Wilbers fork springs for Yamaha XV 1000 TR 1 81-

Product details

Wilbers fork spring kit, progressive, for Yamaha XV 1000 TR 1, Type 5 A 8, model year 81- (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 finest and highest quality chrome-silicon steel. For touring and touring sport, we generally recommend a progressive fork spring to optimise the response and, on the other hand, to increase the bottoming resistance. Crucially, the combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil and observance of the correct air chamber for the corresponding vehicle is important. If desired, in special cases, individual tuning can be achieved 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 vibratory finishing:
During vibratory finishing, the components to be processed, such as Wilbers fork springs, are located together with an abrasive 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 abrasive body and, through constant rubbing against each other, lead to a smoothing of the componentupper surface. At the end of the processing, a fine, shiny 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 front wheel.

Note: please order the fork oil separately.
