When i got my $150 300ex the quad came with a few 250 parts like the front fenders and the gas tank. i have no idea what he did with the 300s, but this is all i have at the moment and i have not checked, but for some reasons everthing for the 300 is so expensive compared to the 250 and 400. will anything from the 250 work? if not is there anything else that has plastics or gas tanks that fit, because a used price for the 300exs gas tank is almost 200 when the 400s is about 30-40.
