Vortex 110B-59 520 Steel Rear Sprocket 59-Tooth Black

The Vortex 110B-59 is a 520-pitch, 59-tooth steel rear sprocket finished in a satin black electro-plated coating for superior corrosion resistance. Engineered by Vortex Racing — a U.S.-based manufacturer with a long-standing reputation in motocross, supercross, and road racing — this sprocket delivers the precision and durability demanded by serious riders.

Key Features:

• 520 Pitch: Designed for use with standard 520-series chain
• 59 Teeth: Higher tooth count for increased low-end torque and acceleration
• Carbon Steel Construction: Made to precise Vortex specifications for concentricity and long-term durability
• Black Electro-Plated Finish: Satin black coating resists corrosion and provides a clean, aggressive look
• Hardened Teeth: Heat-treated teeth stand up to demanding riding conditions without sacrificing structural integrity
• Lightening Holes: Strategic cutouts reduce rotating mass for improved performance
• Patented Tooth Design: Vortex's unique tooth profile increases sprocket longevity compared to standard designs
• Precision Machined: CNC-manufactured for consistent quality and exact fitment

The 110B series steel sprocket is an excellent choice for riders who prioritize durability and longevity over the weight savings of aluminum. The black hard-coat finish provides lasting good looks alongside reliable corrosion protection, making it well-suited for both street and off-road applications.
