The RENTHAL 428 R1 Works Chain (Part Number: C267) is engineered specifically for high-powered mini racing machines with up to 100cc capacity that utilize a 428 non-O-ring chain. This chain features shot-peened alloy steel side plates and extended bushings designed to reduce friction between the outer and inner link plates, maximizing power transmission for optimal performance. With an impressive average tensile strength of 4,496 lbs, this chain is built to withstand the demands of competitive racing. The case-hardened alloy steel bearing pins ensure maximum resistance to wear, while the gold-colored side plates provide an added layer of corrosion resistance. This chain is the perfect complement to Renthal sprockets, and it even includes a convenient clip-type link for easy installation.
