Product details

Wilbers fork spring set, progressive, for Kawasaki Z900RS, Type ZR900C, model year 18- (fork oil to be ordered 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. In touring and touring-sport applications, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. Very important is the combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the respective vehicle. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very light 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 located together with a grinding media specially adapted for this purpose in a vibrating container, the so-called trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the grinding media and, through constant rubbing, lead to a smoothing of the part surface. At the end of the process, there is a fine, shiny surface.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring set includes a recommendation regarding 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 front wheel.

Note: please order the fork oil separately.
