Let customers speak for us
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
My customers are very happy with their Nivomat purchases. One guy picked up his friend's bike for him and called me to order for him after riding his buddy's bike.
Happy withe your service.
Guys were easy to work with to get me the right option. Actually talked me down to a less expensive suspension because I ride on roads not race tracks.
