Abstract: The apparatus has two tilting wheels which, when attached to a two-wheeled vehicle such as a motorcycle or a scooter, allows the vehicle to tilt into a curve notwithstanding the addition of the two wheels. The apparatus includes a frame, a pair of wheel supports and a pair of wheels each rotatable about a separate wheel support. A pair of links interconnect the frame with the wheel supports. The apparatus includes a rocker pivotally connected to the frame and a pair of transverse arms each pivotal about a separate wheel support and the rocker. Each transverse arm has a coil spring for biasing the wheel support and rocker apart. When a vehicle equipped with the apparatus rounds a curve, the frame tilts in the direction of the curve with like tilting of the wheels of the apparatus.
