At DMG Motorsports, we present the Vortex F5 Rear Sprocket in 46T-525 fitment, finished in black hardcoat and engineered specifically for BMW models like the S1000RR, S1000R, and S1000XR. Built by one of the most trusted names in racing hardware, this sprocket is designed to shed weight without sacrificing strength, giving your bike quicker acceleration and sharper handling every time you twist the throttle. Whether you're chasing lap times at the track or simply want a cleaner-running, longer-lasting drivetrain component on the street, this Vortex F5 sprocket delivers race-proven performance in a package that looks as good as it performs.

Each sprocket starts life as a billet of 7075 aluminum before being precision CNC machined to Vortex's exacting tolerances. Each sprocket is machined from 7075 T6 aluminum to a very high tolerance. The finishing process is what sets the F5 line apart: after hard anodizing with a jet black dye, Vortex then coats the sprocket with PTFE for added lubricity. The result is an ultra tough, ultra light sprocket that stays cleaner and lasts longer. This PTFE topcoat is applied after the teeth are cut, so the coating sits directly on the sprocket's teeth, and PTFE has a much lower coefficient of friction than raw aluminum and is also wear- and heat-resistant.

Compared to the stock steel sprocket, this aluminum unit trims significant rotating mass. The F5 Sprocket's aluminum construction makes it much lighter compared to an OEM steel sprocket and this leads to reduced rotating mass and allows for improved acceleration and handling. Backed by a manufacturer known for outfitting championship-winning teams, this 46-tooth, 525-pitch sprocket (Vortex part 193K-46) is a direct-fit upgrade for compatible BMW models.
