The Vortex 604ZB-53 is a 53-tooth black anodized aluminum rear sprocket from Vortex Racing, built for riders who demand precision gearing and reduced rotating mass. Designed to fit the 604 carrier bolt pattern, this sprocket is CNC-machined to exact tolerances for consistent, reliable performance on the street or track.

Key Features:

• 53-Tooth rear sprocket for aggressive acceleration-focused gearing
• Black anodized (ZB) aluminum construction for lightweight performance and corrosion resistance
• 604 carrier bolt pattern for direct fitment on compatible motorcycle models
• CNC-manufactured in the USA to precise tolerances for concentricity and quiet operation
• Reduces rotating mass compared to steel sprockets, improving throttle response and power delivery
• Induction-hardened tooth profile for extended sprocket life

Vortex Racing rear aluminum sprockets are a trusted choice among racers and performance street riders. The lightweight construction minimizes rotational inertia, translating engine output more efficiently to the rear wheel. The black anodized finish provides both a clean aesthetic and added protection against the elements.
