Product Details

Wilbers fork spring kit, linear, for BMW HP4, Type K 10, model year 12-14, spring rate: 10.5 (please order fork oil separately), with ABE according to the application list

General Description

Depending on the application, Wilbers offers you progressive or linear fork springs, manufactured from the best and highest quality chrome silicon steel. For touring and touring sport, we generally recommend a progressive fork spring to optimise the response and, on the other hand, to increase the bottoming resistance. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil is very important, as is observing the correct air chamber for the respective vehicle. If desired, in special cases, individual tuning can be achieved by changing the air chamber.
For motorsport applications, we recommend the very light linear chrome silicon fork springs from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers fork springs, are located together with an abrasive media specially adapted for this purpose in a vibrating container, the so-called trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive media and, through constant rubbing against each other, lead to a smoothing of the workpiece surface. At the end of the processing, a fine, glossy surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring set includes a recommendation for the viscosity of the fork oil and the air chamber height 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 fork oil separately.
