Hatta fork
Hatta forks were a unique design of forks utilized by Kawasaki motorcycles from 1971 through 1975. These forks allowed the rider to customize the rake, spring tension, and fork length.
Kawasaki models with Hatta forks:
- Kawasaki F7 175cc Enduro (1971-1975)
- Kawasaki F5 350cc "Bighorn" (1970-1971)
- Kawasaki F8 250cc "Bison" (1971-1972)
3 way axle
The bottom of each leg of the forks have two positions for the axle. By placing the axle in the auxiliary position forward of the standard position increased the rake. By rotating the legs 180° so the auxiliary axle position is behind of the standard axle slot, decreased the rake. This gave Hatta forks a total of three positions for the axle.
Spring tension
The spring tension rate and damping was adjustable via an adjusting screw at the top of each leg under rubber caps.
Fork length
The upper and lower triple clamps were designed to permit even more adjustment. Both triple clamps had straight through holes as opposed to tapered at the top. This permitted the fork tubes to be raised or lowered to the rider's comfort.
