TC Bros. 1" Billet Motorcycle Throttle Tube

Why trust good throttle action to a plastic part? Upgrade your stock or plastic aftermarket throttle sleeve to this billet unit from TC Bros.

CNC-machined from billet aluminum—not cast like others on the market
Knurled finish accepts a huge variety of aftermarket rubber grips and often negates the need for messy grip glue
More durable than plastic throttle tubes
Compatible with common barrel-type cable ends

Flex in the OE plastic sleeve can give crummy throttle feel, and grip glue can sometimes wind up in spots it shouldn't, gumming up the works and yielding subpar throttle response. This tube lets you skip the glue and apply a dab of lube here and there that will give you the slickest throttle money can buy.
