Our 420SH and 428 SHDR provide this same winning performance for smaller-displacement bikes. The 520MRD chain is also available in colors to match your bike (see page 3). Anyone with a Hayabusa, ZX-12 or one of the new generation of 180hp literbikes knows how hard they are on chains. EK steps up with an incredibly strong Quadra-X Ring chain that has proven its superiority in controlled lab tests. ZVX chains are also great for any bike thats been modified for more-than-stock horsepower. The 530ZVX is available in colors (see page 3). We strongly recommend these Quadra-X Ring chains as the ideal replacement for the original equipment chain on your 600 to 1000cc sportbike. Features like solid bushings, lightening holes in the sideplates, large-diameter pins, and frictionreducing Quadra-X Rings help ensure high-performance and durability. MVX chains are available in colors (see page 3). Zero Stretch Technology is available as an option with MVXZ chains.
