Abstract

Abstract A kickstand for attachment to a frame of a motorcycle or the like and of the type adapted to swing selectively into a first position along the side of the motorcycle and to a second position extending downwardly from one side of the frame to contact the ground so as to support the motorcycle frame in an upright position. The kickstand includes a tubular member having one end releasably clamped to the motorcycle frame, while the other end telescopically engages a support rod which is positionally adjustable along the length of the tubular member such that the overall kickstand length may be longitudinally adjusted for use with motorcycles of varying sizes. The kickstand includes a novel theft prevention clamping device.
