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.
The ZF-PA 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.
E-PA 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.
The "Wilbers LDC" shock absorber offers excellent comfort in all circumstances. It adapts
to different loading situations without any effort on the riders part, automaticalle without
any buttons or electronics!
After the passenger with or without luggage takes a seat, the deeply compressed suspension pumps
itself up after a few meters of riding, back to the defined riding level as the shock absorber
delivers additional oil into its cylinder by its own stroke movement. The resulting pressure
increase leads to the adjustment in damping.
