Why Riders Upgrade

🚀

Maximum Power Transfer
The Stage 4 setup is engineered to put every horsepower your turbo makes to the ground — no slipping, no wasted energy.

🌡️

Cooler Belt Temps
Especially critical if you're running larger tires or paddles — reduced heat means longer belt life and fewer trailside breakdowns.

⚡

Instant Throttle Response
Feel the difference the moment you hit the gas. Crisp, immediate engagement that stock clutching simply can't match.

🎯

Adjustable for Your Setup
Running stock tires or 35s? Trails or dunes? The adjustable weights let you dial in engagement to match your exact build.
