At DMG Motorsports, we present the Vortex CAT5 Rear Sprocket 46T-520 in Black for BMW (Part #193AZK-46) — a race-proven, lightweight aluminum sprocket engineered to replace your bulky OEM steel unit with a component built for serious performance. The Vortex CAT5 Series Rear Sprockets are anodized in color FIRST then CNC machined from 7075 aluminum to produce a trick colored sprocket with silver highlights. An aluminum sprocket is much lighter compared to OEM steel sprockets and this leads to reduced rotating mass and allows for improved acceleration and handling. Whether you're carving up the track or pushing hard on the street, this sprocket delivers the strength, precision, and head-turning style that serious BMW riders demand — all backed by the trusted service you get every time you shop with DMG Motorsports.
