A stand comprising a pair of plates for attachment to the forward part of the frame of a motorcycle, providing a pair of bushings on a transverse axis through which bearings the cross-bar of a U-shaped assembly is passed. At least one of the plates is further arcuately orificed for a predetermined distance to receive a stop member adapted to move about an arc parallel to the cross-bar and to be stopped by the extremities of the arcuate orifice. A spring connected between a projection on at least one plate and one of the arms of the U-shaped member serves to urge the latter into either a locked extended or retracted position.
