Vortex 201EZB-50 520 Steel Rear Sprocket 50-Tooth Black

The Vortex 201EZB-50 is a 520-pitch steel rear sprocket with a 50-tooth count, finished in an electroplated satin black coating for corrosion resistance. Engineered by Vortex Racing — a U.S.-based manufacturer with a proven track record in road racing, motocross, and supercross — this sprocket delivers the durability and precision demanded by both street riders and racers.

Key Features:

• 520 Pitch — Designed for use with standard 520 drive chains

• Carbon steel alloy construction — Manufactured to Vortex specifications for strength and longevity
• Electroplated satin black finish — Resists corrosion and provides a clean, aggressive appearance
• Hardened teeth — Case-hardened tooth profile withstands high mileage without sacrificing structural integrity
• Cupped-down face design — Body is stepped down from the tooth ring to reduce overall sprocket weight
• Patented tooth profile — Vortex's proprietary tooth geometry promotes even wear and extended sprocket life
• Precision manufactured — Tight tolerances ensure proper chain engagement and concentricity
