Our T-Rex Billet Throttles are a direct replacement for Cobra, KTM, Husqvarna, and Gas Gas. Made from billet aluminum with a sealed bearing cable pivot and a one piece billet aluminum throttle tube. These throttles reduce hand fatigue, and are smoother and stronger than factory throttles. The removable safety window allows for easy carburetor service and quick cable inspection. Thousands of hours testing and developing this high performance throttle. AMA legal in most classes.
