Wilbers fork springs for Yamaha TZR 250 R/ SP 91-

Product Details

Wilbers fork spring kit, progressive, for Yamaha TZR 250 R/ SP, Type 3 XV, model year 91- (fork oil please order 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 on the one hand and to increase bottoming resistance on the other. Crucial is 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. 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 with the motorsport team.

"ZERO friction" friction reduction through tumble finishing:
During tumble finishing, the parts to be processed, such as Wilbers fork springs, are placed together with abrasive media 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 media, leading to a smoothing of the part surface through constant rubbing. At the end of the process, a fine, polished surface is achieved.
For Wilbers fork springs, this reduction in surface 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 air chamber height 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.
