Product details

Wilbers fork fork spring set, progressive, for Yamaha SRX 400, Type 1 XM / 1 XL, model year 85-89 (fork oil please order separately), with ABE according to usage list

General description

Depending on the application, Wilbers offers 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 responsiveness and, on the other hand, increase bottoming resistance. The combination of the "Zero Friction" fork fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the corresponding vehicle is very important. If desired, individual tuning 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 component workpieces, such as Wilbers fork fork springs, are placed together with a grinding 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 grinding body, and through constant rubbing, lead to a smoothing of the componentupper surface. At the end of the process, a fine, shiny 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 for 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 optimum riding comfort and feedback at the front wheel.

Note: please order the fork oil separately.
