Vortex V4A Aluminum Rear Sprocket Sprockets - V4

The Vortex V4A is a next-generation aluminum rear sprocket from Vortex Racing, representing the evolution of their legendary CAT5 platform. Built on decades of experience supplying drivetrain components to professional racing teams and performance riders worldwide, the V4 design delivers a 10–15% reduction in weight over the CAT5 without sacrificing structural integrity.

Key Features:

• Next-generation V4 sprocket design with optimized material removal pattern
• 10–15% lighter than the classic Vortex CAT5 sprocket
• 100% CNC manufactured in the USA
• Specially formulated aluminum alloy per Vortex specifications
• Machined faces on both sides for a premium two-tone appearance
• Anodized finish helps prevent corrosion and oxidation
• Unique tooth profile engineered for extended sprocket longevity
• Vortex patented sprocket design

The V4A is ideal for road racing, track days, and high-performance street applications where minimizing rotational mass is critical. Vortex aluminum sprockets reduce rotating weight to improve throttle response and maximize rear-wheel power output. As with all aluminum sprockets, proper chain maintenance every 300–400 miles is recommended to maximize service life.
