Vortex 526AZK-48 CAT5 Aluminum Rear Sprocket 48-Tooth 520-Pitch Black

The Vortex 526AZK-48 is a 48-tooth, 520-pitch CAT5 aluminum rear sprocket designed for performance-minded motorcycle riders seeking a lightweight, race-proven drivetrain upgrade. Manufactured 100% in the USA via CNC machining, this sprocket is built to exacting tolerances from a specially formulated aluminum alloy developed exclusively to Vortex's specifications.

Key Features:

• CAT5 aluminum construction — specially formulated alloy for maximum strength-to-weight ratio
• 100% CNC manufactured in the USA for precise concentricity and consistent quality
• Patented Vortex tooth design engineered to extend sprocket longevity and improve chain engagement
• Black anodized finish with contrasting silver machine cuts for a premium appearance
• Lightweight design reduces rotating mass for improved throttle response and drivetrain efficiency
• 520-pitch — ideal for OEM 520 applications or as part of a 520 conversion kit
• Available in 4 colors to suit a variety of bike aesthetics

The 526AZK-48 is a popular choice for riders performing a 520 chain conversion, allowing significant weight savings over larger-pitch OEM drivetrain setups. When converting pitch, the front sprocket, rear sprocket, and chain must all match the same pitch. Vortex's aluminum sprockets are approximately half the weight of comparable steel sprockets, making them a preferred upgrade for street performance, track days, and racing applications.
