Wilbers fork springs for Yamaha TRX 850 96-99

Product details

Wilbers fork spring set, progressive, for Yamaha TRX 850, type 4 UN, model year 96-99 (please order fork oil 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-out reserves. Crucially, combine "Zero Friction" fork springs with the specially developed Wilbers fork oil and observe the correct air chamber for the corresponding vehicle. If desired, individual tuning 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 with the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the component to be processed, such as Wilbers fork springs, are placed together with an abrasive media specifically tailored 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 through constant rubbing. The result of the process is a fine, shiny surface.
For Wilbers fork springs, this reduction in surface roughness means minimising 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 at the front wheel.

Note: please order the fork oil separately.
