The Vortex 775AZLV4-42 is a 42-tooth aluminum rear sprocket designed for performance motorcycle applications. Engineered as a direct OEM replacement or upgrade, this sprocket delivers a significant weight reduction over stock steel sprockets, reducing rotating mass for improved throttle response and overall drivetrain efficiency.

Key Features:

• 7075-T6 billet aluminum construction — aerospace-grade alloy for an optimal strength-to-weight ratio
• 42-tooth rear sprocket — maintains stock gearing or serves as a direct replacement
• Anodized finish — provides a durable, corrosion-resistant surface that bonds to the aluminum for extended service life
• 100% CNC-machined — manufactured in the USA to tight tolerances for precise chain engagement
• Lightweight design — reduced rotating mass improves acceleration, deceleration, and directional response
• Compatible with standard sprocket bolt patterns for the 775 carrier series
