In collaboration with our MXS Racing Team, we would like to share our long-standing experience with 2-wheelers of all kinds and suggest this variator kit as we think it is the best combination you can probably go for, and we use it on our test engines and prototypes all the time.
This high performance kit includes:
- Stage6 R/T Variator Oversize MBK Nitro / Booster
- Polini Torque Drive Speed Drive Evolution 3 MBK Nitro / Booster
- Stage6 Racing Clutch Bell "Wing Cooler" d=112mm CPI
- Stage6 Racing Clutch "Torque Control MK II" d=112mm CPI / Generic
- Stage6 R/T Drive Belt Oversize MBK Nitro / Booster
- Polini Fan Wheel "Air Speed Evolution 3" MBK Booster / Nitro
The combination of these components and the way they're complementing one another will optimize and maximize the performance of your engine. As a matter of course, it has to be combined with appropriate primary and secondary transmission, depending on your engine.
This high performance variator kit is ideally suited for MXS GP 90cc cylinders, but can also be used with any other 70cc to 95cc Hyper Racing cylinder.
Mounting this oversize kit requires a standard milling job (which is, as you may know, standard procedure when it comes to oversized variators.
Note: the only torque springs compatible with Stage6 112mm variators are the Minarelli ones!
