At DMG Motorsports, we present the Vortex Rear Sprocket Aluminum 42T-520 Silver (435-42) — long recognized as the "Standard" in the race industry and trusted by champions across the paddock. This sprocket is engineered for riders who demand a lighter, stronger connection between engine and chain without sacrificing durability. CNC machined entirely in the USA from a specially formulated aluminum alloy, it delivers the reduced rotational mass that racers and trackday enthusiasts look for when shaving unsprung weight off their machine. The silver anodized finish not only looks sharp but also guards against corrosion, keeping the sprocket looking and performing like new ride after ride. Built to fit popular Kawasaki, Suzuki, and Yamaha models running 520-pitch chain, this 42-tooth sprocket is a proven, race-ready upgrade backed by Vortex's patented design.
