A security stand is provided which secures a motorcycle and each of its major, valuable components against theft. The stand does not utilize a padlock or chain either of which can be attacked by acid, quickly supercooled and embrittled by a cryogen, or easily cut with an oxyacetylene torch. The stand does utilize an internal locking means such as a dead bolt, which engages the ends of cross bar pipes necessarily containing cementitious material, which pipes are inserted in passages through a pair of angulated arms. The arms extend upwardly from a base, and, preferably both arms and base are also filled with cementitious material. The angulation of the arms is such that they do not provide a horizontal surface against which a hydraulic jacking means may be biased in cooperation with the base, or ground upon which the base is disposed. The cross bar pipes function as locking members when they are inserted through openings between the frame and engine of the motorcycle and locked in the arms. Plural pipes are preferably used, each of which may be locked with a separate locking means. The stand of this invention, as assembled for use, is simple, requiring an internal, concealed key actuated locking means and only three structural components, namely a base, angulated arms and elongated hollow locking members, and preferably each of the components is filled with cementitious material. The filling of cementitious material provides several functions: (a) it provides a reservoir of heat to counter the effect of a cryogen poured on the locking member, (b) it decrepitates under the intense heat of a cutting torch, (c) it dulls a metal-cutting hacksaw blade, and (d) it provides weight to anchor the structural components of the stand.

A security stand for a motorcycle having a frame in which an engine is mounted, said stand comprising, (a) a base, (b) a pair of arms extending upwardly from said base in laterally spaced apart relationship with each other to accommodate said motorcycle between said arms in an upright position, each of said arms having corresponding oppositely disposed passage means through said arms to slidingly accommodate a locking pipe (c) at least one elongated locking pipe for insertion through an opening between said engine and a frame member of said mtorocycle to prevent removal of said engine from said frame, in which locking pipe a cementitious material is contained, which cementitious material includes physically and chemically bound moisture and decrepitates when subjected to intense local heat, said elongated locking pipe being of sufficient length to bridge the space between said arms and to be inserted in said passage means, and (d) key actuated locking means within at least one of said arms to releasably engage said locking pipe near its end.
