Product details

Wilbers progressive fork fork spring set for Kawasaki Z900, Type ZR900B, Model Year 2018- (fork oil to be ordered separately), with ABE according to the application list

General description

Depending on the application, Wilbers offers you progressive or linear fork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and sport-touring, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase resistance to bottoming out. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the respective vehicle is very important. If desired, a customised setup 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 component to be processed, such as Wilbers fork springs, are placed together with an abrasive media specially adapted 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 media, leading to a smoothing of the componentupper surface through constant rubbing. At the end of the processing, a fine, glossy surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of fork springs includes a recommendation for the viscosity of the fork oil and the air chamber height 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.
