Wilbers Fork Spring - Zero friction - Progressive
Wilbers progressive fork springs — ZERO Friction finishing
Our vibratory finishing process (trough vibrator with tailored media) micro-polishes the spring surface. The resulting fine, shiny finish reduces surface roughness and friction — hence ZERO Friction. Pair with our specially formulated Wilbers fork oil and the specified air chamber for your vehicle to maximize performance.

Let customers speak for us
Friendly competent service. Well priced and fast turn around. Definitely recommend for GS owners.
I bought this damper on a whim for a 1290 Super Duke GT. It improved the mid-corner rough pavement composure of this bike immensely. If I’d have known how profound the improvement would be, I’d have had this on the bike day one
Great Product! I've had the Wilbes Nivomat Suspension installed on my two bikes.
Installed and immediately had a more solid ride. (Got the front springs too, but didn’t have time to install yet … ) Just returned from a 1,000 round trip to the NC mountains with 95 +/- lbs of gear. Adjusted the preload just a hair and it was AWESOME! Cant say enough great things. Great product!
Excellent quality product . The ride is much-better
Solid and smooth , no more front end dive when front brake applied.
This kit effectively lowered a 2011 BMW R1200GS. This in combination with a low seat that was already on the bike when purchased has transformed this into a much more enjoyable ride. The bike handles much better now as well as allowing me to be comfortably be flat-footed when stopped or maneuvering the bike around the garage. Springs arrived sooner than excepted.
I'm a shorter rider (5'4") and have sent OEM rear shocks for two different bikes to EPM for modification to lower the bikes for better reach. Although different people warned me not to lower my bikes, I'm glad I trusted my gut and did what was best for ME! EPM helped me out and allowed me to ride and handle my bikes with more ease and confidence! No more drops due to the bikes being too tall (and me too short)! Service has been great and very helpful!
