Sure, because there are a ton of older bikes on the road. Even the motorcycle tested in the article was from 2004; there have been two newer emissions standards released since then. (The newest standard is required this year in CA, and by 2010 in the rest of the US.)
Besides, figure in the extra costs and pollution involved in producing the extra fuel for the Durango (Durango is 14/19 mpg), manufacturing the extra 4,200 pounds of hulk in carries around, disposal of the extra oil it carries to each oil change, road repairs, etc., and I think you'll find that a modern motorcycle or scoot is pretty competitive.
