Product details

Wilbers fork spring kit, progressive, for BMW G 310 GS, Type 5G31, model year 17-, 40 mm lowering including reducing sleeves, (fork oil must be ordered separately), with ABE according to 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 applications, we generally recommend a progressive fork spring to optimise response and increase bottoming resistance. Crucially, combine the "Zero Friction" fork springs with the specially developed Wilbers fork oil and observe the correct air chamber for the respective vehicle. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport use, we recommend the very lightweight linear chrome silicon fork springs from Wilbers, which were co-developed with 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, known as a trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the abrasive media, leading to a smoothing of the workpiece surface through constant rubbing. At the end of processing, a fine, glossy surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means minimised friction = ZERO friction.

Each fork spring set includes a recommendation for the viscosity of the fork oil 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 handlebar.

Please note: please order the fork oil separately.
