A vehicle that includes a vehicle body and a vehicle support assembly. The vehicle body has a longitudinal axis and is configured for supporting a rider thereon. The support assembly includes first (421A) and second (421B) tilting wheels disposed respectively at different lateral positions with respect to the longitudinal axis, a tilt-mechanism (452) supportively associating the vehicle body from the tilting wheels to enable the vehicle body to tilt through a first tilt range with respect to a surface on which the tilting wheels are disposed, and a tilt-limiter (456) operably associated with the tilt-mechanism (452) to restrict the tilting of the vehicle body to less than the first tilt range, and releasable to allow the tilting through the first tilt range.
