At DMG Motorsports, we present the Vortex CAT5 Rear Aluminum Sprocket in 47T, 520 pitch, blue anodized finish for Honda applications (part number 251AZB-47) - a race-bred upgrade built to shed weight and add attitude to your ride. Vortex has long been a favorite among racers and street riders alike for sprockets that combine eye-catching color with genuine performance benefits, and this CAT5 sprocket carries that reputation forward.

This sprocket is anodized first, then precision CNC machined from aircraft-quality 7075 aluminum, so the milling process exposes bright silver highlights against the vivid blue background for a striking two-tone look that turns heads even when the bike is parked. Beyond the aesthetics, the lightweight aluminum construction trims rotating mass compared to a heavy OEM steel sprocket, which helps sharpen acceleration and handling. Vortex's signature saber tooth groove design is engineered into the tooth profile to extend sprocket longevity, and the overall pattern reflects a design that's been proven in competition for years.
