RaceTorx Thumb Throttle – Clamp-On Conversion System
Introducing a world first: the RaceTorx Thumb Throttle, a clamp-on, rotation-controlled thumb paddle system designed to integrate seamlessly with almost any standard twist throttle assembly.
Unlike traditional thumb throttle conversions that require full housing replacements or complex rebuilds, the RaceTorx system mounts directly over the OEM throttle tube. The only requirement is a minor modification to the tube itself.
Simple Installation
To install:
Reduce your existing throttle tube length by approximately 75%.
Slide the RaceTorx Thumb Throttle over the remaining section.
Tighten the clamp.
Fit 22 mm ATV-spec grips on both sides for ergonomic symmetry.
No wiring changes. No housing replacements. No complicated setup.
Designed for Control, Comfort, and Compatibility
The system uses a rotational actuation method, allowing the thumb paddle to provide smooth, progressive control input.
The adjustable thumb paddle ensures the perfect position for any rider, whether for road, race, supermoto, stunt, or off-road setups.
This is the first product of its kind available on the market — engineered for reliability, proven under load, and designed around real-world riding demands.
