Hatta fork
Hatta forks were a design feature of 2 Kawasaki models, the Kawasaki F7 175cc and Kawasaki F5 350cc "Bighorn", and Kawasaki F9 250cc "Bighorn" allowing the rider to adjust the rake and trail of the motorcycle as well as the tension and dampening rate.
3 way axle
The bottom each leg of the forks have two positions for the axle. By placing the axle in the auxiliary position the wheel base can be lengthened one inch. Alternatively the legs could be turned 180° so the auxiliary axle position is behind of the standard axle slot. This gave Hatta forks a total of three positions for the axle.
Spring tension
The spring tension rate and damping was adjustable via rubber caps at the top of each leg.
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.
