At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 454-40 — a 40-tooth, 525-pitch silver sprocket engineered for riders who demand race-proven durability without the weight penalty of steel. Vortex has long been considered the standard in the racing industry, and this sprocket carries that reputation into your Kawasaki's drivetrain, delivering crisp power transfer, reduced rotating mass, and a finish that looks as good as it performs.

Machined entirely in the USA to Vortex's own specially formulated alloy, this sprocket is built to hold up to aggressive street and track use while shaving unsprung weight compared to a factory steel unit. Its patented tooth geometry is engineered specifically to extend chain and sprocket life, so you get both performance and longevity in one component. Whether you're chasing lap times or just want a lighter, better-looking drivetrain upgrade, this Vortex sprocket delivers the fit, finish, and strength that champions rely on.
