OK, well now I'm just plain curious. Since I bought this beast, I've mostly been on twisty roads around the lakes east of Phoenix, but as soon as it gets below 110 degrees around here, I'm gonna go play on the freeway and look for trucks. I'm coming off of a Kawi Concours, which is no lightweight, and has plenty of wind protection, and would heel over like a 12 meter racer in a strong cross wind. Dirty air, though - nothing. Passing, getting passed or following trucks was completely unnoticeable, one-up or two-up. Come to think of it, I did log a fair number of freeway miles on the day I rode the GTL home from the dealer, and I remember being behind or beside at least a couple of trucks as I was doing lots of shifting and varying engine speed. I don't remember noticing any additional puckering from the aerodynamics. Maybe I just have steely nerves and superhuman reflexes - no, I've seen the videos - that's not it. I'm definitely gonna go play on the freeway, though.
