The Vortex CK7210 is an HFRS "Hyper Fast" 520 conversion chain and sprocket kit featuring aggressive quick-acceleration gearing — one tooth down in front and two teeth up in the rear — paired with a laser-cut steel rear sprocket and Vortex RX3 X-ring chain. This complete kit delivers a significant upgrade over stock drive components for street and performance riding applications.
