At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 42T-525 in Silver (454-42) — the "Standard" in the race industry and a proven favorite among Kawasaki sportbike owners and racers alike. Built to Vortex's exacting specifications, this sprocket delivers the ideal blend of reduced rotational weight and race-ready durability, helping your Kawasaki accelerate harder and shift gears with a lighter, more responsive feel. Whether you're chasing lap times on the track or simply want a sharper-looking, better-performing drivetrain component on the street, this Vortex sprocket is engineered to hold up to serious abuse while keeping unsprung weight to a minimum.

Each sprocket is CNC machined from 7075 aluminum for outstanding strength without unnecessary bulk, then finished in a durable silver anodized coating to help resist corrosion and keep it looking sharp ride after ride. Vortex's proprietary tooth profile is designed to extend sprocket life and provide smooth, consistent chain engagement, and the patented design has made Vortex sprockets a go-to choice trusted by champions across multiple forms of motorcycle racing. This particular 454-42 sprocket is a 42-tooth, 525-pitch fitment produced for a wide range of Kawasaki models, including ZX-6R, ZX-7R, ZX-7RR, ZX-9R, ZX-10R, Z1000, and ZZR600 platforms across various model years.
