Product Information

Full details

The Domino HR Cross 50 mm throttle control (2203.03-02) is a high-performance component engineered for off-road riders and enthusiasts looking to sharpen their bike's acceleration response. It provides precise, reactive control through a 50mm travel design and a calculated 1.9 degrees per mm multiplication ratio, resulting in predictable power delivery across varied terrain. While this throttle offers exceptional control for aggressive riding, it is a technical component that requires mechanical proficiency for proper installation and cable adjustment.

Extended Product Information

FAQs

Is this throttle universal?

While designed for off-road performance, it is a universal-fit component, but it requires compatible cables and sufficient space on your handlebars.

Does it come with cables?

No, the Domino HR Cross 50 mm throttle control is typically sold as the housing and tube assembly only.

What does the 1.9 degrees per mm ratio mean?

It refers to the pull ratio of the throttle. For every millimeter the cable is pulled, the throttle plate or slide opens by 1.9 degrees.

Can I use this on a street bike?

It is optimized for off-road/cross use. While it can be installed on other bikes, the pull ratio may change how your throttle behaves compared to a street-specific design.

How do I maintain the throttle mechanism?

Keep the housing clean of mud and debris. Periodically inspect and lubricate the cables to ensure smooth movement.

Troubleshooting

Throttle does not snap back to closed

Check if the throttle tube is rubbing against the handlebar end or grip. Ensure cable routing has no sharp bends.

Excessive free-play in the grip

Adjust the cable tensioners at the throttle housing or at the carburetor/throttle body end to remove slack.

Pros and Cons

Pros

  • Improved throttle sensitivity and response
  • Precise 1.9 degrees per mm ratio for better power modulation
  • Sturdy construction suitable for off-road conditions
  • High build quality from a reputable performance brand

Cons

  • Requires mechanical installation experience
  • May require cable adjustment or replacement to match specific bike models
  • Not intended for casual street riding setups without modification

Setup, Compatibility & Care

Installation requires basic mechanical knowledge and access to your bike's throttle cable housing. Ensure that you have the correct throttle cables compatible with the Domino housing geometry before installation.

  1. Remove the existing throttle housing and cables.
  2. Mount the Domino HR Cross unit to the handlebar, ensuring enough clearance for levers.
  3. Route your throttle cables through the housing and connect to the internal pulley.
  4. Adjust cable tension so there is a small amount of free-play at the grip, ensuring the throttle snaps back to the closed position immediately when released.

Regular maintenance involves checking for cable fraying and ensuring the internal pulley mechanism remains free of dirt and debris. A light application of high-quality dry lubricant can be used if the action feels stiff.
