My vespa px200 vibrates almost from the glovebox when front breaking heavily or at speed.......any suggestions ? Thanks in advance

Check your steering bearings are under correct tension.

Check your front wheel for any play.

then check if your front disk is warped if you spin your front wheel with your hand you will be able to see it if you look directly at the disk . it might only be a slight warp but under heavy breaking would re act quite bad .to check stearing you need some one sat on the scoot and someone at the front grab both bars and pull them backwards and forwards you will feel if the bearings have play in them . if you feel nothing pulling and pushing against the bars you can rule out the bearings.to check the front wheel bearings make sure the front wheel is off the ground and rock the wheel from side to side you will feel it move and probably see it if the bearings are on there way out

Can you feel it through the handlebars, or just hear it banging?
