At DMG Motorsports, we present the Vortex Steel Rear Sprocket (Part# 454S-40) — a 40-tooth, 525-pitch replacement sprocket engineered for select Kawasaki models that demand dependable, race-proven durability. Vortex builds every sprocket from high tensile carbon steel and finishes it in a satin black electro-plated coating that stands up to corrosion while looking great on the bike. Each unit is precision CNC machined individually to hold the tightest tolerances, so you get consistent chain engagement, smoother power delivery, and long-lasting performance whether you're commuting, touring, or turning laps at the track.

Vortex's Ideal Tooth Design™ is engineered specifically to optimize chain hold and release, reducing wear on both the sprocket and chain over time. Hardened teeth add extra durability for high-mileage riding, and the sprocket is cupped down to shed unnecessary weight without sacrificing strength. This 454S-40 sprocket is designed as a direct-fit replacement for compatible Kawasaki sportbike platforms, including certain ZX-7R and ZZ-R600 models, making it easy to restore or upgrade your drivetrain with genuine Vortex quality.
