Vortex 150ZK-49 Black Aluminum Rear Sprocket 49T

The Vortex 150ZK-49 is a 49-tooth black anodized aluminum rear sprocket designed as a high-performance replacement or gearing upgrade for compatible motorcycles. Precision-manufactured in the USA, this sprocket delivers the lightweight durability and exact fitment that Vortex Racing is known for across street, track, and off-road applications.

Key Features:

• 49 Teeth — ideal for tuning final drive ratio for improved low-end acceleration and throttle response
• Black anodized aluminum construction — significantly lighter than OEM steel sprockets to reduce rotating mass
• 100% CNC machined in the USA from a specially formulated alloy per Vortex specifications
• Saber tooth groove design — Vortex patented tooth profile extends sprocket life and reduces chain wear
• Integrated mud grooves — help shed debris and keep the drivetrain running cleanly
• Anodized finish with contrasting machined silver accents for a race-ready appearance

Vortex aluminum rear sprockets are a popular choice for riders looking to fine-tune their gearing without sacrificing quality. The reduced rotational mass of an aluminum sprocket helps put more power to the ground and improves overall drivetrain efficiency. Always replace the front sprocket and chain simultaneously with the rear sprocket for optimal performance and longevity.
