Wilbers fork springs for Kawasaki ZX 9 R Ninja 02-

Product Details

Wilbers fork spring set, linear, rate 9.5 kg/cm, for Kawasaki ZX 9 R Ninja, type ZX 900 E, model year 02- (fork oil to be ordered separately), with ABE according to 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 touring sport, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. Crucially, 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, is very important. If desired, in special cases an individual setup can be achieved 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 slide grinding:

During slide grinding, the workpieces to be processed, such as Wilbers fork springs, are located 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 and, through constant rubbing, lead to a smoothing of the workpiece surface. At the end of the process, a fine, glossy 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 regarding 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 handlebar.



Note: please order the fork oil separately.
