Wilbers Suspension type 640 Road rear for BMW F900GS

BMW F900GS Bikes

BMW F800GS (2024- ), F900GS & F900GS Adv Wilbers Suspension type 640 Road rear

The BMW F900 GS with sport suspension (Enduro package) comes from the factory with overly stiff springs and an imprecise fork breakaway. Wilbers improves this with softer springs featuring tuned rebound and compression damping, a progressive fork spring, upgraded fork oil, and an optimized air chamber. Additionally, the negative travel is increased, resulting in a significantly more stable, safer, and comfortable ride—especially during braking and cornering.

Wilbers Shock Absorber Type 640 Road: Adjustable spring preload and rebound damping
For BMW F900GS with Sport suspension
The basic version of the Wilbers Adjust-Line mono shock impresses with high-quality engineering without unnecessary frills: a radial piston, wet-running guide, and Teflon-coated spherical bearings ensure reliable responsiveness and long service life. The spring preload can be continuously adjusted, while the rebound damping can be finely tuned in 22 steps via an open bleed system - ideal for a perfectly personalized riding experience. Even without an external reservoir, the shock offers significantly better performance than many stock solutions and can be flexibly adapted to weight, load, and riding style thanks to numerous upgrade options. While the standard spring preload adjustment is carried out using the included hook spanner, the optional hydraulic version allows for a significantly easier and more convenient adjustment via a handwheel. When your vehicle is carrying a heavier load, the correct ride height can thus be restored in no time without having to use a hook spanner.
