At DMG Motorsports, we present the Vortex F5 Rear Sprocket 43T - 530 Black (438K-43), a race-bred aluminum rear sprocket built to shed weight without sacrificing durability on your Kawasaki, Suzuki, or Yamaha. Vortex has long been a favorite among racers, and this F5 hardcoat sprocket brings that championship-winning technology straight to your drivetrain, delivering crisp power transfer, reduced rotating mass, and a striking jet-black finish that sets your bike apart from the crowd.

Vortex's F5 hardcoat design is engineered so the PTFE coating is applied directly to the sprocket's teeth after machining, ensuring maximum durability where it matters most. As Vortex explains, the F5 Hardcoat is applied after the sprocket is cut, allowing the Polytetrafluoroethylene (PTFE) coating to sit on the sprocket's teeth, and PTFE has a much lower coefficient of friction than raw aluminum while also being wear- and heat-resistant. This translates to a longer-lasting sprocket that reduces drivetrain friction loss compared to standard aluminum options.

This particular 438K-43 fitment is a Black aluminum, 530-pitch, 43-tooth rear sprocket designed as a direct-fit upgrade for a wide range of Kawasaki, Suzuki, and Yamaha models, including select Suzuki GSX-R1000, GSX-S1000, and Yamaha FZ-09, FZ-10, MT-07, and XSR900 platforms, among others.
