Wilbers Fork Springs for Honda VFR 400 R 89-90

Product Details

Wilbers fork spring set, progressive, for Honda VFR 400 R, Type NC 30, model year 89-90 (fork oil please order separately), with ABE according to usage 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 typically recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil, as well as observing the correct air chamber for the corresponding respective 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 fork springs from Wilbers, which were co-developed by the motorsport team.

"ZERO friction" friction reduction through barrel finishing:
During barrel finishing, the component components to be processed, such as Wilbers fork 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 generate 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 viscosity of the fork oil 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 handlebars.

Note: please order the fork oil separately.
