Wilbers forkfedern for BMW K 75 S 86-90

Product Details

Wilbers forkfedern set, progressive, for BMW K 75 S, Type BMW 75, model year 86-90 (forköl must be ordered separately), with ABE according to the usage list.

General Description

Depending on the application, Wilbers offers progressive or linear forkfedern, made from the best and highest quality chrome-silicon steel. For touring and touring-sport, we generally recommend a progressive forkfedern to optimise response and, on the other hand, increase bottoming-out reserves. The combination of "Zero Friction" forkfedern with the specially developed Wilbers forköl and adhering to the correct air chamber for the correspondinge vehicle is very important. If desired, an individual setup can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very light linear chrome-silicon forkfedern from Wilbers, which were co-developed by the Motorsport Team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the componente to be processed, such as Wilbers forkfedern, are located together with an abrasive body 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 body, and through constant rubbing, lead to a smoothing of the componentupperfläche. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfedern, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each forkfedern set includes a recommendation for the viscosity of the forköl 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 forköl separately.
