At DMG Motorsports, we present the Vortex 251A-48 Aluminum Rear Sprocket — a 48-tooth, 520-pitch silver sprocket built for Honda sportbike riders who demand race-proven hardware without the compromise. Vortex has long been regarded as the benchmark in the sprocket industry, and this 251A model carries that reputation onto CBR600F4i, CBR600RR, CBR929RR/954RR, CBR1000RR, and RC51 platforms, giving you a durable, precision-engineered 520 conversion piece that drops rotating weight right where it matters most. Whether you're chasing lap times at the track or simply want lighter, sharper acceleration on the street, this sprocket delivers the strength-to-weight ratio serious riders rely on.
