Wilbers fork springs for Kawasaki VN 1500 87-

Product Details

Wilbers fork spring kit, progressive, for Kawasaki VN 1500, type VNT 50 A, model year 87- (fork oil must be ordered separately), with ABE according to the application list.

General Description

Depending on the application, Wilbers offers 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 responsiveness 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 corresponding vehicle must be observed. If desired, an individual setup can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend Wilbers' very lightweight linear chrome-silicon fork springs, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the components to be processed, such as Wilbers fork springs, are placed 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, leading to a smoothing of the componentupper surface through constant rubbing. 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 regarding 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.
