Let customers speak for us
I had hyperpro one inch lowered shock and springs installed at epm, on my 2025 z650, great service, (thank you guys). Before the install i could feel every bump in the road, after the ride was very smooth except for very large holes. total different bike. Very satisfied.
The shock seems to do it's job - it absorbs road bumps and rebounds quickly to take on the next one.
Resolved the issue with my 2010 BMW T1209GSA front leaking OEM shock. I was leaking. The turnaround was quick and worked perfectly. Thanks
Mike took care of the installation, he is very knowledgeable and friendly. He did a great install and in a short amount of time.
I recently bought a used 2014 Honda NC750X with 6000 miles from a Honda dealer. The front end was harsh, skittish and like a pogo stick, the bike did not track well braking was jumpy. The front tire showed irregular wear, which is not uncommon. The rear tire was brand new with only a few hundred miles on it and it was starting to show uneven wear. Overall, the bike handle lousy and literally felt unsafe during cornering, braking and general riding. I bought and installed the Hyperpro spring set installing the Fork Springs first. I flushed and cycled the forks with other fresh fork oil several times to get out the old gunk. Using the included hyperpro 15 weight fork oil the bike was transformed into a normal acting predictable, enjoyable Motorcycle. Next, I replaced the rear shock spring and it feels like a new motorcycle overall being predictable and responsive and track straight and breaking was substantially increased and the sense of traction and overall safety is what I feel this Honda Motorcycle should have. Based on my experience, I made the right choice and it was the best investment and I would buy the spring set again under the same circumstances. If considering suspension spring improvements, these are worth looking at. Happy riding!
The team at EPM is awesome! They have no issue answering questions and are great to interact with. They helped me dial in the tuning on my front forks.
Their team demonstrated exceptional technical expertise, diagnosing the issue quickly and recommending a precise rebuild tailored to our rider’s needs. Communication was clear and professional throughout the process—they kept us informed at every stage, from initial inspection to final testing.
Turnaround time was faster than expected.
Dropped them off in the morning and had them back by lunch. Great service and quality work.
What a difference! Bike never rode better
Bought this set a few years ago for an rt I picked up cheap. The shocks were both blown on it so after a bit of research, I bought this set.
Didn't think much about them, they worked and the bike was fun to ride.
Fast-forward a couple of years and I find a really clean rt with less than 30,000 for next to nothing. Riding that bike with the stock suspension was less than confidence inspiring. I switched the hyperpro stuff over to the new bike and it truly made a huge difference. I can happily grind the foot peg feelers around tight corners with confidence. The bike is now fun to ride. It's amazing how bad the stock shocks are or how good the Hyperpro units are? Either way I'm happy with these.
If you have an old rt with stock suspension buy these, the bike will become much more fun to ride.
Good experience from EPM, came recommended and did not fail. Took some 3rd party parts to install on my KTM 990 Adventure and did a great job plus servicing..
