NR999 Motorcycle Shop Dolly makes it easy to move a motorcycle, dirt bike, or ATV in your shop or garage. Its easy to assemble and the heavy duty steel design can support up to 2500 lbs. Textured rubber grips on the top of the support arms prevent scratching and smooth rolling caster wheels make it easy to maneuver. The motorcycle dolly's legs have three adjustment holes, allowing you to choose an overall height of 10", 11", or 12". To help lift your bike onto the dolly, a jack such as the Black Widow MC-JACK is recommended.
