Product details

Wilbers forkspring kit, progressive, for Harley Davidson Pan America, Type RA1, from model year 2021-
(forkoil to be ordered separately)

General description

Depending on the application, Wilbers offers progressive or linear forksprings, manufactured from the best and highest quality chrome-silicon steel. For touring and touring sport, we generally recommend a progressive forkspring to optimise response and, on the other hand, to increase bottoming resistance. Crucially, combine the "Zero Friction" forksprings with the specially developed Wilbers forkoil and observe the correct air chamber for the respective vehicle. 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 forksprings 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 forksprings, are located together with an abrasive media specifically 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, and through constant rubbing against each other, lead to a smoothing of the workpiece surface. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forksprings, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each forkspring set includes a recommendation for the viscosity of the forkoil 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 forkoil separately.
