so you DO require a specific "TYPE" of bike, just not a particular "BRAND" of bike... You want bikes that look like they were the pinnacle of engineering in 1937, not bikes that are designed to perform and compete, or that have had a major design upgrade, you know in say the past 60 years... You've stated that you discriminate based on arbitrary engine displacement volume, regardless of power output... Do you also discriminate against dual sports, standards, streetfighters, sumos and long tourers? Or is it just things that look like sport bikes?
