The Vortex 491AZK-52 is a 52-tooth aluminum rear sprocket finished in a striking black anodize with contrasting silver machined accents. Designed for serious street and track riders, this sprocket is built to Vortex Racing's exacting standards and manufactured entirely in the USA.

Key Features:

• 7075 T6 billet aluminum construction — aerospace-grade alloy per Vortex specifications for maximum strength at minimum weight
• 100% CNC machined in the USA to the tightest tolerances
• Black anodized finish with contrasting silver machined accents — the "AZK" color designation
• Patented saber tooth groove design — unique tooth profile that increases sprocket longevity and reduces wear
• 52-tooth rear sprocket — higher tooth count lowers overall gearing for improved low-end torque and acceleration
