Wilbers fork springs for Yamaha XVS 1100 DRAG STAR 98-

Product details

Wilbers fork spring kit, progressive, for Yamaha XVS 1100 DRAG STAR, type VP 05, model year 98- (fork oil to be ordered separately), with ABE according to the usage 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 sport touring, we generally recommend a progressive fork spring to optimise responsiveness and increase bottoming resistance. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil and observing the correct air chamber for the corresponding vehicle 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 specifically tailored 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 through constant rubbing. At the end of the process, 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 air chamber height in the fork. These values have been determined by experienced Wilbers technicians and ensure optimum riding comfort and feedback at the front wheel.

Note: please order the fork oil separately.
