126 link, #25 chain is compatible with the Razor MX350, MX400, and RSF350.

This chain consists of 126 links (126 pins) and measures 1/4" wide. It is a #25 size chain. The link count of 126 includes both inner and outer links, but is sometimes referred to as a 63 link chain if only counting the outer links. If in doubt, count the number of pins needed as this chain includes 126 pins that link together 63 outer links and 63 inner links (126 total).
