Wilbers fork Springs for Suzuki GSX-R 400 91-

Product Details

Wilbers fork spring kit, progressive, for Suzuki GSX-R 400, type GK 76 A, model year 91- (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 on the one hand and to increase the bottoming resistance on the other. Crucial is the combination of the "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 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 and, through constant rubbing, lead to a smoothing of the workpiece 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 air chamber height 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.
