So, I'm out riding, trying to practice wheelies. I finally give up on wheelies, because I can't find a good place to do them, and decide to jump on the highway. I get on the Washington Beltway (I-495), and nail the throttle. I have the throttle nailed, and I'm cutting across from the merge lane to the far left lane, when I hit 3rd gear, and suddenly my handle bars are doing some serious shaking. I think I hit some bumps at the same time I let the clutch out, and it brought the front wheel up just a bit. I look at the speedo, and it reads 105, and for a second, I thought I might be finished. Everything happens so fast at that speed, you only have seconds to react. The bars probably only shook like that for about 5 seconds, but it seemed like forever. I let off the gas, and brought the front wheel down, but it definetely scared the shit out of me. Might be time for a steering damper. I thought it was ironic, that I couldn't get a wheelie going when I was trying, and then I got one when I didn't want one. Oh well, live and learn.
