Wilbers fork springs for Aprilia RS 250 98-

Product details

Wilbers fork spring kit, progressive, for Aprilia RS 250, type LD A1, model year 98- (please order fork oil separately), with ABE according to the usage list.

General description

Depending on the application, Wilbers offers you 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, on the other hand, to increase bottoming-out reserves. 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, an individual setup 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 components to be processed, such as Wilbers fork springs, are located together with a grinding media specifically matched for this application in a vibrating container, the so-called trough vibrator.
The vibrations of the container create a relative movement between the workpiece and the grinding media, and through constant rubbing, lead to a smoothing of the componentupper surface. 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 set of fork springs includes a recommendation regarding 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 optimum riding comfort and feedback at the front wheel.

Note: please order the fork oil separately.
