Abstract: A motorcycle uses a unique suspension system to reduce front end dive during braking. Anti-dive characteristics through full suspension travel provides a smoother ride by reducing the compression damping used in the suspension. The suspension system incorporates a rigid fork, a compression fork and a rocker arm. The front wheel is mounted to the rocker arm such that an axis of the wheel is located along the rocker arm between the rigid fork and the compression fork. A brake is coupled to the axis of the front wheel with a first support member and is connected to the rigid fork with a second support member. A brake linkage which includes a portion of the rigid fork, the rocker arm, and the first and second support members forms an irregular quadrilateral during vertical movement of the front wheel, such that a centerline of the second support member and a centerline of the rocker arm intersect behind the front wheel axis.
