Shock Absorber Type 643 Competition QS
Swiveling, diagonally mounted compression reservoir.
The reservoir is mounted at an angle and can swivel, offering numerous installation options on space-constrained bikes. A solid milled upper mount integrates the high- and low-speed compression adjusters. Both compression and rebound provide 22 clicks of adjustment for uncompromised fine-tuning. A pressure-control valve prevents hydraulic blocking and tames sudden impacts. Spring preload is infinitely adjustable via the supplied hook spanner or optionally hydraulically. The reservoir angle can be re-indexed later by any trained Wilbers partner.

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.
