At DMG Motorsports, we present the Vortex F5 Rear Sprocket 45T-525 Black HC (435CK-45) — a race-bred aluminum sprocket built to shed weight, hold up to abuse, and look sharp doing it. Designed as a lightweight alternative to the stock steel unit, this F5 sprocket helps cut rotating mass at the rear wheel, which translates into snappier acceleration and improved handling without sacrificing strength. Fitting select Kawasaki, Suzuki, and Yamaha models with a 525 chain, it's the kind of upgrade that serious riders and racers reach for when every ounce and every millisecond counts.

Vortex has built its reputation by supplying components trusted by professional race teams, and this F5 sprocket carries that same pedigree. Each sprocket is machined from 7075 T6 aluminum to a very high tolerance. It's 100% CNC manufactured in the U.S.A. from a specially formulated alloy per Vortex specifications. The black hard-coat finish isn't just for looks — after type 3 hard anodizing with a jet black dye, Vortex then coats the sprocket with PTFE for added lubricity. This combination results in a sprocket that stays cleaner, wears slower, and keeps its edge lap after lap.
