Vortex 775ZB-48 Black 48-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 775ZB-48 is a 48-tooth, 520-pitch aluminum rear sprocket finished in a durable black hard-coat anodized coating. Precision-engineered for performance-oriented street and track riders, this sprocket is part of Vortex's renowned CAT5 lineup and is 100% CNC machined in the USA to exacting tolerances.

Key Features:

• 48 Teeth / 520 Pitch — Direct-fit replacement or gearing upgrade for 520-chain applications
• Black Hard-Coat Anodized Finish — Enhanced surface hardness for extended wear life and corrosion resistance
• Lightweight Aluminum Construction — Specially formulated alloy per Vortex specifications; significantly lighter than OEM steel sprockets to reduce rotating mass
• 100% CNC Machined in the USA — Manufactured to tight tolerances ensuring perfect concentricity on every sprocket
• Vortex Patented Saber Tooth Design — Unique tooth geometry reduces chain drag and friction for improved acceleration and deceleration response
• Lightening Holes — Strategically placed cutouts further reduce rotating weight without sacrificing structural integrity

Reducing rotating mass at the sprocket translates directly to improved throttle response and quicker acceleration. The black hard-coat finish provides a two-tone machined aesthetic while delivering superior durability compared to standard clear-anodized aluminum sprockets. Available in single-tooth increments to allow precise gear ratio tuning.
