At DMG Motorsports, we present the Vortex F5 Rear Sprocket, Aluminum 43T-520 Black Hardcoat (452AK-43) — a race-bred replacement sprocket built for Kawasaki riders who demand less rotating mass and more durability without sacrificing chain longevity. This is the same Vortex F5 design trusted at the track, delivering a stronger, quieter, and longer-lasting drivetrain component that drops noticeable weight versus a stock steel sprocket.

The F5 is CNC machined from 7075 T6 aluminum and finished with a PTFE black hardcoat that bonds to the aluminum surface to fight wear and reduce friction, all while giving the sprocket a clean, blacked-out look on your rear wheel. Vortex's patented tooth profile is engineered to improve concentricity and extend the life of both the sprocket and your chain, making this a smart upgrade whether you're building a track bike or simply replacing a worn OEM part.

This 43-tooth, 520-pitch sprocket is designed to fit a wide range of Kawasaki sportbikes, including the ZX-6R, ZX-7R/ZX-7RR, ZX-9R, Z1000, and Ninja ZX-10R across multiple model years, making it a popular choice for 520 conversion setups and direct OEM-pitch replacements alike.
