Domino Racing XM2 Throttle Control System

The Domino Racing XM2 Throttle Control System is the gold standard in cable throttle control for closed-course road racing. Trusted by MotoGP teams, MotoAmerica competitors, and Canadian Superbike Champion Alex Duval, the XM2 is the most widely used throttle solution in professional road racing — and it's available for your build.

Race-Proven Performance

The XM2 ships with three interchangeable pulleys, letting you dial in the exact throttle rotation speed for your application — whether you're chasing lap times or optimizing corner exit drive. The official throttle of Team Hammer and countless MotoGP squads, this system is engineered for the demands of competition, not compromise.
