Wilbers fork springs for Yamaha XT 600 Z 84-85

Product Details

Wilbers fork spring kit, progressive, for Yamaha XT 600 Z, Type 34 L / 55 W, model year 84-85 (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 the response and, on the other hand, to increase bottoming resistance. Crucially, 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, is important. If desired, an individual setup 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 parts 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 part surface. At the end of the processing, a fine, shiny 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 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.
