Vortex 201ZB-40 Black 40-Tooth 420 Rear Sprocket

The Vortex 201ZB-40 is a 40-tooth, 420-pitch aluminum rear sprocket finished in a black anodized coating. Engineered for competitive motocross and off-road applications, it delivers a precise balance of reduced rotating mass and long-term durability.

Key Features:

• 40 Teeth – optimized tooth count for acceleration and top-end balance
• 420 Chain Pitch – matches standard 420 chain systems common to off-road and mini-bike platforms
• Black Anodized Finish – corrosion-resistant hard-coat anodizing for lasting appearance and surface durability
• 7075-T6 Billet Aluminum Construction – lightweight aerospace-grade aluminum reduces drivetrain rotating mass
• Vortex Patented Tooth Design – proprietary geometry promotes smooth chain engagement and extended sprocket life
• Precision CNC Machined – manufactured to tight tolerances for true concentricity and consistent fitment
• Lightening Holes – strategically placed cutouts further reduce weight without compromising strength
