First post, hello TT! I bought a full-of-character 2004 DRZ 400 in the SF Bay Area recently. Whenever I cross the Bay Bridge I stuff some coal up my rear and spit out a diamond on the other side; it's pretty much white knuckles going 40+ mph. This from a 6' 170 lb guy. Around 40 ish I get rocked around by the wind pretty easily. I can feel the effects of the road grading more. The bike isn't weaving; I just feeling everything. I noticed some very slight front end oscillating if I'm going 50+. Also it seems more pronounced the longer I'm on the bridge. I saw some posts stating any tight grips on the handle bar makes the ride less smooth. So I ease up whenever I notice this. But that doesn't seem to be the reason for the initial rockiness. While the bridge gets some strong cross winds and the grading isn't perfect, should I expect white knuckles whenever I get about 40 ish? I still have the stock knobbies on the front and back. Air is slightly above rating when cold. I haven't looked into anything else like suspension. Would I get a smoother ride with a street tire in the front? Cheers!
