Stage6 RT Oversize variator kit for Yamaha Zuma
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. It includes the 13mm variator sleeve, but you can order a 16mm sleeve and adapt it to larger crankshafts.
It's perfectly fine to use this oversized variator with standard torque drivers, but to unlock its full potential, we recommend using it with the Stage6 R/T oversize torque drive.
Angles and roller tracks were revised and optimized. The surfaces are treated with a special protective ceramic coating to give it a longer life and to improve performance.
Note: you cannot use your electric starter with this racing variator.
