The BeadBuster XB-450 is our original motorcycle bead breaker, 1st released in October 2012. With the home mechanic and trail rider in mind, it was specifically designed for difficult-to-remove ATV tires, but we soon realized that it worked just as well on just about every kind of tire there is. No adjustment is needed for different tire/wheel sizes. The portable bead breaker is small and perfect for stashing in your glove box or tool box. Save time, money, and frustration by quickly and easily changing your own tires whenever, and wherever you want.
