At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Black, model 435ZK-42 — a 42-tooth, 520-pitch aluminum sprocket engineered for riders who demand race-bred performance without sacrificing style. Fitting select Kawasaki, Suzuki, and Yamaha models, this sprocket is part of Vortex's renowned CAT5 lineup, trusted by champions on the track and street alike. Vortex anodizes each sprocket in color first, then CNC machines it from 7075 aluminum, leaving behind a striking black finish accented with brilliant silver highlights along the machined surfaces. The result is a sprocket that looks as fast as it performs.

Swapping to this lightweight aluminum sprocket reduces rotating mass compared to a heavier OEM steel unit, which can translate into quicker acceleration and sharper handling response. Vortex backs this up with its patented, unique tooth design that helps the sprocket resist wear and extend service life under hard use. Every sprocket is precision CNC machined in the USA from a specially formulated aluminum alloy to Vortex's own specifications, ensuring consistent quality and a confident, secure chain fit.
