General description

Depending on the application, Wilbers offers progressive or linear forksprings, manufactured from the best and highest quality chrome-silicon steel. For touring and sport touring, we generally recommend a progressive forkspring to optimise response and increase bottoming resistance. Crucially, combine the 'Zero Friction' forksprings with the specially developed Wilbers forkoil and observe 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 forksprings from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces, such as Wilbers forksprings, are placed together with an abrasive media specifically designed 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, leading to a smoothing of the workpiece surface through constant rubbing. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forksprings, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each forkspring set includes a recommendation for the viscosity of the forkoil 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 forkoil separately.
