Wilbers forkfedern for Kawasaki Z 900 74-75

Product Details

Wilbers fork spring set, progressive, for Kawasaki Z 900, type Z 1 F, model year 74-75 (please order fork oil separately), with ABE according to application list

General Description

Depending on the application, Wilbers offers progressive or linear fork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and touring-sport applications, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase resistance to bottoming out. The combination of the "Zero Friction" fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the specific vehicle is very important. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very lightweight linear chrome-silicon fork springs from Wilbers, which were co-developed by the Motorsport Team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the parts to be processed, such as Wilbers fork springs, are placed together with an abrasive medium specially designed for this purpose 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 component surface due to constant rubbing. At the end of the process, a fine, shiny surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means minimising friction = ZERO friction.

Each set of fork springs includes a recommendation for the viscosity of the fork oil 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 handlebars.

Note: please order the fork oil separately.
