Vortex 435ZK-46 CAT5 Black Aluminum 46-Tooth 520-Pitch Rear Sprocket

The Vortex 435ZK-46 is a lightweight CAT5 aluminum rear sprocket engineered for performance motorcycle riders who demand precision, durability, and reduced rotating mass. Manufactured entirely in the USA on CNC equipment, this 46-tooth, 520-pitch sprocket is built to exacting tolerances from a specially formulated aluminum alloy developed to Vortex's own specifications.

Key Features:

• CAT5 aluminum construction — specially formulated alloy per Vortex specifications for an optimal strength-to-weight ratio
• 100% CNC manufactured in the USA for consistent concentricity and precise fit
• Patented Saber Tooth groove design — unique tooth profile that extends sprocket longevity and reduces chain wear
• Black hardcoat finish with PTFE — color anodizing applied to the body while sweeps, mud grooves, and teeth retain a contrasting silver machine-cut finish
• Lightening holes reduce overall rotating mass for improved throttle response
• 46 teeth / 520 pitch — fits OEM 520-chain applications and suitable 520 conversion setups

The Vortex CAT5 sprocket series is available in multiple colors (in most sizes), each featuring contrasting silver machine cuts for a distinctive race-inspired look. This sprocket is an ideal upgrade for sport bike riders seeking a high-quality, American-made alternative to stock rear sprockets.
