Shock Absorber Type 644 WESA Dynamic Feedback Rear
The BMW F 750/850 GS and F 900 R/XR now feature semi-active “Dynamic ESA” suspension. With our WESA Dynamic Feedback upgrade, you can lower the motorcycle by up to 60 mm while keeping full ESA handlebar control. An additional manual feedback adjuster lets you fine-tune comfort and response, and each shock is customized to rider weight and load.
The original electronic components are reused, so your OEM suspension must be sent in for conversion (or processed by a trained dealer). We provide a 5-year warranty and an ABE approval.
*If lowered, a TÜV inspection is required due to the shortened side stand.
NOTE
To get a linkage to the Dynamic ESA-System you have to send in your original shock absorber. The costs are 149 €.

Let customers speak for us
Can’t rave enough about the set-up! Two weeks after installation, I went on a 9 day ride from Staten Island NY to Key West FL and back, with various stops in between. The bike handled so smoothly, it was the best long ride i ever had. Never bottomed out either! I’ve been recommending the Wilber’s Nivomat suspension & EPM Performance to everyone I meet. Thank you.
What a great product. So much better than stock. Easy set up and go. No more 3 different adjustments.
Front cartridges for my 2021 Harley heritage softail classic. Solid and stable w no bouncing and jittering. Huge difference from stock.
I have about 50 miles riding on this shock so far. It works and feels great.
I had hyperpro one inch lowered shock and springs installed at epm, on my 2025 z650, great service, (thank you guys). Before the install i could feel every bump in the road, after the ride was very smooth except for very large holes. total different bike. Very satisfied.
The shock seems to do it's job - it absorbs road bumps and rebounds quickly to take on the next one.
