Wilbers fork springs for Triumph Thunderbird 1600 09-

Product details

Wilbers fork spring set, progressive, for Triumph Thunderbird 1600, type B 16 BA, model year 09- (fork oil to be ordered separately), with ABE according to the 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 use, we typically recommend a progressive fork spring to optimise responsiveness and, on the other hand, to increase bottoming resistance. Crucially, combine the "Zero Friction" fork springs with the specially developed Wilbers fork oil, and observe the correct air chamber for the respective vehicle. If desired, in special cases, an individual setup can be achieved by changing the air chamber.
For motorsport applications, we recommend the very light linear chrome-silicon fork 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 fork springs, are placed together with an abrasive media specifically adapted 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 workpiece upper surface through constant rubbing. At the end of the process, a fine, gleaming surface is achieved.
For Wilbers fork springs, this reduction in surface roughness means minimised friction = ZERO friction.

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