Wilbers forkfedern for Ducati Monster 900 S 4 01-

Product Details

Wilbers forkfedern set, progressive, for Ducati Monster 900 S 4, type M 4, model year 01- (forkoil must be ordered separately), with ABE according to the application list.

General Description

Depending on the application, Wilbers offers progressive or linear forkfedern, manufactured from the best and highest quality chrome-silicon steel. For touring and touring-sport applications, we typically recommend a progressive forkfedern to optimise the response and, on the other hand, to increase the bottoming resistance. The combination of "Zero Friction" forkfedern with the specially developed Wilbers forkoil, as well as observing the correct air chamber for the correspondinge vehicle, is very important. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend Wilbers' very light linear chrome-silicon forkfedern, 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 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 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 set of forkfedern 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 to the front wheel.

Note: please order the forkoil separately.
