Wilbers fork springs for Kawasaki GPZ 550 Uni Trak 84-89

Product Details

Wilbers fork spring kit, progressive, for Kawasaki GPZ 550 Uni Trak, type ZX 550 A, model year 84-89 (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, made from the best and highest quality chrome-silicon steel. For touring and sport touring, we generally recommend a progressive fork spring to optimise the response and, on the other hand, increase the bottoming resistance. Crucially, combine the "Zero Friction" fork springs with the specially developed Wilbers fork oil and ensure 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 slide grinding:
During slide grinding, the component to be processed, such as Wilbers fork springs, are located together with an abrasive body 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 body and, through constant rubbing, lead to a smoothing of the componentupper surface. At the end of the process, a fine, glossy 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 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.
