Easy to install. Fit perfectly. Looks nice on my bike. Good quality. Took the factory shocks off. My bike rides much better with these shocks on.
Easy to install. Fitperfectly . They look nice nice on bike. Good quality.
excellent upgrade from a worn out softie on the rear of my 1988 Honda NX250
Great communication. Had a custom one done by them for my drag bike and it's perfect. I've had it a year now and what a different. Best deal for a perfect shock. Definitely recommend!
This set up has been everything I was expecting for the WR250r. The 461 shock with reserve mounted easily per instructions as did installing the progressive fork springs and oil. Your calculations on spring weights and oil viscosity for the riding I described has been great. Added 3/16-1/4 inch of preload on rear and now I just need to recalibrate myself. Rear tire puts power to the ground so much better. Keep up the great work! Andy
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
