At DMG Motorsports, we present the Vortex F5 Rear Sprocket 46T-520 Black Hardcoat for Yamaha (840AK-46) — a race-proven, drop-in upgrade engineered to shave rotating mass while standing up to the abuse of hard riding and racing. Vortex has built its reputation on precision-machined components trusted by professional teams, and this F5 sprocket brings that same championship-level engineering to your Yamaha's drivetrain. Its hard anodized black finish with a PTFE topcoat not only looks aggressive but actively fights wear, corrosion, and chain grime, so you spend less time cleaning and more time riding.
