Vortex 313ZL-54 Rear Sprocket 520 Pitch 54-Tooth Zinc Aluminum

The Vortex 313ZL-54 is a 54-tooth, 520-pitch rear sprocket machined from high-grade aluminum alloy, designed for sport and performance motorcycle applications. As part of Vortex Racing's industry-leading rear sprocket lineup, this sprocket delivers the ideal combination of lightweight construction, precision fit, and long service life.

Key Features:

• 520 Pitch: Compatible with standard 520-series drive chains
• 54 Teeth: Higher tooth count suited for increased low-end torque and improved acceleration
• Aerospace-grade aluminum construction reduces rotating mass for improved throttle response and power transfer
• Zinc/silver anodized finish provides corrosion resistance and a clean, classic appearance
• 100% CNC manufactured in the USA to tight tolerances for precise chain engagement
• Vortex patented tooth profile for extended sprocket longevity
• Direct bolt-on replacement — no modifications required

Vortex Racing rear sprockets are a top choice among road racers and performance street riders. The lightweight design directly reduces rotational mass, helping deliver more usable power to the rear wheel. The 54-tooth configuration provides a numerically higher gear ratio, making it an excellent choice for riders seeking stronger acceleration and improved low-end performance. Always ensure the front sprocket and chain are the same 520 pitch when completing a drivetrain service or conversion.
