Wilbers forkfork springs for HD Dyna Superglide Sport FXDX

Product details

Wilbers forkfork spring kit, progressive, for Harley-Davidson Dyna Superglide Sport FXDX, type FD 1, model year 01-05 (forkoil please order separately), with ABE according to the application list

General description

Depending on the application, Wilbers offers progressive or linear forkfork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and touring-sport applications, we typically recommend a progressive forkfork spring to optimise response and, on the other hand, to increase bottoming resistance. Crucial is the combination of the "Zero Friction" forkfork springs with the specially developed Wilbers forkoil, as well as observing the correct air chamber for the correspondinge vehicle. If desired, in special cases, an individual setup can be achieved by changing the air chamber.
For motorsport applications, we recommend the very lightweight linear chrome-silicon forkfork springs 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 forkfork springs, are placed together with 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, lead to a smoothing of the componentuppersurface. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfork springs, this reduction of surface roughness means minimisation of friction = ZERO friction.

Each forkfork spring set includes a recommendation regarding the viscosity of the forkoil and the air chamber height in the forkfork. These values have been determined by experienced Wilbers technicians and ensure optimal riding comfort and feedback at the front wheelhandlebars.

Note: please order the forkoil separately.
