At DMG Motorsports, we present the Vortex F5 Rear Sprocket 44T-520 in Black Hardcoat (193AK-44) — a race-bred, aluminum rear sprocket engineered for BMW riders who demand strength, precision, and reduced rotating mass. Vortex has long been a trusted name on the podium, and this F5 sprocket delivers the same championship-level engineering to your street or track build, converting your BMW to a 520 chain setup while keeping weight to a minimum.

Each sprocket is CNC machined from 7075 aluminum for an exceptional strength-to-weight ratio, then finished with a jet black hard anodizing process and a PTFE topcoat that boosts lubricity and wear resistance. The result is a sprocket that not only looks aggressive in black, but also sheds unsprung and rotating weight compared to a stock steel sprocket, helping to sharpen acceleration and handling. Backed by Vortex's reputation for precision manufacturing and championship-winning performance, this 44-tooth, 520-pitch rear sprocket is ready to bolt on and perform.

Features:

• CNC machined from 7075 aluminum for outstanding strength and light weight
• Hard anodized with a jet black dye for a stealthy, aggressive finish
• PTFE hardcoat added for increased lubricity, wear resistance, and easier cleaning
• Unique, patent-pending tooth design engineered for longevity and smooth power transfer
• Lighter than an OEM steel sprocket, reducing rotating mass for improved acceleration and handling
• 44-tooth, 520-pitch configuration for BMW S1000RR/S1000R/S1000XR platforms
• Trusted by champions and built to Vortex's exacting race-quality tolerances
