Pro Taper’s Twister throttle tube is constructed from quality anodized billet aluminum. The sealed radial ball bearing and polymer bushing allow for a consistent and smooth throttle operation while a knurled grip mounting area ensures a vice-like grip bond.

Features:

• Precision CNC machined
• Sealed ball bearing virtually eliminates friction
• Plastic plug on end to prevent glue and dirt from getting in the bearing
• Knurled finish to provide a solid bond between tube and grip
• Other handlebar brand inserts available
• Twister Throttle Tubes are compatible with all Pro Taper handlebars and Renthal 7/8" handlebars with the standard bearing insert
