At DMG Motorsports, we present the Vortex F5 Rear Sprocket 40T-530 Black Hardcoat (840K-40) — a race-proven, lightweight aluminum sprocket engineered for Yamaha models running a 530 chain. Built for endurance and precision, this sprocket is the trusted choice of champions who demand consistent power delivery without unnecessary rotating mass. Vortex's signature manufacturing process combines aerospace-grade materials with a striking jet-black hardcoat finish, giving your bike a clean, aggressive look while standing up to the abuse of hard riding and racing.

Each F5 sprocket is CNC machined from 7075 aluminum, then hard anodized with a jet black dye and finished with a PTFE coating to boost lubricity and wear resistance. The result is an ultra-light sprocket that stays cleaner, runs quieter, and lasts longer than standard steel or unfinished aluminum alternatives. Vortex's patented tooth design further extends sprocket life by reducing chain wear and improving power transfer, making this a smart upgrade for street riders and racers alike.
