Where do you live Young Pup? Its not Simon is it, who races with us at Fairbairn Park (and who's a mere stripling at 32)? I know he just got hold of two '83 CR250s (I thought) to do up and race with us in the old buggers class (ok, old bikes class). If so, up and at them mate, we look forward to you putting it to us.
I race an '83 CR250 at Fairbairn and elsewhere, and can guarantee that they are a good all round mx bike. Good power, good handling (despite what ADB said about them in the day), very reliable. Parts cost, but you're worth it aren't you?
