when does it vibrate? meaning at what sort of speed? i would suggest checking the bearings for any play or possible sticking, if theres no play then a good greasing may help, i had a mk2 that did it when i tested it down a private lane ( as it was road legal) but it only did it towards the top speed but i found very little play in the bearings, i did replace them and grease the spindle but never used it on road only off so i cant tell you how much difference that made

Check bearings as John says.

Also -

Check tyre is correctly seated on rim.

Check for buckling of the rim.

Some heavy rim locks cause 'hammering' when travelling at speed.

Check headstock bearings for play.

yep headstock bearings are a known culprit too, had that on an mtx 125
