Product details

Wilbers progressive forkspring set for BMW
F850GS, type 4G85, from model year 2018- (forkoil must be ordered separately)

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 touring-sport use, we generally recommend a progressive forkspring to optimise responsiveness and, on the other hand, increase bottoming reserves. The combination of "Zero Friction" forksprings with the specially developed Wilbers forkoil is very important, as is observing 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 light 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 components to be processed, such as Wilbers forksprings, are placed together with an abrasive media 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 media and, through constant rubbing, lead to a smoothing of the component surface. 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.
