ABSTRACT:
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.
