At DMG Motorsports, we present the Vortex F5 193AK-46 Rear Sprocket — a 46-tooth, 520-pitch aluminum sprocket engineered as a lightweight, race-proven upgrade for compatible BMW models. Built to Vortex's exacting racing standards, this sprocket combines serious strength with reduced rotating mass, helping your bike accelerate harder and handle better than it does with a heavier factory steel sprocket. Finished in a striking jet black hard-coat with a PTFE topcoat, it delivers both aggressive good looks and long-term durability, making it a favorite among racers and street riders who demand performance without compromise.

Features:

• CNC machined from 7075 aluminum for amazing strength and light weight
• Hard anodized with a jet black dye for a durable, aggressive finish
• PTFE coated for added lubricity, reduced wear, and easier cleaning
• Unique tooth design engineered to increase sprocket longevity
• Lighter aluminum construction reduces rotating mass for improved acceleration and handling versus OEM steel
• 100% CNC manufactured to tight tolerances for precise, reliable fitment
• 520-pitch, 46-tooth configuration; sold in Vortex's signature black finish
• Trusted by champions and used across professional racing applications
