Product details

Wilbers forkfedern set, progressive, for Yamaha XTZ 660 Tenere, Type 4 MD / 3 YF, model year 91- (forköl please order separately), with ABE according to application list

General description

Depending on the application, Wilbers offers progressive or linear forkfedern, made from the best and highest quality chrome-silicon steel. For touring and touring-sport applications, we generally recommend a progressive forkfeder to optimise responsiveness and, on the other hand, increase bottoming resistance. The combination of the 'Zero Friction' forkfedern with the specially developed Wilbers forköl, as well as observing 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 Wilbers' very lightweight linear chrome-silicon-forkfedern, which were co-developed by the Motorsport Team.

"ZERO friction" friction reduction through slide grinding:
During slide grinding, the workpieces to be processed, such as Wilbers forkfedern, are placed together with a grinding medium 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 grinding medium and, through constant rubbing against each other, lead to a smoothing of the workpiece surface. At the end of the process, a fine, shiny surface is achieved.
For Wilbers forkfedern, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of forkfedern comes with a recommendation for the viscosity of the forköl and the height of the air chamber in the fork. These values have been determined by experienced Wilbers technicians and ensure optimum riding comfort and feedback at the front wheel.

Note: please order the forköl separately.
