1" handlebar with a laser-engraved Thrashin® logo. Includes holes for internal wiring and Throttle-By-Wire, allowing installation on newer motorcycle models. For motorcycles with a throttle cable, the TBW cap for the handlebar is required. Ribbed for maximum clamp grip and made in the USA. Requires the use of Thrashin Risers. Street Glide (FLHX) models require the Street Glide Riser adapter plate (0602-1249).
