Shock Absorber Type 641 Competition
This shock absorber connects its compression tank to the main body using a flexible steel hose, making it an ideal choice for motorcycles with limited installation space. The hose can be routed freely wherever space allows — for instance, along the rear frame — where airflow can also aid in additional cooling. The external adjustment screws for high- and low-speed compression, each adjustable in 22 clicks, are easily accessible. Rebound damping can be fine-tuned through an open-bleed system with 22 clicks, and the spring preload is continuously adjustable.
Product may vary from picture.
For a lowering of 50mm the special fork-spring kit is required.
Spring preload, compression and rebound damping adjustable. ride height adjustment not possible

I tried two after market rear shocks on my‘23 Road Glide and wasn’t pleased at all with either set. My wife gave me an evil eye when I-told her I had ordered another set (3rd set) of shocks. About an hour into our first ride on the Wilbers she acknowledged the Wilbers were a huge improvement.
The shocks are very easy to install and make the ride as smooth as can be.
Fantastic upgrade that really improves the ride.
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.
