Check out the new RK MXU Sealed Ring Racing Chain. Its life expectancy is more than double that of non-sealed chains, as the seal keeps dirt out and lube in. Additional lube guarantees performance at the end of grueling moto — not just at the start. The thin UW seal keeps the weight low, reducing the rotational mass when compared to a standard sealed chain. Small seal contact points eliminate drag, and the Master Link incorporates a non-press side plate for slide on installation. Ideal for professional level 125cc to 500cc open class racing, MXU chains have a maximum tensile strength of 9,000 pounds per 100 links. Retail runs $116.03 for 120 links.

During testing Eibach's engineers felt that the RZR PRO R 4 Ultimate felt great out of the box but could use an improvement on low-speed bump chops and was prone to bucking over whoops. With adjustments to the combined spring rate and crossovers, Eibach is proud to have achieved a smooth and planted ride.
