Adjust the rear suspension to your weight, riding style, luggage, and use with a model-specific shock absorber
The shock absorber determines how smoothly the rear wheel follows uneven surfaces and how the motorcycle responds during acceleration, braking, and cornering. A worn or improperly fitting shock absorber can cause bouncing, bottoming out, instability, and reduced grip. With a model-specific replacement, you can restore or improve the performance of the suspension system.
This collection includes various TFX Suspension shock absorbers for street use, touring, adventure, and circuit riding. Depending on the type, the equipment ranges from straightforward replacement shocks to fully adjustable versions with separate or piggyback reservoirs.
For selected older models, YSS shock absorbers are also available. These are offered as direct replacements for worn original shock absorbers and may provide adjustable preload and rebound depending on the version.
The correct spring rate depends on the total weight of the rider, clothing, passenger, and luggage. A standard spring chosen for an average rider may be too soft or too stiff for your situation.
With a custom-assembled TFX shock absorber, rider weight, riding style, and typical use can be taken into account. This way, the basic setup better suits commuting, long trips, sporty street riding, or circuit riding.
Preload adjusts the starting position and the sag under load. It does not actually make the spring stiffer but determines how much the suspension compresses under weight.
Rebound controls how quickly the shock absorber returns after being compressed. More advanced models also offer compression adjustment, which changes the resistance during compression. Adjust these settings step-by-step and always note the original settings.
Most modern motorcycles use a single central monoshock. Classic, custom, and certain touring motorcycles use two rear shock absorbers. Selected BMW models also feature a separate shock absorber in the Telelever front suspension.
These product types are not technically interchangeable. Always choose based on the exact motorcycle model, version, year of manufacture, and mounting position.
Leaks, reduced damping, excessive bouncing, uneven tire wear, or a motorcycle that sags deeply under load can indicate wear or incorrect adjustment. Also check tires, bearings, and linkage parts first.
After installation, ride height and sag must be set. If in doubt, have the installation and basic adjustment performed by a suspension specialist, especially when the shock absorber is part of a linked BMW or electronic suspension system.
