At DMG Motorsports, we present the Vortex Aluminum Rear Sprocket 43T-525 in Silver (part number 252-43) — the sprocket that's become known as the standard-bearer in the race industry. Built for riders who demand a durable, lightweight upgrade over stock steel sprockets, this Vortex 525-pitch, 43-tooth rear sprocket is a direct fit for Honda CBR600 models, including the CBR600 F4i and CBR600RR generations. Swapping to an aluminum sprocket cuts unsprung and rotating mass, helping your bike accelerate harder and change direction more crisply than it can with a heavier OEM steel sprocket.

Vortex has earned its reputation on the track, and this CAT5-style silver sprocket carries that pedigree straight to your driveline. Each sprocket is precision CNC machined and finished with Vortex's unique tooth profile designed to work smoothly with your chain for consistent power delivery and reduced wear. Whether you're chasing lap times or simply want a proven, race-bred replacement sprocket, the Vortex 252-43 delivers the strength-to-weight ratio and fitment confidence that champions have relied on for years.
