I'm new here and not so familiar with the prices of bikes, or where all to look for bikes. So far I've been looking at trademe. I haven't found much for sohc4 bikes either. I did find one today that I was wanting your expert opinions on. The reg is dead and from what I've read it'll take a bit of a head ache and around $450 dollars to re-reg. I'd also have to rent a truck or trailer to go get it. Anyway, here's the bike.
