Let customers speak for us
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!!
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.
The rear shock arrived earlier than expected. EPM customer service was 10/10, part arrived with no issues and all the process was very smooth.
Thank you for providing good customer service.
Finally had a chance to do an extended ride this weekend I'm super pleased on how much smoother the bike rode 2-up.
My wife really enjoyed the ride much.
I would not hesitate on buying this for a future bike. Thanks for the awesome ride.
Wanted to upgrade the OEM suspension on my 2023 KTM Super Adventure S. Wanted springs to match my weight and riding style. Hyperpro fork spring kit arrived quickly and installed by local suspension shop. EPM has been my preferred vendor for both my KTM and Husqvarna 901 suspension needs.
The YSS shocks are a huge improvement over the stock 2015 Triumph Scrambler 900 rear shocks. The quality is similar to the O shocks I am running on my 1999 Harley Road King. Thanks
