Let customers speak for us
I purposely waited to complete a review on my Wilbers Nivomat system so I could have more time to ride and critique it. I've still only ridden about 1,000 miles on it so far, but it is far superior to the stock suspension. I have not ridden a bike with the Legends suspension which is supposed to be the Nivomats competition, so I can't make that comparison. The Nivomat is a perfect blend of sport and touring. It gives you confidence cornering with positive feedback and no mush. I routinely bottomed out the stock suspension, but not the Nivomat. It holds firm and has improved my ride quality. It has been a wise purchase and well worth the money. Although I must say I'm glad I made my purchase before the tariffs.
Had the front & rear stock suspension replaced by EPM Performance on my 2021 HD RG Ltd in June2025 @~30,600 miles.
Immediately felt huge difference going over bumps on short-local rides.
.
Knew the true test was to wait and write a more realistic review AFTER my 9k mile 23 day trip coast to coast from PA to CA; which was some highway and lots of mountains and backroads and conditions and twisties.
Yes love these and would recommend set purchase for any touring bike.
PRO's: Smoother ride; excellent handlings & cornering; bike feels like it grabs/sticks to the road surface.
CON: This is just my assessment based on the ride/feel; front end is "stiff".
Mike and his team were easy to work with; I will be a repeat customer; to the tune of I recently purchased a slightly used 24 rg ltd that already had Legends front & rear and considering changing to Wilbers set as on the first bike.
Called EPM for verification that my information I provided them was correct. They answered my questions and shipped promptly.
The preset sag was spot on and installation was easy. Installed new fork kit. Ride is great. The more I ride it the more I realize how good the Wilbers Nivomat system is.
Simple to put on. My bike finally has some give when I sit on it. Ohio roads are terrible, much nicer ride.
Great shop! Cleanest & most organized I've ever seen...did a great jb!!
Best shocks I have ever had both on the front and rear I would do it again!!
This is my second purchase from EPM and both times have been pleasant and shipping has been fast.
