The Vortex 765ZB-45 is a 45-tooth rear sprocket machined from high-strength 7075-T6 aluminum alloy and finished with a hard black anodize coating for enhanced durability and corrosion resistance. Designed as a direct OEM replacement or performance upgrade, this sprocket delivers precise chain engagement and consistent power transfer for street and track riding.

Key Features:

  • 45-tooth rear sprocket for optimized acceleration and throttle response
  • 7075-T6 aluminum construction — lightweight yet highly durable

Delivery was incredibly quick; it goes out the door very fast, which I appreciated when needing something for my boat.
