Vortex 525AZB-43 Aluminum Rear Sprocket 43-Tooth 525 Pitch Black Anodized

The Vortex 525AZB-43 is a 43-tooth, 525-pitch aluminum rear sprocket finished in a durable black anodized coating. Designed and manufactured in the USA by Vortex Racing, this sprocket is precision CNC-machined from lightweight 7075 T6 billet aluminum to exacting tolerances, delivering a measurable reduction in drivetrain rotating mass compared to stock steel sprockets.

Vortex's patented tooth geometry is engineered for optimized chain engagement and release, extending both sprocket and chain service life. The black anodized finish is applied before final machining, producing the brand's signature two-tone look while providing corrosion resistance.

Key Features:

• 43-tooth / 525 pitch — direct OEM-pitch replacement for bikes equipped with 525 chain
• 7075 T6 aerospace-grade aluminum — lightweight construction reduces rotating mass and improves throttle response
• Black anodized finish — corrosion-resistant coating with aggressive black styling
