You should establish some serious timelines when dealing with vintage/antique/classic collectables. North American motorcyle groups look at classic as being 25 years...British groups are much less tolerant of modern machinery and won't include machines that young. This gives their groups focus, direction and credibility. I think it's very important to maintain a very strict time frame, with certain exceptions being tolerated. For example, it's not unworthy of the list to mention modern repro classic bikes when there is a context to do so. As long as things don't devolve into previews on the 2003 lineup of lugged steel bikes. I do think that the" for sale" criteria should be strictly adhered to. There is already a huge volume of stuff for sale out there.
Dale will have to be the judge and jury...which seems to be just fine with a majority of the list.
