All IMO: The easiest to convert would be one of the dual-purpose thumpers in the 400cc-650cc range. Already street legal, you'd only *need* to focus on the wheels, tires, and suspension. Of course, there would be lots of other "little" things you could do (bars, pipe, seat, etc.). Next up would be a Yamaha YZF400/426 or WR400/426 (which is where my current focus is). It's tempting to try to convert an open-class two-stroke like the CR500 or KX500, but, besides the problems with making them street legal, they are beastly. A thumper just makes more sense, and will be easier to live with.
A few of my buddies have run into these guys, in Ottawa, that had 'tarded up some CR 500's and put them on the street. They said, around here, it's pretty easy to go through the loopholes and license a dirt bike for the street. Of course a big thumper would be more reliable, (and less conspicous), but IMO a CR or KX would be more of a hoot.(nasty, noisy, smoky, etc.,etc...) I've never had the sh!T scared out of me more consistently, then when riding CR 500's, especially in tight, confined, tree lined, trails.
