Product details

Wilbers forksprings set, progressive, for BMW F 900 XR, Type 4R90, from model year 2020- (forkoil to 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 applications, we recommend a progressive forkspring to optimise responsiveness and, on the other hand, to increase bottoming-out reserves. Crucially, the "Zero Friction" forksprings must be combined with the specially developed Wilbers forkoil, and the correct air chamber for the demcorresponding vehicle must be observed. If desired, individual tuning can be achieved in special cases by changing the air chamber. For motorsport applications, we recommend Wilbers' very lightweight linear chrome-silicon forksprings, which were co-developed by the motorsport team. "ZERO friction" friction reduction through vibratory finishing: During vibratory finishing, the component to be processed, such as Wilbers forksprings, are placed together with abrasive media specifically designed for this purpose in a vibrating container, known as a trough vibratory finisher. 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 componentupper surface. The result of this process is a fine, polished surface. 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.
