A motorcycle having in-line front and rear wheels, and a pair of outrigger wheels spaced laterally apart at opposite sides of the rear wheel. The outrigger wheels may be extended downwardly to engage the roadway to provide lateral support against overturning, or retracted upwardly when their use is not desired. When extended, they are yieldable upwardly to permit leaning of the vehicle in turns. A control system permits selective use of a first operational mode in which the outrigger wheels are automatically retracted only at vehicle speeds above a pre-set level, a second mode in which the wheels remain extended at all speeds, and a third mode in which the wheels are retracted at all speeds.

A system for stabilizing a two-wheeled self-propelled motorcycle vehicle against lateral overturning, said vehicle having a steerable front wheel and a powered rear drive wheel normally disposed in the same vertical plane, said stabilizing system comprising: a. a pair of outrigger wheels carried by the vehicle frame for vertical movement relative thereto and disposed respectively at opposite sides of said drive wheel in laterally outwardly spaced relation therefrom, b. wheel extension means operable to move said outrigger wheels downwardly into engagement with the roadway surface when their use is desired, said wheel extension means comprising spring means biasing said outrigger wheels to their extended position, and c. wheel retraction means powered by the vehicle drive system and operable when actuated to overcome and reverse the bias movement of said spring means, whereby to retract said outrigger wheels upwardly, said wheel retraction means constituting a fluid pressure system powered by the vehicle power plant and operable when actuated to overcome the bias of said spring means to retract said wheels, said fluid pressure system comprising a compressor operable when driven to deliver fluid under pressure to retract said wheels, an electric motor operable to drive said compressor and powered by the vehicle electrical system, an operating electrical circuit for said motor, and means operable to complete said motor circuit whenever retraction of said wheels is desired.
