At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in 41-Tooth, 520 pitch, Black finish (Part #251AZK-41) — a race-proven upgrade for your Honda that swaps out the heavy OEM steel sprocket for a lightweight, precision-engineered aluminum component built for serious performance. Vortex has long been a favorite among racers and track-day riders, and this CAT5 sprocket brings that pedigree straight to your bike with a striking black anodized finish, bright silver machined highlights, and a design engineered to hold up to the demands of hard acceleration and repeated shifting.

Unlike sprockets that are anodized after machining, Vortex anodizes this sprocket in color first and then CNC machines it from 7075 aluminum, so the black finish is set into the material itself while the machining process reveals crisp silver highlights along the cut edges. The result is a sprocket that looks as aggressive as it performs, with a reduced rotating mass compared to a stock steel sprocket that helps improve acceleration and handling. The unique saber tooth groove design is engineered to increase sprocket longevity and chain engagement, and every Vortex sprocket is built to the brand's own specially formulated alloy specifications for consistent strength and durability.
