The Motorcycle/ATV Flip Adapters are designed to enlarge or decrease the clamping range of most tyre changers. The Motorcycle/ATV Flip Adapters are installed over the existing turntable clamping jaws to INCREASE the EXTERNAL clamping range of the turntable jaws for motorcycle wheels. The adapters can also be flipped around to DECREASE the EXTERNAL clamping range of the turntable for ATV wheels. The jaws are manufactured from a high density polymer that eliminates the need for optional plastic jaw protectors. These NON-MAR jaws will not damage expensive chrome wheels (if used properly). The height of the Motorcycle/ATV Flip Adapters clamping jaws allows the wheels to be elevated above the solid wheel clamp turntable. This elevation will allow many rear wheels to be clamped effectively (for the purpose of mounting or demounting a tyre) WITHOUT the need to remove sprockets or hubs. The handy Motorcycle/ATV Flip Adapters are secured to the existing steel jaws (on the turntable) with a locking pin that ensures a positive clamping action by the jaws.
