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.

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.

  • First-ever clamp-on thumb throttle conversion for twist assemblies

  • Direct fit over OEM throttle tube

  • Minimal modification required (shorten throttle tube)

  • Fully adjustable thumb paddle for personalised ergonomics

  • Compatible with 22 mm ATV-style grips for a uniform bar feel

  • Smooth rotational actuation designed for precision control

  • CNC-engineered for strength, durability, and long-term reliability

  • Works with all switchgear setups: road, race, compact units, OE housings

This system is designed to work with generic twist throttle assemblies, including:

  • OEM motorcycle throttles

  • Aftermarket twist housings

  • Road/race switchgear units

  • Supermoto and motocross throttle housings

If your setup uses a traditional 22 mm handlebar twist throttle — this system is compatible.

What’s Included

  • 1 × RaceTorx Thumb Throttle Assembly

(ATV 22 mm grips recommended; grips not included)

Installation Notes

  • Throttle tube must be reduced by ~75% of its original length

  • Ensure clean, burr-free cut before installation

  • Suitable for both cable-operated and electronic housings (throttle tube dependent)

  • Always test operation before riding
