Vortex CK6255 Chain and Sprocket Kit Conversion with Hardcoat Aluminum Rear Sprocket - 520

The Vortex CK6255 is a complete, ready-to-install chain and sprocket kit featuring a 520 conversion with a one-tooth-down front sprocket change for improved acceleration. No chain cutting is required — everything needed for a straightforward installation is included in the kit.

The kit includes a Vortex SV3 Series 520RV3 chain, manufactured in Japan to exacting quality standards. The SV3 chain utilizes a dual pocket sealing system that delivers up to 7 times longer wear life compared to standard O-ring chains, making it an exceptional upgrade for both street and performance riding.
