Shock Absorber Type 640 Road
The Wilbers suspension solution delivers a significantly improved fork response by replacing the original linear springs with progressive ones. The second spring rate provides greater reserve and stability during demanding riding conditions.
On the rear axle, the spring rate has been adjusted using a slightly stiffer spring combined with optimized rebound and compression damping. This setup offers a wider adjustment range compared to the original shock absorber and ensures improved handling, comfort, and feedback.
The suspension geometry on both the front and rear axles has also been refined through precise tuning of the negative spring travel, resulting in a more balanced and controlled ride.
The basic edition of the Wilbers Adjustline mono shock absorber features the same advanced technology as the more complex models. The only difference is the omission of the compression reservoir and, therefore, the ability to adjust high- and low-speed compression. Despite this, it makes no compromises in response behavior or durability. The radial piston, wet-run design, and Teflon-guided self-aligning bearings redefine the standard of quality for a mono shock. As usual, the spring preload can be continuously adjusted, and the rebound damping can be fine-tuned via an open-bleed system in 22 clicks. The shock absorber can also be retrofitted with numerous 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.
