Product details

Wilbers fork fork spring set, progressive, for Yamaha FJ 1200, type 3 YA / 4 YA / 3 CY, model year 91-99 (fork oil please order separately), with ABE according to the application list

General description

Depending on the application, Wilbers offers you progressive or linear fork fork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and touring sport applications, we generally recommend a progressive fork fork spring to optimise the response characteristics and, on the other hand, to increase the bottoming resistance. The combination of "Zero Friction" fork fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the respective vehicle, is very 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 fork springs from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers fork fork springs, are located together with an abrasive media specially adapted for this purpose in a vibrating container, the so-called 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, a fine, glossy surface is achieved.
For Wilbers fork fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of fork 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 optimum riding comfort and feedback at the front wheel.

Note: please order the fork oil separately.
