Let customers speak for us
They got me all the right parts and explained what was going on. So glad I did not do myself
Finally adjustable front forks that should not bottom out.
No more pogo stick, looking forward to some tougher riding.
Was able to bring the bike in and they did their magic while I waited
Changed the ride completely. Much more planter in corners and rebound way improved on bumpy roads
I'll start with the first ride with my wife. She said much better on the queen seat on the CVO Limited. I think they work fantastic. Now I only have the rear shocks on currently. They were the easiest to install and I'm still riding. By sending in the weights and the percentages, the shock were pre-set at the factory. A quick measurement when the bike was off the ground and a check after install of the bike and me was exactly 20mm. No adjustment needed. Also noticed when my wife got on the bike when down some, but at the next stop sign when I put my feet down they were in the same position at when I was on it by myself.
Putting the fork springs in and changing the seals next week. Should be even better. We're in New England so getting cold.
The best part was the 10% off in October. Fantastic. Great doing business with EPM and Wilber. Thank you
Exactly what I needed, my factory spring was too soft. This progressive piece is a little bit firmer and allows my suspension to not bottom out. Thank you!
Perfect fit, perfect replacement for the factory Showa. 1993 BMW R100R rides like new again!
Very high-quality shocks. Pricing is reasonable for what you get. Super easy install. Highly recommend.
I tried two after market rear shocks on my‘23 Road Glide and wasn’t pleased at all with either set. My wife gave me an evil eye when I-told her I had ordered another set (3rd set) of shocks. About an hour into our first ride on the Wilbers she acknowledged the Wilbers were a huge improvement.
The shocks are very easy to install and make the ride as smooth as can be.
Fantastic upgrade that really improves the ride.
Can’t rave enough about the set-up! Two weeks after installation, I went on a 9 day ride from Staten Island NY to Key West FL and back, with various stops in between. The bike handled so smoothly, it was the best long ride i ever had. Never bottomed out either! I’ve been recommending the Wilber’s Nivomat suspension & EPM Performance to everyone I meet. Thank you.
