The Black Widow Motorcycle Bead Breaker tool is a fast and efficient way to break sport tire beads in the garage or shop. Most motorcycle, ATV, or sport wheels with 16" rims or larger fit over the top 15-1/2" diameter ring and are secured through the core by a 9-1/4"H x 1/2"D rim mount bolt with a wing nut. This core rim mount also keeps the tire at an even position when rotated during the bead popping process. Works great as an ATV bead breaker too! A knob-adjustable 5" wide by 1/8" thick breaker tool is fixed to a long 29" handle for the extra leverage required to break older, rusted or heat fused tires, and bead-lock ATV wheels. The BW-2063 bead breaker tool also comes with (4) white plastic rim protectors evenly spaced with the tire cradle supports. Made with heavy duty reinforced steel. The handle support and frame is finished in a durable glossy black powder coat while the breaker handle and core mount features a zinc finish. Includes a 1 year Manufacturer's warranty.
