After a 10 month long R&D process involving many iterations, we have come up with a new valving spec for our ND Xidas. Same great track & autox performance as before but vastly improved ride quality on the street. We have essentially increasing the damping adjustment range. Much more complicated than just sticking thinner shims in. We had to make a big increase in peak oil flow. That meant significant changes to to the internal parts. Many versions to get the right combination. Stoked with the result. Finally matched the exceptional ride quality of our NC Xida protos without giving up anything on the stiffer end of the damping range on track.

First batch of the new ND Xidas just sold out. Taking pre- orders for the next batch due mid August. We also switched from the previous 2.25" springs to 2.5" springs to reduce NVH.

Same long stroke as before, 126mm front, a whopping 180mm rear.
