Description BRP Threaded Bar Inserts are a more secure mounting system for aluminum handlebars using wrap-around style enduro hand guards. They are sold either as a self install kit that includes two threaded inserts and one 5/8-11 tap OR and as the inserts alone for those of you that already own the tap. BRP inserts install with a common hex key wrench and can be transferred from one bike to another. The basic concept of tapping the handlebar to accept the threaded insert works like a charm. By limiting the depth of the tapped handle bar you can firmly bottom out the threaded insert preventing them from loosening. The throttle side insert is 1/4" longer to accommodate the throttle tube. The threaded bar insert is the most solid mount on the market at this time and outperforms anything else. Special Notes We recommend using red loctite on the insert to prevent it from coming loose. Azonic double wall and Renthal Twin Wall handle bars are a larger ID than other aluminum bars and these inserts DO NOT fit these bars. These are the only 2 bars we have found that are not compatible at this time.
