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.
Everything fix perfect and replaced my tired worn out original shock, shipping was spot on and they kept me informed all along the way.
Great customer service and a timely return, considering I am at the other end of the country. The shock seems to be working as good as new. I would highly recommend using this company and will use them if and when my rear shock goes bad.Thanks again
