Product details

Wilbers fork spring set, progressive, for Kawasaki ZXR 400, type ZX 400 L, model year 91-99 (please order forköl separately), with ABE according to the usage list

General description

Depending on the application, Wilbers offers progressive or linear forkfedern, manufactured from the best and highest quality chrome-silicon steel. In touring and touring-sport applications, we generally recommend a progressive forkfeder to optimise responsiveness and, on the other hand, to increase bottoming resistance. The combination of "Zero Friction" forkfedern with the specially developed Wilbers forköl and observing the correct air chamber for the correspondinge vehicle is very important. If desired, an individual setup can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very light linear chrome-silicon forkfedern from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the componente to be processed, such as Wilbers forkfedern, are located together with an abrasive medium specially adapted for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container generate a relative movement between the workpiece and the abrasive medium and, through constant rubbing against each other, lead to a smoothing of the componentupperfläche. At the end of the processing, a fine, glossy surface is achieved.
For Wilbers forkfedern, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of forkfedern includes a recommendation for the viscosity of the forköl and the air chamber height in the fork. These values have been determined by experienced Wilbers technicians and ensure optimal riding comfort and feedback on the front wheel.

Note: please order the forköl separately.
