Vortex sprockets are trusted at every level of motorcycle racing, and this CAT5 series rear sprocket brings that same championship-grade engineering to your Honda. Anodized first and then precision CNC machined, this sprocket delivers a striking blue finish with bright silver highlights that make your bike stand out on the grid or the street, while its lightweight aluminum construction helps reduce rotating mass for snappier acceleration and sharper handling compared to a heavy OEM steel sprocket.
