Product looks great. I have yet to install, but I can’t wait. I’m sure it’s gonna be wonderful.
Very helpful, Bryan in sales guided me to the exact product I needed for my bike.
I bought these for my 2017 GS Rallye and they totally transformed the bike! It now responds better in the front to sharp edged hits and in the Enduro Pro mode is very plush on the highway. The guys at EPM are very knowledgable and are riders themselves! I will be taking all my suspension work to them in the future. Give them a call you will be happy you did!

The fork springs were great. The springs sat higher then factory and alot less bottoming out now. Would highly recommend them to anyone.
All we can say is WOW...WOW...WOW!! Installed them myself even though I'm an old fat man. Watched the "Brad The Wizard" installation and it went fine. I set the initial sag the way the EPM Performance tech adjusted Cycle Fanatic's bike. Just gotta love YouTube. Anyway, my wife and I have done 700 - 800 miles since installation and to say night and day difference is just an understatement. Great, great product!!
Haven't had much riding time since we put them on, but for the short time we have been on the bike, you can notice a nice, smooth ride.
I started off with the +20 mm kit for my 2025 Honda Africa, twin adventure sport ES model. The springs in my opinion are too stiff and make the Suspension top out all the time but this particular kit that is the standard height stiffer Springs works really good. I do recommend using. 15 weight oil and the forks and in the shock if not even a 20 weight in the shock.

Bought this suspension setup so I didn’t have to adjust the preload when riding 2 up anymore. I will say, it’s a little stiffer than stock when riding solo, but when riding 2 up you can’t hardly feel the bumps anymore. Stock setup used to bottom out the shocks all the time, even properly adjusted. Since having the Wilbers installed,we haven’t bottomed out once. Thoroughly impressed and completely happy with my purchase.
Bike now feels more planted to the road, especially over rough surfaces.
