Stage6 R/T overrange transmission kit ZUMA

Stage6 R/T Oversize Variator Kit ZUMA For scooters with Minarelli horizontal / vertical engine. This kit will give you MORE top end and MORE acceleration! Its a no brainer, and its a killer price!


Stage6 overdrive R/T transmission kit

The kit includes:

  • Stage6 R/T Oversize Racing Variator with 6 roller weights (19x15.5mm). The angles of the roller tracks and running surface were optimized for smooth linear operation during acceleration. Special attention has been paid to ensure ideal surface roughness to achieve optimum grip, as this has a major influence on shifting characteristics. All CNC parts are protected by a thick ceramic coating, so that the surface characteristics can be preserved as long as possible. The fan wheel (also included) can be removed to reduce air friction during intense use (such as at drag racing).
  • Stage6 R/T Oversize Torque Drive. CNC-milled HQ aluminium torque driver, also sealed with a ceramic coating. The way this torque drive is manufactured and assembled is what gives it its competitive edge. After being milled and coated, the half pulleys are bolted to (not welded to which is standard technique) the hub so the two halves are aligned perfectly. Moreover, it is made of forged aluminium leading to weight reduction and consequently improved heat dissipation. That's what we call state-of-the-art engineering!
  • Stage6 R/T Oversize Drive Belt, reinforced belt developed for Oversize variators
  • Stage6 R/T Torque Spring, purple, for improved acceleration
