Let customers speak for us
Everything seems great l have just finished installing them, but where l live there is about 2 ft of snow, so I have booked holidays for March 1 and trailering to Texas , can’t wait to try them.
EMP delivered a good product at a reasonable cost without any issues. Thank you for being so responsive and reliable.

Nice improvement over stock. Compression and rebound adjustments that work along with preload. Bike sits taller with new stock height cartridges. Firmer more controlled ride.
Excellent customer service received my shock in 1/3 of the time promised excellent packaging… felt like a kid opening my first toy
The product is great and wasn't expected to receive it so fast. I thought it would've taken at best 45 days but instead received it in a litte over 3 weeks and installed it right away.product is very high quality and was set to all specs according to questions asked prior to ordering to ensure it fits both me and my bike. I would recommend them to everyone. Thanks EPM for an amazingly high quality product. Your product matches your services. Thanks again!
Respond much better for me when front brakes are applied and the curves
EPM took care of me.
Quick ship. Great product. Economical way to fix my front end dive and more.
Exactly what I was looking for. Greatly reduce brake dive. Stabilized slow sped maneuvers. Precise cornering and stabilized two up riding.

I LOVE IT! Just enough to have one foot flat. Its also quite pretty in a subtle, not too girly way.
Exactly what I needed for my tired original springs, fit perfect, shipping was spot on and they kept me informed along the way.
