Wilbers fork springs for Yamaha FZR 1000 86-88

Product details

Wilbers fork spring set, progressive, for Yamaha FZR 1000, Type 2 LA, model year 86-88 (please order fork oil 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 touring sport, we generally recommend a progressive fork spring to optimise the response behaviour and, on the other hand, to increase the bottoming resistance. Crucially, 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, is important. If desired, in special cases, individual tuning can be achieved 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 workpieces 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 and, through constant rubbing against each other, lead to a smoothing of the workpiece surface. At the end of the process, there is a fine, shiny surface.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring set includes a recommendation regarding 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 handlebar.

Note: please order the fork oil separately.
