Wilbers fork spring kit, progressive, for Honda CB650R, 2024- , 30 mm lowering

Product details

For 30 mm lowering, incl. reducing sleeve.

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, increase bottoming-out reserves. The combination of the "Zero Friction" fork springs with the specially developed Wilbers fork oil and adherence to the correct air chamber for the respective vehicle is very important. If desired, individual adjustment 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 components to be processed, such as Wilbers fork springs, are placed together with an abrasive medium specially 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 medium, and through constant rubbing, lead to a smoothing of the componentupper surface. 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 set of fork springs 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 front wheel.

Note: please order the fork oil separately.
