(fork oil must be ordered separately)

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, we generally recommend a progressive fork spring to optimise response behaviour and increase bottoming resistance. Crucially, combine the "Zero Friction" fork springs with the specially developed Wilbers fork oil and observe the correct air chamber for the respective vehicle. If desired, individual tuning can be achieved in special cases 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 components to be processed, such as Wilbers fork springs, are placed together with an abrasive body specifically designed 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 body, and through constant rubbing, lead to a smoothing of the componentupper surface. The result of this process is a fine, glossy surface.
For Wilbers fork springs, this reduction in surface roughness means minimising friction = ZERO friction.

Each set of fork springs includes a recommendation for the viscosity of 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.
