At DMG Motorsports, we present the Vortex Steel Rear Sprocket 42T-520 in Black (P/N 3-435S42) — a heavy-duty, race-proven replacement sprocket engineered for riders who demand durability and precise power transfer from their Kawasaki, Suzuki, or Yamaha. Vortex has built its reputation on the track, and this rear sprocket is manufactured to the same exacting standards trusted by professional race teams around the world. Whether you're running stock gearing or dialing in a custom ratio, this 520-pitch, 42-tooth sprocket delivers long-lasting performance without sacrificing strength.

Each sprocket is cupped down from the tooth ring to the body to shed unnecessary weight while maintaining structural integrity, and it's finished with a satin black electro-plated coating that stands up to the elements. Hardened teeth mean this sprocket is built to rack up the miles without compromising strength, making it an excellent choice for street or track use.
