Vortex 438ZBV4-47 VTX Aluminum Rear Sprocket 47T 530-Pitch Blue

The Vortex 438ZBV4-47 is a lightweight VTX-series aluminum rear sprocket designed for performance motorcycle applications. Featuring a 530-pitch chain compatibility and a 47-tooth count, this sprocket allows riders to fine-tune their gear ratio for improved low-end acceleration or optimized top-end performance. The striking blue anodized finish is applied before the sprocket is CNC-machined, resulting in Vortex's signature two-tone appearance where the machined aluminum contrasts against the anodized color.

Key Features:

• 47 teeth on a 530-pitch rear sprocket for precise gearing adjustments
• Blue anodized finish applied pre-cut for a distinctive two-tone machined look
• Lightweight CAT5 aerospace-grade aluminum construction — approximately half the weight of a steel equivalent
• 100% CNC manufactured in the USA to exacting tolerances
• Specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• Patented saber-tooth groove design promotes longer sprocket life and reduces wear
• Anodized coating resists oxidation and corrosion

Aluminum sprockets like the 438ZBV4-47 are the preferred choice for road racing, track days, and high-performance street riding where reducing rotational mass translates directly to faster throttle response and improved rear-wheel power delivery. To maximize service life, chain cleaning and tension should be checked regularly — Vortex recommends every 300–400 miles for bikes equipped with aluminum sprockets. Must be used with a 530-pitch chain and compatible front sprocket.
