R 1300 GS | KA1

Optimized Wilbers WESA suspension for maximum comfort and perfect handling
A lot has changed on the suspension side compared to the previous model: the familiar ESA system has been replaced by the modern DSA system (Dynamic Suspension Adjustment). This not only enables dynamic damping adjustment, but also automatically adjusts the spring rate to the current load.
The system works with two different spring rates, which are intelligently activated depending on the payload. Adaptive vehicle height control can also be ordered as an option: When driving slowly, the vehicle automatically lowers by 30 mm, resulting in a seat height of a still impressive 852 mm when stationary.
It was already noticeable during the first test drives: The factory damper set-up no longer has much in common with the familiar comfort of the predecessor GS. Bumps and potholes are noticeably passed on to the rider - comfort has clearly fallen by the wayside.
There were two clear objectives:

• To bring noticeably more comfort to the chassis
• Realize an additional lowering by 30 mm

Our test bench measurements showed that high friction values and excessively tight compression damping in the low-speed range were responsible for the uncomfortable ride.
Our solution: We installed our specially developed piston with a friction-reducing piston band and a sensitive damping setup tuned for comfort.
Together with an optimized spring rate, the result is once again what a GS is all about: the typically comfortable GS ride.
The additional lowering by 30 mm also works without any problems, whether with or without the optionally adaptive vehicle height control - and all this without compromising on ride comfort. The standard adjustment range of the ZF OCV valve also offers maximum flexibility.
