At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 43-Tooth, 530 pitch, finished in black for select Yamaha applications (Part #3-840ZK43). This is the sprocket that racers reach for when they want to shed unnecessary rotating mass without sacrificing durability. Vortex builds its CAT5 line by anodizing the aluminum first and then CNC machining it, a process that leaves behind a striking black finish accented with bright silver highlights wherever the material is cut. The result is a sprocket that looks as fast as it performs, backed by a design pedigree that has been proven on the track and trusted by champions.

Swapping to this lightweight aluminum sprocket reduces rotating mass compared to a heavier OEM steel sprocket, which helps improve acceleration and handling on your Yamaha. Every CAT5 sprocket is precision CNC manufactured in the USA from a specially formulated alloy engineered to Vortex's own specifications, and finished with a unique tooth design intended to extend service life. If you're upgrading your drivetrain for the street or the track, this Vortex CAT5 43T-530 sprocket delivers the look, the performance, and the reliability that has made Vortex a staple in powersports racing.
