Vortex 614ZK-47 520 Aluminum Rear Sprocket 47-Tooth Black

The Vortex 614ZK-47 is a 47-tooth, 520-pitch black anodized aluminum rear sprocket designed for sport and performance motorcycles. Engineered and manufactured in the USA, this sprocket delivers a significant weight reduction over stock steel units, reducing rotating mass for sharper throttle response and improved acceleration.

Key Features:

• 47 teeth, 520 pitch — direct-fit replacement or performance gearing upgrade
• Black anodized finish — corrosion-resistant coating for long-lasting appearance and protection
• 100% CNC machined in the USA to precise tolerances for concentricity and consistent fit
• Specially formulated aluminum alloy per Vortex specifications for optimal strength-to-weight ratio
• Vortex patented tooth profile — unique design engineered to extend sprocket longevity and reduce chain wear
• Lightening holes reduce rotating mass without sacrificing structural integrity

The 614ZK-47 is part of Vortex Racing's comprehensive rear sprocket lineup, available in multiple tooth counts to allow riders to fine-tune their final drive gearing for track or street use. Adding teeth to the rear sprocket increases low-end acceleration and torque, while fewer teeth favor top-end speed. Always replace the front sprocket and chain simultaneously for even wear.
