My riding buddy just upgraded to a very nice 03 1800 (which I found for him) We took turns riding it home, and what a differance in power over the 1500. At 6' 2" the 1500 still seems to fit me better and I had a strange experience riding this 1800. It does have a shorter windshield and at speeds above 55mph. I get a pronounced side to side flutter with my head. This was enough to slightly blur traffic in front of me, and caused a headeache. In putting a hand around the front, top, sides, and back of helmet, the only place any real wind found was just across the top, but even there it did not seem turbulant. I found if I crouched down slightly, the buzz went away. I assume I would have to have stock height or taller windshield and wonder if that would just transfer this problem to passenger? My buddy loves this bike over his 1500 due to handling, power, and how light it feels compared to the 1500, and he does not get any of the flutter that I do. Any comments or ideas would be appreciated. I would love to upgrade myself if I knew I could get it set up comfortably for my size. (I am on my 4th seat on my 1500 to get it right for me, which is lowboy road sofa with gel pacs- seat ergonomics are perfect for sitting in instead of on the bike.) Will get pictures of current ride posted soon!
