Wilbers progressive fork spring set for Triumph Bonneville Bobber, Type DV 01, model year 16-

Product details

Wilbers progressive fork spring set for Triumph Bonneville Bobber, Type DV01, model year 16- (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 applications, we generally recommend a progressive fork spring to optimise responsiveness and increase bottoming resistance. The combination of "Zero Friction" fork springs with the specially developed Wilbers fork oil is very important, as is observing the correct air chamber for the respective vehicle. If desired, individual tuning 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 vibratory finishing:
During vibratory finishing, the workpieces to be processed, such as Wilbers fork springs, are placed together with an abrasive medium 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 medium, leading to a smoothing of the workpiece surface through constant rubbing against each other. At the end of the processing, a fine, glossy 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 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.
