Why is it, that under hard accelleration, when your front wheel is trying to come up, and barely on the road, sometimes the whole front end starts to shake pretty violently?

Because the wheel is skimming on top of the road. There's not enough traction.

Like Nauree said. There's not enough traction and weight on the wheel to keep it stable, but there is just enough traction to move it around a little.

thats where a steering damper comes in. the more you try to hold it steady, the worse it will get. the front end will naturally oscillate and come back in
line by itself. its physics- if you try and fight it, your going down.

when you feel it getting light, you need to have no pressure on the bars, you should be holding yourself up with your torso muscles, it will settle in. If you try and bring it undercontrol by holding the bars, your arms will actually transfer the headshake to the rest of bike and make it much worse.

Yeah, I've already realized that fighting it only makes things worse. I just ease up slightly on the the throttle and let it do what it do.

Just thought i'd ask why it did that, to learn a little bit more about the physics of my bike. Thanks everyone.
