Wilbers Fork Spring - Zero friction - progressive
solution maybe is the most comfortable way to adjust the spring preload. Using a hand knob that comes with a bracket specified for your motorcycle, you can easily adjust the riding level to match additional passenger and/or loading situations. The adjustment range is 10 mm.
The X-PA offers you the option to regulate the spring preload and therewith the vehicle level by the included box spanner in a breath. The purely mechanical adjustment mechanism is very light and, due to its robustness, best suited for enormous loads. The adjustment range is 15 mm.
is a hydraulic spring tensioner that is directly integrated on the shock absorber. The advantage is that you do not have to mount an external hand knob to the vehicle. Nowadays especially current motorcycle models rarely offer space for a separate had wheel. Easily reachable and adjustable without much force, this preload option can be tuned for up to 15 mm.
is an electrohydraulic spring preload. This system is exclusive to our WESA-X shock absorbers. Using the control unit of the WESA-X system, you can adjust the seating level at the push of a button to different loading situations in 5 steps.
the Wilbers ride-height-adjustment
the length of the shock absorber can be modified over a thread located at the lower shock mount for +/-5mm. Normally this is possible while the shock absorber is installed.
Depending on the type of the motorcycle, the seating height can be adjusted for up to +/-15mm. This is for example useful on the racetrack to influence the caster and therewith the steering behavior of the motorcycle.
Wilbers progressive fork springs
friction" Friction reduction through fine grinding, resulting in »ZERO friction«.
In vibratory finishing, the components to be machined, e.g. components, e.g. our fork springs, together with a specially together with a grinding wheel specially adapted for this in a vibrating container, the so-called trough vibrator.
Product may differ from the picture.
Recommended viscosity and air chamber:
The vibrations of the container generate a relative movement between the workpiece and the grinding wheel and, due to the constant rubbing against each other, lead to a smoothing of the component surface.
At the end of the processing there is a fine, shiny surface. Particularly with our fork springs, this reduction of the surface roughness means a minimization friction = ZERO friction.
Important is the combination with our specially developed Wilbers fork oil and the observance of the correct air chamber for the corresponding vehicle.
