Vortex 775BZK-53 Black Aluminum 53-Tooth Rear Sprocket

The Vortex 775BZK-53 is a 53-tooth black anodized aluminum rear sprocket designed for high-performance street and track use. CNC-machined in the USA from aerospace-grade aluminum, this sprocket delivers a precision fit with reduced rotational mass for improved throttle response and power transfer.

Key Features:

• 53-Tooth rear sprocket for increased low-end torque and acceleration
• Black anodized finish (BZK designation) with CAT5 hardcoat treatment for enhanced durability and corrosion resistance
• Aerospace-grade aluminum construction reduces rotating mass compared to stock steel sprockets
• Vortex patented tooth profile engineered to extend sprocket and chain life
• 100% CNC manufactured in the USA to tight tolerances for precise chain engagement
• Designed for use with the matching chain pitch — verify pitch compatibility before installation

The Vortex 775BZK-53 is an excellent choice for riders looking to optimize acceleration and fine-tune gear ratios. The lightweight aluminum design helps free up horsepower by reducing drivetrain rotating mass, making it a popular upgrade over OEM steel sprockets for both street and motorsport applications.
