General Description

Depending on the application, Wilbers offers progressive or linear fork springs, made from the best and highest quality chrome-silicon steel. For touring and touring-sport recommend, we generally recommend a progressive fork spring to optimise responsiveness and increase bottoming resistance. Crucially, the combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil and the observance of the correct air chamber for the respective vehicle is very important. If desired, an individual adjustment can be achieved in special cases 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 media specifically 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 lead to a smoothing of the componentupper surface through 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 set of fork springs comes with a recommendation for 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.
