Shock Absorber Type 631 Competition
With compression tank on a flexible steel hose.
The Wilbers Adjustline shock absorber Type 631 is ideal for motorcycles with limited space. The compression reservoir connects to the shock absorber via a flexible steel hose — hose length and mounting angles can be chosen individually so the reservoir always finds its optimal position, for example on the rear frame where airflow provides additional cooling.
The compression tank houses the screws for adjusting high- and low-speed compression damping in 22 clicks. At maximum compression speed, a pressure control valve prevents the shock absorber from hydraulic locking.
Adjustment options for rebound, compression, and spring preload give you maximum control over your suspension.

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.
