Wilbers fork springs for Yamaha XV 1100 Virago US 85-

Product details

Wilbers fork spring kit, progressive, for Yamaha XV 1100 Virago US, Type 3 LP, model year 85- (fork oil to be ordered separately), with ABE according to 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 the initial response and, on the other hand, to increase resistance to bottoming out. 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 vehicle, is crucial. If desired, an individual setup can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very lightweight 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 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 componentupper surface due to constant rubbing. The result of the process is a fine, glossy surface.
For Wilbers fork springs, this reduction in surface roughness means minimisation of friction = ZERO friction.

Each fork spring kit 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.
