Down here in El Paso, I'd have to say that my numbers pretty line up with your own. It's mainly cruisers & crotch rockets around here though. I've only seen two dual-sports in the last three months, and they were both beemers, so I can't speak to the KLR numbers. I did have two Harley riders wave on my way back from Lowe's about an hour ago though. That always surprises me.
I saw a couple of KLRs last weekend between Gallup, NM & Sedona, AZ, both were of them looked liked they had been ridden hard & put away wet. I was cage-bound (purpose of the trip was to keep me in the good graces of the spousal unit), so I can't say whether they would have waved or not.
Interesting phenomenon, though... I wonder what others have been seeing?
