Vortex 825ZLV4-42 Aluminum Rear Sprocket 530 Pitch 42-Tooth Silver

The Vortex 825ZLV4-42 is a 530-pitch, 42-tooth aluminum rear sprocket engineered for performance motorcycle applications. Designed as a direct lightweight replacement for heavy OEM steel sprockets, this sprocket reduces rotating mass to improve throttle response, acceleration, and overall drivetrain efficiency.

Key Features:

• 7075 T6 billet aluminum construction — aerospace-grade alloy delivers an exceptional strength-to-weight ratio
• 100% CNC machined in the USA — precision tolerances ensure consistent chain engagement and smooth power transfer
• Silver anodized finish — protects against corrosion while providing a clean, race-inspired appearance
• 530 chain pitch — compatible with standard 530-pitch motorcycle drive chains
• 42-tooth rear sprocket — stock-equivalent gearing for balanced acceleration and top-speed performance
• Unique Vortex tooth profile — patented design promotes extended sprocket longevity and consistent chain wear
• Significantly lighter than OEM steel sprockets, reducing unsprung and rotating weight
