for the members that remember those bikes, may be interested in the web site i made for our club, our club caters for bikes built before 65 to pre 85 here in Australia , we only do natural terain and never the same track twice. My son does vintage with us now. My oldest bike is a yamaha mx 250b a evil handling bike that goes like crazy cant stop and wont turn but anyone who rides it gets a huge grin from ear to ear.
