Abstract
A three wheeled vehicle comprises a front subframe having a front wheel journaled thereto and a seat for a rider mounted thereon, and a rear subframe having a pair of rear wheels journaled thereto. The front subframe is journaled to the rear subframe at a kingpin axis, which defines a caster angle with respect to the vertical. The kingpin axis is spaced by a trail dimension from the rear axle axis. The caster angle and trail dimension, together with the wheelbase dimension between the front and rear axle axes and the track dimension across the rear wheels, are chosen cooperatively to define the desired handling characteristics of the vehicle.
