Product details

Wilbers forkfork spring set, progressive, for Beta Alp 4.0, Type T 2, model year 12-13 (forkoil please order separately), with ABE according to 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 use, we generally recommend a progressive forkfork spring to optimise responsiveness and increase bottoming resistance. The combination of "Zero Friction" forkfork springs with the specially developed Wilbers forkfork oil and adherence to the correct air chamber for the respective vehicle is very important. If desired, individual tuning can be achieved in special cases by changing the air chamber.
For motorsport applications, we recommend the very light 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 components to be processed, such as Wilbers forkfork springs, are placed together with an abrasive media specially 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, leading to a smoothing of the component surface through constant rubbing. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of forkfork springs includes a recommendation for the viscosity viscosity of the forkfork oil and the height of the air chamber 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 forkfork oil separately.
