Vortex CK6147 Chain and Sprocket Kit Gearing - 520RV3 16/45

The Vortex CK6147 is a complete chain and sprocket kit engineered for performance riders seeking a reliable, ready-to-install drivetrain upgrade. This kit comes pre-sized and requires no chain cutting, making installation straightforward and hassle-free.

At the heart of this kit is the Vortex 520RV3 Series chain, manufactured in Japan to the highest quality specifications in the industry. The SV3 Series chain features a dual pocket sealing system that delivers up to 7 times longer wear life compared to standard O-ring chains, making it an exceptional value for performance and longevity.

Kit Specifications:

• Chain: 520RV3 — 116 links
• Chain Origin: Made in Japan
• Chain Type: SV3 Series with dual pocket seal technology
• Master Link: Rivet-type included (clip-type links available separately)
• Rear Sprocket: Laser-cut steel construction
• OE Gearing: 17/45 (front/rear)
• Kit Gearing: 16/45 — one tooth down on the front sprocket for improved low-end acceleration

The 16/45 gearing configuration drops one tooth on the front sprocket compared to OEM, providing quicker throttle response and improved acceleration out of corners. This makes the Vortex CK6147 an ideal choice for riders looking to sharpen performance without changing the rear sprocket ratio.

All components in this kit are designed to work together as a matched set, ensuring optimal chain-to-sprocket engagement and extended service life across all drivetrain components.
