At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket in Blue — a 44-tooth, 530-pitch aluminum sprocket engineered for Honda models like the CBR600 and CBR1000RR. This is far more than a bolt-on replacement part; it's a race-proven upgrade built by a company whose components have been put to the test by some of the world's most respected champions and teams. Every 251ZB-44 sprocket is anodized first, then precision CNC machined so the color pops through with striking silver highlights on the machined surfaces — giving you a sprocket that looks as fast as it performs. Cut from lightweight aluminum instead of heavy OEM steel, it sheds rotating mass to sharpen acceleration and handling, while Vortex's patented saber tooth groove design increases sprocket longevity for lasting performance on the street or track.
