Wilbers fork springs for KTM 790 Duke 18-

Product details

Wilbers fork spring set, linear, for KTM 790 Duke, model year 18- (forköl please order separately), for lowering by 40 mm including reducing sleeven, 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, 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 forköl and observing the correct air chamber for the demcorrespondinge 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 lightweight linear chrome-silicon forkfedern from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers forkfedern, are located together with an abrasive media specially 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, and through constant rubbing against each other, lead to a smoothing of the componentupperfläche. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfedern, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of forkfedern includes a recommendation for the viscosity of the forköl 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 to the front wheel.

Note: please order the forköl separately.
