Vortex 427AZR-42 Aluminum Rear Sprocket 42 Tooth

The Vortex 427AZR-42 is a high-performance aluminum rear sprocket designed for sport and racing motorcycles. Precision-machined from lightweight 7075-T6 aluminum alloy, this sprocket delivers exceptional strength while reducing rotational mass for improved acceleration and handling response.

Key Features:

• 42-tooth configuration for optimized gearing
• 7075-T6 aluminum construction for superior strength-to-weight ratio
• CNC-machined for precise tooth profile and chain engagement
• Hard-anodized finish for enhanced durability and wear resistance
• CAD-designed tooth profile reduces friction and extends chain life
• Self-cleaning mud grooves prevent debris buildup
• Manufactured to strict OEM tolerances for perfect fitment

Vortex sprockets are engineered to meet the demands of professional racers and performance enthusiasts. The aluminum construction significantly reduces unsprung weight compared to steel sprockets, improving suspension performance and overall bike handling. The hard-anodized surface treatment provides excellent wear resistance while maintaining the weight advantage of aluminum.
