Vortex CK7500 HFRA Chain and Sprocket Kit - V3 2.0 520 Black

The Vortex CK7500 is a V3 2.0 HFRA (Hyper Fast Racing Aluminum) 520-pitch chain and sprocket kit designed for high-performance motorcycle applications. This complete drivetrain kit includes a chromoly-steel front countershaft sprocket, a precision aluminum rear sprocket, and a 520 RX3 X-ring chain — everything needed for a full chain drive replacement in a single package.

The kit is built around Vortex's F5 PTFE Black Hardcoat treatment on the aluminum rear sprocket: a process that begins with hard anodizing and a jet-black dye, followed by a PTFE coating for added lubricity. The result is an extremely durable, lightweight sprocket that resists contamination and reduces friction over its service life.

Kit Contents:

• Front sprocket: Vortex 3258 — 16-tooth, 520-pitch, chromoly steel
• Rear sprocket: Vortex 193AK — 47-tooth, 520-pitch, F5 PTFE black hardcoat aluminum
• Chain: Vortex 520RX3-118 — 118-link, X-ring, black

Key Features:

• Aerospace-grade aluminum rear sprocket for reduced rotational mass and optimal power transfer
• X-ring chain design withstands high tensile loads for reliability under extreme conditions
• F5 PTFE black hardcoat finish for enhanced durability, lubricity, and a cleaner-running sprocket
• Precisely manufactured to tight tolerances for concentricity and smooth power delivery
• Allows fine-tuning of gear ratios for improved acceleration and top-end performance
• Drop-in OEM replacement or performance upgrade — no cutting or modification required

The Vortex CK7500 is an excellent choice for riders looking to replace worn OEM drivetrain components with race-proven hardware, or those seeking improved performance through lighter rotating mass and a more aggressive gear ratio.
