BRP Threaded Bar Inserts ... are a more secure mounting system for aluminum handlebars using wrap-around style enduro hand guards. They are sold as a self install kit that includes two threaded inserts, two bolts to mount your handguards. BRP inserts install with a common hex key wrench and can be transfered 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 accomodate the throttle tube. The threaded bar insert is the most solid mount on the market at this time and outperforms anything else.
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 compatable at this time.
