Wilbers fork springs for Yamaha RD 500 LC 84-

Product Details

Wilbers fork spring kit, progressive, for Yamaha RD 500 LC, type 47 X / 1 GE, model year 84- (fork oil to 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 recommend we generally use a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. Crucially important 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, in special cases, individual tuning can be achieved by changing the air chamber.
For motorsport applications recommend we use the very lightweight linear chrome-silicon fork springs from Wilbers, which were co-developed with the motorsport team.

"ZERO friction" friction reduction through slide grinding:
During slide grinding, the component 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, glossy 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 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.
