Our Twister Throttle Tube is constructed from premium-quality anodized billet aluminum. The sealed radial ball bearing and polymer bushing provide smooth, consistent throttle twist action, while the surface knurling ensures a viselike grip bond. Using the standard bearing insert, Twister Throttle Tubes are compatible with all ProTaper handlebars, as well as Renthal ⅞" models.
Since 1991, ProTaper has lead the way in premium control
components. We pride ourselves on providing an exciting, innovative, and
complete product line to fulfill the needs of professional racers and weekend riders alike. Through revolutionary ideas like the oversized 1⅛" handlebar and the Micro Handlebar Kit—the only control system purpose-built for youth riders—ProTaper continues to push the limits and transform how we experience riding our motorcycles.
