Vortex 255B-55 Black Aluminum Rear Sprocket 55-Tooth

The Vortex 255B-55 is a 55-tooth black anodized aluminum rear sprocket engineered for high-performance street and track applications. Precision CNC-machined in the USA from aerospace-grade aluminum alloy, this sprocket delivers an ideal balance of lightweight performance and long-term durability.

The black hard-coat anodized finish provides superior corrosion resistance and surface hardness compared to standard anodizing, helping the sprocket maintain its appearance and integrity through extended use. The 55-tooth count provides a taller gear ratio on the rear wheel, making it a popular choice for stunt riding, enhanced low-end torque, and quicker off-the-line acceleration.

Key Features:

• 55-Tooth rear sprocket for increased low-end torque and acceleration
• Black hard-coat anodized finish for corrosion resistance and extended service life
• CNC machined from high-strength aerospace-grade aluminum alloy
• Lightweight construction reduces rotating mass for improved throttle response
• Optimized tooth geometry for smooth chain engagement and reduced wear
• 100% manufactured in the USA by Vortex Racing
