The Vortex 526ZKV4-43 is a 43-tooth, 525-pitch aluminum rear drive sprocket finished in black anodize, engineered for street and track motorcycle applications. CNC-machined in the USA from a specially formulated aluminum alloy to Vortex's exacting tolerances, it delivers a precision-fit, perfectly concentric sprocket seat and smooth, consistent power transfer.

Key Features:

• 7075 T6 billet aluminum construction — aerospace-grade material for maximum strength at minimal weight
• 100% CNC machined in the USA — tight tolerances ensure a precisely concentric fit and smooth chain engagement
• Black anodized finish — corrosion-resistant coating bonds to the aluminum surface for added durability and a clean appearance
• 43 teeth / 525 chain pitch — direct-fit replacement or performance upgrade for compatible 525-chain equipped motorcycles
• Unique Vortex tooth profile — patented design reduces chain drag and extends the service life of both sprocket and chain
• Reduced rotating mass — lighter than OEM steel sprockets for improved throttle response and quicker acceleration
• Built-in mud/debris grooves — helps clear contaminants from between teeth to maintain drivetrain efficiency
