Wilbers fork springs for Kawasaki ZX 9 R Ninja 98-

Product Details

Wilbers fork spring set, progressive, for Kawasaki ZX 9 R Ninja, type ZX 900 C, model year 98- (fork oil please order separately), with ABE according to usage 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 usually recommend a progressive fork spring to optimise response on the one hand and increase bottoming resistance on the other. The combination of the "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the corresponding vehicle, is very important. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend Wilbers' very light linear chrome-silicon fork springs, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers fork springs, are placed together with abrasive media specially adapted for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container generate relative motion between the workpiece and the abrasive media, leading to a smoothing of the componentupper 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 a minimisation of friction = ZERO friction.

Each fork spring set 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 from the front wheel.

Note: please order the fork oil separately.
