Abstract
A two-wheel-drive sport all-terrain vehicle (ATV) has a front drive geometry in which the scrub radius is zero or negative combined with a low king pin axis angle, which desirably reduces both steering kickback and lateral pull during braking. The scrub radius less than or equal to zero can be achieved by outwardly displacing the king pin axis, which is defined by the upper and lower pivotal joints of the upper and lower A-arms of the front suspension. To displace the king pin axis outwardly, the disk brake and associated caliper are inverted. The disk brake is supported by support arms extending inwardly from the wheel hub. The disk brake includes an aperture to accommodate both the lower pivotal joint, which protrudes through the plane of the disk, and the inverted caliper. The front suspension further includes a knuckle pivotally connected to the A-arms and an integral aluminum spindle. For further compactness, the wheel hub includes angular-contact bearings.
