Wilbers fork springs for Yamaha YZF 1000 Thunderace 96-00

Product Details

Wilbers fork spring set, progressive, for Yamaha YZF 1000 Thunderace, type 4 VD / 4 SV, model year 96-00 (fork oil must 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, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming-out reserves. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the respective corresponding, 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 springs from Wilbers, which were co-developed by 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 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 component upper through constant rubbing. At the end of the process, a fine, shiny upper is achieved.
For Wilbers fork springs, this reduction in upper 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.
