ABSTRACT:
This disclosure relates to apparatus for preventing the nose dive produced when a motorcycle is sharply braked. The motor cycle includes a frame, front and rear wheels, and front and rear mounting means for connecting the wheels to the frame. The anti-nose-dive apparatus includes a generally U-shaped torsion bar having a center portion and front and rear arms. The center portion is rotatably mounted on the frame, the front arm is connected to the front mounting means, and the rear arm is connected to the rear mounting means. When the vehicle is moving and is sharply braked, the front end of the frame tends to move down relative to the front wheel. This action twists the torsion bar causing the rear mounting means to tend to rise. The reaction on the torsion bar causes the rear end of the frame to move down relative to the rear wheel, thereby reducing the amount of the nose dive.
