I'm far from a Harley guy (hate 'em, actually), but isn't the term hog strictly a Harley term? I don't ride anymore, but my last bike was a Kawasaki Ninja, ZX-7R in Kawa Green. Pretty well modded, with a polished-to-chrome frame, subframe, and swingarm. I don't have any pics handy.
You got me? I'm a relatively new rider (1 year). My friend has a Harley, but when I showed him my 150cc scooter I had last year, he said "Nice Hog". No offense to Harley enthusiasts. Lord know there are plenty of 'em here in the Harley Homeland.
