Vortex 316BZR-43 Aluminum Rear Sprocket 520 Pitch 43 Tooth

The Vortex 316BZR-43 is a high-performance aluminum rear sprocket designed for 520 pitch chain applications. This 43-tooth sprocket features precision CNC-machined construction from lightweight 7075-T6 aluminum alloy, offering an excellent balance of strength and weight reduction compared to steel sprockets.

Key Features:

• 43-tooth configuration for customized gearing ratios
• 520 pitch chain compatibility
• CNC-machined from 7075-T6 aerospace-grade aluminum
• Blue zinc-plated steel center for enhanced durability
• Self-cleaning mud groove design prevents debris buildup
• Lightening holes reduce rotational mass for improved acceleration
• Precision tooth profile extends chain life
• Anodized finish for corrosion resistance

Vortex sprockets are manufactured to strict tolerances and undergo rigorous quality control testing. The aluminum construction significantly reduces unsprung weight while the hardened steel center insert ensures long-lasting durability in the mounting area. This sprocket is an excellent choice for racers and street riders looking to optimize their motorcycle's performance through gearing changes.
