ABSTRACT:
A frame and steering arrangement for a three-wheel vehicle that includes a rigid, open box frame of a durable material. The open box frame includes primary and secondary side rails spaced from each other and joined at opposite ends by a front rail and a rear plate. A plurality of mounting components is provided to mount the vehicle engine on the frame adjacent the front rail. First and second support bars are mounted at lower ends on an upper edge of the primary side rails and the front rail and extend over and forwardly of the front rail of the frame. The first and second support bars at the upper ends are connected to a head tube to mount a front wheel assembly on the frame. A steering assembly is provided having a front steering bar to connect to the front wheel assembly. The steering assembly includes a rear mounting plate pivotal relative to the frame and located rearwardly of the front wheel assembly. A pair of connecting rods of different lengths are pivotally connected between the steering bar and the rear mounting plate whereby the mounting plate is pivotal about an axis laterally offset from the front wheel assembly.
