140mm CSC Linear Steering Damper

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.

Great Ride. Right length. Great looking Shock

What a great product. So much better than stock. Easy set up and go. No more 3 different adjustments.

All issues fixed. The ride is great again!

Tremendous difference. Could not ask for more.

Transformational upgrade to the Z650rs. Truly.

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.

Worked great made a big difference in my confidence

The shock seems to do it's job - it absorbs road bumps and rebounds quickly to take on the next one.
