CVT Oversize Stage6 R/T Minarelli / China 2-stroke 13mm stub (Yamaha Aerox / BW's)

Stage6 R/T Variator Oversize Minarelli / China 2-stroke 13mm stub (Yamaha Aerox / BW's) - part of the Oversize CVT kit by Stage6 and best used with the matching oversize torque drive. Enlarged "oversize" CVT systems have become popular for race engines since they extend the range of the transmission and provide improved power transmission.

The roller tracks were optimized for use with R/T engines, for 6 roller weights (19x15.5mm - 3.5g). Shifting and rev characteristics are smoothed and even, acceleration at all speeds is improved. CNC-machined high-precision angles are then given a special ceramic coating that preserves surface characteristics for extended life expectance and optimum grip. Blast cleaning, as is customary for steel pulleys, is not necessary; it only becomes necessary when the coating shows noticeable signs of wear. The centre area of the ramp plate was reinforced and the sintered bushing provides makes for optimal lubrication.

The variator is equipped wit 6 roller weights (19x15.5mm - 3.5g) and comes with a special R/T fan wheel (plastic, removable, for example for drag races) and a reinforced racing torque spring. Special variator holding tools can be purchased separately.

It's perfectly fine to use this oversized vario with standard torque drivers, but to unlock its full potential, we strongly recommend using it with the Stage6 R/T oversize torque drive and oversize drive belt

The CVT comes with a sleeve for 13mm crankshaft stubs; a 16mm sleeve is also available (art. no. S6-56140ET015).
