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.
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.
