I took my hands off the bars of my 07 Fatboy to change glasses at about 25mph and I was surprised to see a wobble and I put my hands back on immediately. I found a quiet street and performed some experiments, and even got my girlfriend on the back to shoot videos (ok maybe not the smartest thing). When I took my hands off, it started to wobble and with eachiteration it grew more violent - I let it go about 2" back and forth before I stopped it. I was holding my hands about 1" away from the bars, so I could grab it quicky. I googled this, cause I was really surprised as I saw lots of harleys coming to a light, and the rider would put a cigarette in his mouth and light it, taking both hands off for a little while. While googling it (you can google yourself) I found a lot of incidences, and several deaths. The most publicized seemed to be an auto dealership owner, who got a wobble at 55mph and died - with lots of witnesses. they called it a "tank slapper". I read the biggest issues with wobbles were 1) Loose Spokes, and 2) inproperly inflated tires 3) deceleration induced wobble. I don't have spokes on my bike, I have the solid wheel, and I checked the pressure and it was fine, and I tried letting go in neutral also. I have a friend thats an ex-harley mechanic, and I emailed him the videos and he said to take it to the dealer immediatey. I called the dealer, and first he said thats normal, all his rental heritages wobble if you take your hands off, and he told me that I'm not supposed to take my hands off. I told him I don't have spokes and it shouldn't wobble, and he told me to not to ride it anymore and they will send a truck to pick it up and they did. While it was in, they took everything apart, I could tell because the wiring, cabling and bars was different, and put it back together. The dealer told me that they didn't find any problem. They also told me that they took everything apart, and retightened it to specs, so they don't know if something was out of spec or not. It took me a day or two to get up enough courage, to try it and I performed a bunch of tests, and even increased the speeds to 45mph, but there isn't any wobble at all any more. My guess is that there was something loose in the front end, or an out of balance tire.

Oh, I read about other bikewobbles, its not just Harley, and it is a good idea to always keep your hands on the bars.
