Wilbers fork springs for BMW K 100 LT/RT 83-99

Product Details

Wilbers fork spring set, progressive, for BMW K 100 LT/ RT, type BMW 100, model year 83-99 (fork oil please order separately), with ABE according to the application list

General Description

Depending on the application, Wilbers offers progressive or linear fork springs, made from the best and highest quality chrome-silicon steel. For touring and touring-sport applications, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. The combination of the 'Zero Friction' fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the respective vehicle is very important. If desired, 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 slide grinding:
During slide grinding, the workpieces to be processed, such as Wilbers fork springs, are placed together with an abrasive media specially tailored for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container generate relative movement between the workpiece and the abrasive media, leading to a smoothing of the workpiece surface through constant rubbing. At the end of the process, a fine, shiny 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 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.

Note: please order the fork oil separately.
