Product Details

Wilbers fork spring kit, progressive, for HONDA NC750XA / XD, Type RC90, model year 16-, 20 mm lowering, incl. reducing sleeves, (fork oil to be ordered separately), 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 applications, we generally recommend a progressive fork spring to optimise response and, on the other hand, increase bottoming-out reserves. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil and observing the correct air gap for the respective corresponding vehicle is very important. If desired, individual tuning can be achieved in special cases by changing the air gap.
For motorsport applications, we recommend the very lightweight linear chrome-silicon fork springs from Wilbers, which were co-developed with the motorsport team.

"ZERO friction" reduction of friction through slide grinding:
During slide grinding, the components to be processed, such as Wilbers fork springs, are placed together with an abrasive media specially tailored for this purpose in a vibrating container, known as a vibratory finisher.
The vibrations of the container create a relative movement between the workpiece and the abrasive media, leading to a smoothing of the component upper surface through constant rubbing. 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 fork spring set includes a recommendation for the viscosity of the fork oil and the height of the air gap 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.
