The Vortex 611ZB-49 is a 49-tooth black steel rear sprocket engineered for motorcycle riders who demand durability and precision in their drivetrain. Built to Vortex's exacting standards, this sprocket is manufactured from carbon steel alloy and finished with an electro-plated satin black coating to resist corrosion and maintain a clean appearance over time.

Key Features:

• Satin black electro-plated finish – corrosion-resistant coating keeps the sprocket protected and looking clean
• Hardened teeth – heat-treated tooth profiles withstand extended mileage without sacrificing structural integrity
• Cupped body design – sprocket is cupped down from the tooth ring to the body to reduce overall weight without compromising strength
• Patented tooth geometry – Vortex's unique tooth profile promotes smooth chain engagement and extends sprocket service life
• 49-tooth rear sprocket – higher tooth count for increased low-end acceleration and improved throttle response
