Our
Wilbers-PA
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.
The
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.

With
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.
On the Honda NC 750 XA/XS (RH09), the seat height has been reduced from 830mm to 800mm compared to its predecessor.
Originally, the fork has progressive springs, whereby the first spring rate is too low and thus also changes early to the second spring rate, which is clearly too hard.
We use slightly harder springs here at first, but softer, progressive springs in the second spring rate. This conversion results in better fork response.
The rear shock is also fitted with a progressive spring from the factory, which has a poor block value and thus permanently stresses the second spring, which is again too hard.
Our solution relies on linear springs on the strut, in conjunction with optimized rebound and compression damping.
The suspension geometry on the front and rear axles was sensibly adjusted via the negative spring deflections in order to correct the negative spring weights, which were slightly too high as standard.
This results in a safer ride and better handling.
