At DMG Motorsports, we present the Vortex F5 Rear Sprocket, 43-Tooth, 530 Pitch, Black Hardcoat (840K-43) — a race-proven aluminum sprocket built to shed weight without sacrificing durability on your Yamaha. Vortex has long been a favorite among racers and serious street riders, and the F5 line delivers the strength, precision, and looks to match. This sprocket is finished in a jet-black hard anodized coat and treated with a PTFE overlay, giving it the kind of wear resistance and clean appearance that keeps your drivetrain looking sharp mile after mile.

Every F5 sprocket is 100% CNC-machined to look and perform its best, machined from 7075 T6 aluminum to a very high tolerance, ensuring tight, precise fitment and long service life. The distinctive tooth profile is engineered for smooth, reliable power transfer, and the hard anodized aerospace aluminum with a jet black dye results in an ultra light sprocket that stays cleaner and lasts longer. On top of that, the PTFE coating improves lubricity and durability, reducing friction and helping the sprocket resist grime buildup between the teeth. This is the trusted choice of champions, delivering race-team quality to your own machine.
