The Vortex 150ZK-48 is a 520 pitch, 48-tooth steel rear sprocket finished in an electro-plated satin black coating. Built for Kawasaki applications, it is machined to precise tolerances to ensure true concentricity and smooth chain engagement throughout its service life.

Key Features:

• Material: Carbon steel construction for exceptional strength and wear resistance
• Finish: Electro-plated satin black finish resists corrosion and road grime
• Chain Pitch: 520 pitch — compatible with standard 520 chain systems
• Tooth Count: 48 teeth
• Design: Cupped-down face profile reduces overall weight without sacrificing structural integrity
• Hardened Teeth: Heat-treated tooth profile for extended sprocket and chain life
• Fitment: Kawasaki-specific bolt pattern

Vortex steel rear sprockets are a popular choice for riders who prioritize durability and longevity over the weight savings of aluminum — ideal for street, touring, and off-road applications where reliability is paramount. The 150ZK-48 is a direct OEM-style replacement or gearing upgrade option for compatible Kawasaki motorcycles.
