Wilbers fork springs for Yamaha FZ 8 S / SA 13-

Product details

Wilbers fork spring set, progressive, for Yamaha FZ 8 S / SA, Type RN 25, model year 13- (fork oil please order separately), with ABE according to 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 characteristics and, on the other hand, to increase the bottoming resistance. Crucial is the combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing 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 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 placed together with an abrasive media specifically adapted for this purpose in a vibrating container, known as a trough vibrator.
The vibrations of the container generate a relative movement between the workpiece and the abrasive media and, through constant rubbing, lead to a smoothing of the workpiece surface. At the end of the process, a fine, polished 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 to the rider.

Note: please order the fork oil separately.
