ProTaper Yamaha YZ125-YZ250 (All) Twister Throttle Assembly

$82.99

The ProTaper Yamaha YZ125-YZ250 (All) Twister Throttle Assembly is a billet aluminum throttle tube built for Yamaha YZ125 and YZ250 riders, covering a wide range of model years and variants including X-series and special editions. ProTaper anodizes the aluminum and fits the tube with a sealed radial ball bearing and a polymer bushing so the throttle turns smoothly and consistently under your hand. A knurled surface under the grip locks things in place, and a crud plug keeps grip glue out of the bearing.

This assembly replaces your throttle tube and works with all ProTaper handlebars as well as Renthal 7/8 in. handlebars using the standard bearing insert. Every kit includes a free insert for ProTaper bars, so no separate adapter purchase is needed.
