As far as the budget goes, from what I've seen on ebay at least, a race ready 125 or 250 could go for between 2 and 4k depending on how nice it is or whether it's a sought after model. He's cool with that sort of price range.
Brad, is that the one that was on ebay a little while ago?, I thought it had sold?
BigK, I know he looked at an RM400 and liked it, but wasn't sure if a big bore two stroke might be a big jump to make after riding 4 stroke KTM's for the last 10 years. The shipping would be another factor I suppose.
I'll let him know what's out there and get back to you.
Thanks guys
