Product details

Wilbers fork spring kit, progressive, for KTM 390 Duke, type KTM IS DUKE, model year 13- (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 recommend, we generally recommend a progressive fork spring to optimise responsiveness and, on the other hand, to 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 respective 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 component to be processed, such as Wilbers fork springs, are located together with a grinding medium specially adapted for this purpose in a vibrating container, the so-called trough vibrator.
The vibrations of the container generate a relative movement between the workpiece and the grinding medium and lead to a smoothing of the component surface due to constant rubbing against each other. 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 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.
