Broken Throttle shaft, no problem! Fits X1s, S3 1999+ and 2003 XB9 Buells. The factory shafts were made from soft brass that is prone to breakage, these new shafts are machined from 303SS which is much stronger. Even if its not broken yet, replace it to save you from grief....and a stuck throttle, down the road.
Stainless Steel Throttle Shaft Buell X1,S3 and 03' XB9
We recommend you install the tiny M4 screws with Red Locktite 271, might seem overkill but its amazing how much damage a M4 screw can cause going through an engine.
