Product details

Wilbers fork spring set, progressive, for BMW F650GS, Type R13, Model Year 00-07, For factory lowering and additional Wilbers 30 mm lowering, (fork oil to be ordered separately), with ABE according to the application list

General description

Depending on the application, Wilbers offers 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 responsiveness and, on the other hand, to increase bottoming resistance. Crucially important is the combination of the "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the vehicle in question. If desired, an individual tuning can be achieved in special cases 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 specifically designed 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 lead to a smoothing of the workpiece surface through constant rubbing against each other. At the end of the process, a fine, gleaming 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.
