Let customers speak for us
The process of working with EPM Performance was as smooth as the Wilber’s suspension system. Quality company that delivered as advertised.
Suspension system is awesome, makes a huge difference on my 2014 CVO Ultra-limited. EPM Performance delivered a system that was pretty much dialed in and ready to ride right out of the box. Instructions to install are solid and easy to follow.
Spring works beautifully! Really changed the dynamic of my bike. The original suspension was very springy and soft. The new one makes the bike handle much better.
Great product! Thank you
Easy to order. Customer service responsive. Well packaged and quick to ship
The bikes handles better, I can now flatfoot with both legs down (I have a 30" inseam) and the lateral stand doesn't need to be shortened. Recommended modification!
Went to EPM with a major wobble and bouncing on my 2025Road Glide.
Mike installed new springs and heavier oil. Took an overnight trip to Maine the following. We road fast and hard. I have zero wobble and no bouncing since the install. If you have any suspension issues or questions, GO SEE THESE GUYS!!!! You will not bedisappointed.
Epm is a great company to work with a very knowledgeable and very friendly they answered all of my questions and completed the job in a timely fashion!
Epm crew is very knowledgeable, super friendly, and have a true passion for the sport! They are the only suspension company I’ll use
Thanks to Bryam for helping me figure out the right set of springs for my weight for the shock upgrade. Bought the YSS RG RG362 twin reservoir shocks and Fork Upgrade Kit for my 2018 Triumph Bonneville T100. Really transformed the ride! Great value for the money. EPM transaction was smooth for an international customer arriving on time. EPM gets suspension tuning!
Upgraded 2018 Bonneville T100 with this kit. Much stiffer and better damping than stock for sure. No front-end dive under braking and no pogo-sticking over road bumps. Excellent value for the money!
Fantastic! Really transforms my 2018 Bonneville T100. Bryan at EPM was able to spec the correct spring rate for my weight. No bottoming out! No more underdamped suspension! Excellent value for the money!
Product looks great. I have yet to install, but I can’t wait. I’m sure it’s gonna be wonderful.
