Yeah, I've got an '06 C50 and the vibration is killing me. I know that bikes shake a bit but this is ridiculous. I take this 200 mile trip about once a month and after about two hours of it you start to hurt. I'm not meaning to whine but dang. I pulled the clutch in going down a steep hill and it was as smooth as silk. that's what riding should feel like right? as soon as i rev up the engine, even sitting still, the whole thing shakes terribly. i'll try out the exhaust stuff you guys have mentioned and maybe upgrade to knew stuff. sounds like it's just a simple mistake or something.
