Do you just have a mile commute? Or do you really want to release your inner hooligan? I've seen some really cool small cc cafe's. I got blasted by one Saturday. I was doing about 50 in a 45mph zone when one shot by me. Full out Hi-Po CB (maybe 200cc) sporting an antique plate.
We've got a group here that only builds small bore vintage Jap bikes. They usually ride in groups of 5 or so. You hear something that sounds like a swarm of bees, look up in your mirror and see nothing but a Rising Sun helmet w/goggles. The anti-bobber look.
