Vortex 615-46 Silver Aluminum 46-Tooth 520-Pitch Rear Sprocket

The Vortex 615-46 is a high-performance aluminum rear sprocket designed for motorcycles using 520-pitch chain. Made from aerospace-grade aluminum, this 46-tooth sprocket delivers significant weight savings compared to steel alternatives while maintaining excellent durability for racing and performance applications.

Key Features:

• 46-tooth configuration for precise gearing control
• 520 pitch compatible with standard 520 chains
• CNC-machined from 7075-T6 aluminum alloy
• Silver finish with clear coating to help prevent oxidation
• Unique tooth design increases sprocket longevity
• Two-tone machined appearance for distinctive look
• Lightweight construction reduces rotational mass for improved throttle response

Aluminum sprockets are very sensitive to chain cleanliness and tension, so bikes with aluminum sprockets should have the chain cleaned and tensioned every 300-400 miles. This sprocket is ideal for road racing, track days, and performance street applications where weight savings is a priority. The Vortex CAT5 design pattern provides optimal strength-to-weight ratio while the precision machining ensures smooth, consistent power transfer.
