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 sport touring, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, increase bottoming resistance. Crucial is 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 respective vehicle. If desired, in special cases, individual tuning can be achieved by altering the air chamber.
For motorsport applications, we recommend the very lightweight linear chrome silicon fork springs from Wilbers, which were co-developed with 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 an abrasive media specifically designed for this application 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, 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 regarding the grade 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 on the front wheel.

Note: please order the fork oil separately.
