize variator and an oversize drive belt. Stage6 recommends using the respective R/T products, but the torque driver can also be used with products of other manufacturers.
