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 resistance to bottoming out. The combination of the "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, in special cases, an individual tuning can be achieved 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 components to be processed, such as Wilbers fork springs, are located together with an abrasive body 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 body, and through constant rubbing against each other, lead to a smoothing of the component 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 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.
