Dont have any vibration on my new model to speak of. if it is new, I´d ask the dealer to check and also ride another one for acomparison. On the screen, I did fit the yami raised screen which is an improvements on the standard screen as you would expect. I find you still have to hang on hard over 90-100 (where permitted, of course). I think Raptors and Rocklets may have a slightly higher one, which also has an extra deflector on the top edge.
