Vortex 625ZK-54 Steel Rear Sprocket Pitch Sprockets - 525 54-Tooth

The Vortex 625ZK-54 is a 54-tooth steel rear sprocket designed for 525-pitch chain applications. Built to the exacting standards Vortex Racing is known for, this sprocket is precision-machined and induction-hardened to deliver a stronger, more concentric fit than standard OEM replacements.

Key Features:

• 54-Tooth / 525 Pitch — direct replacement or gearing upgrade for compatible motorcycles running 525-pitch chain
• Induction-hardened steel construction — the controlled induction hardening process creates extremely tight tolerances and a harder tooth surface for extended wear life
• Precision CNC manufactured — 100% CNC machined in the U.S.A. for consistent concentricity and quiet operation
• Zinc-coated satin finish — electro-plated finish resists corrosion and adds a clean, polished appearance
• Hardened teeth — tooth hardness ensures the sprocket maintains strength through high-mileage use
• Vortex ZK bolt pattern — engineered to match the specific carrier bolt pattern of compatible sport and naked bike platforms

Vortex Racing steel rear sprockets offer the ideal balance of weight, strength, and durability for street and track riders who want a direct OEM-style replacement with upgraded performance. The 625ZK-54 is a reliable choice for riders looking to fine-tune their final drive ratio or simply replace a worn sprocket with a proven, high-quality component.
