Shock Absorber Type 640 TS Road
The basic edition of the Wilbers Adjustline mono shock absorber features the same advanced technology as the more complex versions. The only difference is the omission of the compression reservoir, and therefore the ability to adjust high- and low-speed compression.
Despite this, the shock absorber makes no compromises in terms of response behavior or durability. Its radial piston design, wet-run operation, and Teflon-guided self-aligning bearings redefine the quality standard for a mono shock.
As usual, the spring preload is continuously adjustable, and rebound damping can be set via an open-bleed system in 22 clicks. The shock absorber can also be retrofitted with a variety of Wilbers accessories.

Let customers speak for us
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.
