Wilbers fork springs for Yamaha YZF 750 R 93-98

Product details

Wilbers fork spring set, progressive, for Yamaha YZF 750 R, Type 4 HN, model year 93-98 (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 applications, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. 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 very important. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend Wilbers' very lightweight linear chrome-silicon fork springs, which were co-developed by the Motorsport Team.

"ZERO friction" friction reduction through slide grinding:
During slide grinding, the parts to be processed, such as Wilbers fork springs, are placed together with an abrasive body specially designed 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 body, and through constant rubbing, lead to a smoothing of the part surface. At the end of the processing, a fine, glossy surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each fork spring set 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 handlebars.

Note: please order the fork oil separately.
