Wilbers forkfedern for Kawasaki GPZ 900 R 90-

Product Details

Wilbers forkfedern kit, progressive, for Kawasaki GPZ 900 R, type ZX 900 A, model year 90- (forkoil please order separately), with ABE according to application list

General Description

Depending on the application, Wilbers offers progressive or linear forkfedern, manufactured from the best and highest quality chrome-silicon steel. In touring and sport touring applications, we generally recommend a progressive forkfeder to optimise response and, on the other hand, to increase bottoming resistance. Very important is the combination of the "Zero Friction" forkfedern with the specially developed Wilbers forkoil, as well as observing the correct air chamber for the correspondinge vehicle. If desired, in special cases, individual tuning can be achieved by changing the air chamber.
For motorsport applications, we recommend Wilbers' very light linear chrome-silicon forkfedern, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the componente to be processed, such as Wilbers forkfedern, are located together with a specially designed abrasive medium in a vibrating container, known as a trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive medium, leading to a smoothing of the componentupperfläche through constant rubbing. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfedern, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of forkfedern includes a recommendation for the viscosity of the forkoil and the height of the air chamber in the fork. These values have been determined by experienced Wilbers technicians and ensure optimal riding comfort and feedback at the front wheel.

Note: please order the forkoil separately.
