At DMG Motorsports, we present the Vortex F5 Rear Aluminum Sprocket 48T-520 Black Hard-Coat for Yamaha (840AK-48) - a race-proven drivetrain upgrade built to shed weight without sacrificing durability. Machined from premium 7075 aluminum and finished with a jet-black hard anodized coating, this sprocket delivers the strength-to-weight ratio serious riders demand, whether you're chasing lap times on the track or looking for a long-lasting replacement for the trail. The added PTFE coating helps the sprocket run cleaner and last longer by reducing friction and resisting grime buildup, so you spend less time cleaning and more time riding.
