Is this chain the same as a bike chain but wider.small sprocket 2 1/2 in. across with 12 teeth ,large sprocket is 6 in. with36 teeth ? total chain length 25 inches. 1 inch pin to pin on each link.

if it's 420, alot of the smaller motorcycles use that , 50cc - 80 cc. should be easy to find what you need.

none of the bike shops around here had it. and we don't have gokart shops anymore.. they WOULD have had it.

I ordered it from northern.
