At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Aluminum, 48-Tooth, 520 pitch, finished in bold Blue for Honda applications (Part# 251AZB-48). Built for riders who want race-proven performance and a striking visual upgrade, this sprocket is anodized first and then precision CNC machined from 7075 aircraft-grade aluminum, revealing a vivid colored face with contrasting silver highlights where the material is cut away. The result is a sprocket that looks as fast as it performs, dropping rotating mass compared to a heavy OEM steel sprocket for snappier acceleration and sharper handling.
Vortex has built its reputation in the paddock, and its CAT5 sprockets are trusted by champions for their combination of strength, light weight, and long service life. The unique saber-tooth design isn't just for looks - it's engineered to increase sprocket longevity while keeping the chain running smoothly through every gear change. Whether you're chasing lap times or simply want a lighter, better-looking sprocket for your street bike, this Vortex CAT5 unit delivers proven race-inspired engineering in a direct-fit 520 conversion package for compatible Honda models.
