Wilbers fork springs for Honda CB 650 B 81-

Product details

Wilbers fork spring kit, progressive, for Honda CB 650 B, Type RC 03, model year 81- (fork oil please order 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 bottoming resistance. Crucially, the 'Zero Friction' fork springs must be combined with the specially developed Wilbers fork oil and the correct air chamber for the respective vehicle must be observed. 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 (mass finishing):
During slide grinding (mass finishing), the component to be processed, such as Wilbers fork springs, are placed together with an abrasive body 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 body, and through constant rubbing, lead to a smoothing of the component 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.

Please note: please order the fork oil separately.
