Great experience with epm
I wish I bought these sooner.
Easy to find my needed part and ordering was painless.
Completely changed how the bike rides! It is awesome again, no wobble or bobbing and transitions are just normal events again. extremely happy with purchase!
I was happy to recieve the forks, they looked Brand New.
The rebuilt forks came back in very nice clean shape. Thank you
Exactly what I was looking for
Easy install, great springs, and I also ran the recommended Wilbers fork oil. The ride is fantastic. These combined with the YSS rear shocks make the bike handle on another level. Very happy with the result! EPM was super great to work with and highly recommend them!
They look FANTASTIC. I picked up chrome springs to go over the black shocks and they look retro-modern on my '75 Z1. The ride is great, and I LOVE the amount adjustment. Worth every penny. Note to future 75' Z1 owners, had to notch my chain guard to accommodate the shock, I run an OEM style chain guard. I also made spacers on the top mounts of shocks b/c I did not put my grab bar back on. The space for running the grab bar with these shocks is VERY tight, not sure its even doable. I was planning to not run a grab bar regardless. I also changed chain sizes from 630 to 530 (again, a planned change) to also increase clearances from the shocks.
The bike rides like a dream once I got everything dialed in, my only regret was not doing it sooner. Well worth the money.
My Wilber shocks and the front fork springs have made a major difference in the way the bike rides nc750x DCT. It's confidence, producing and makes the ride so much more enjoyable. It's like a different bike
The service on my shock was outstanding. Great communication before, during and after the service. The performance of the shock is greatly improved. Good stuff!
Excellent performance suspension
Very adjustable. Took care of my high speed wobble
Transformed the Ktm superduke 1390. Highly recommended!
