Vortex 525CZB-45 Black 45-Tooth 525-Pitch Steel Rear Sprocket

The Vortex 525CZB-45 is a 45-tooth, 525-pitch black steel rear sprocket engineered for street and performance motorcycle applications. Built by Vortex Racing — a U.S.-based manufacturer with a long track record in Motocross, Supercross, Road Racing, and Flat Track — this sprocket delivers the durability and precision demanded by serious riders.

Constructed from high-quality carbon steel and finished with an electroplated satin black coating, this sprocket is built to resist corrosion and withstand heavy use. The teeth are case-hardened for extended wear life, and the sprocket body is laser-cut to tight tolerances for accurate chain engagement and smooth power delivery. The cupped-down body design reduces weight without sacrificing structural integrity.

Key Features:

• 525 chain pitch — compatible with 525-pitch drive chains
• 45 teeth — provides strong rear-wheel torque and acceleration characteristics

• Electroplated satin black finish — resists corrosion for long service life

The Vortex 525CZB-45 is an excellent choice for riders looking to maintain OEM-equivalent strength with a clean black aesthetic, or for those replacing a worn sprocket as part of a full chain and sprocket service.
