At DMG Motorsports, we present the Vortex F5 Rear Sprocket, 40T-520, Black Hardcoat for Kawasaki (Part# 452AK-40) — a race-proven upgrade for riders who demand less rotating mass and more durability from their final drive. Built by Vortex, a name trusted in Motocross, Supercross, and Road Racing paddocks worldwide, this sprocket swaps out your heavy OEM steel unit for a precision-machined aluminum piece designed to sharpen acceleration and handling without sacrificing longevity. Whether you're chasing lap times or just want a lighter, better-looking drivetrain component, this F5 sprocket delivers the performance edge Vortex is known for.

• 40-tooth, 520 pitch configuration engineered for Kawasaki applications
