ABSTRACT:
A fork structure for a motorcycle in which the steering column is connected to the wheel axle so that while it is free to move longitudinally on shock mounts, it is constrained against any significant rotatable motion relative to the axle, thereby minimizing bushing wear and providing tighter response in the steering control. The front end forks of a motorcycle are formed by a pair of tubular members which are rigidly attached to the steering column. These tubular members have slots formed near their bottom ends, these slotted portions being fitted over the opposite ends of the cycle axle. Shock mounts are mounted within the tubular members. The shock mounts include a lower cylindrical bushing which is fixedly attached to the axle and a shock absorber mounted above the bushing with one end of the shock absorber being attached to an extension which is attached to the top end of the tubing. A spring is mounted between the lower bushing and the top end of the tubing, there being an adjustment screw above the spring for adjusting the tension thereof and thus the spring action of the mount.
