Vortex CK6223 520 Chain and Sprocket Kit with Quick-Acceleration Gearing

The Vortex CK6223 is a complete 520 chain and sprocket kit engineered for enhanced acceleration and reduced rotating mass. This kit includes a steel front sprocket, a hardcoat anodized aluminum rear sprocket, and a Vortex SV3 series 520 chain — everything needed for a direct bolt-on installation with no chain cutting required.

This kit features a quick-acceleration gear ratio of 14/47, compared to the OEM gearing of 15/47 (one tooth down on the front sprocket, stock rear). The reduced front sprocket tooth count sharpens throttle response and improves low-end acceleration.

Key Features:

• 520SV3 Chain — 108 Links: Made in Japan to exacting quality standards, the SV3 series chain features a dual pocket sealing system delivering up to 7 times longer wear life compared to standard O-ring chains
• Hardcoat Aluminum Rear Sprocket: F5 aerospace-grade aluminum with black hard-coat anodizing for exceptional durability and reduced rotational mass
• Induction-Hardened Steel Front Sprocket: Precision-machined chromoly steel for reliable power transfer and long service life
• No Chain Cutting Required: Each kit is pre-sized to the correct length for a straightforward installation
• Rivet-Type Master Link Included: Clip-type master links are also available separately
• Quick-Acceleration Gearing: Kit gearing 14/47 vs. OEM 15/47 for improved low-end pull and faster acceleration

Vortex chain and sprocket kits are a popular upgrade for riders looking to improve drive train performance, reduce weight, and fine-tune their gear ratio without the complexity of a full 520 conversion. The SV3 chain's advanced dual-pocket seal design minimizes friction and heat buildup, extending service intervals and overall drivetrain longevity.
