A portable motorcycle jack is provided comprising a base arm and a lift arm hingedly joined for folding the two components together. The base arm has a foot that rests co-planar with the ground when in use. The lift arm is hingedly joined to the base arm at base end and has a cradle for engaging the motorcycle at an cradle end. In another aspect, the base arm has a plurality of apertures arranged linearly and sloped relative to the base arm to provide adjustment in length of the motorcycle jack while maintaining the over-fulcrum angle of the base arm relative to the lift arm regardless of which length is selected. |
