A sensible tool for motorcycle chain and wheel work. Non-skid backing keeps the steel frame in place and aluminum rollers with sealed ball-bearings allow you to smoothly rotate for chain maintenance, tire inspection and cleaning. For bikes up to 650 lbs. Small and lightweight enough to stow under a seat or in a tank bag for on-the-road use. For road bikes only, not for off-road tires. 4"×4.5", 1.25 lbs.
