I´m taking delivery of my new Burgman 400 ABS in April, this year. I had a Vespa 200 GT for two years prior to this. I found that I do a lot of 400 highway series riding & the Vespa was not quite powerful enough to comfortably handle that type of riding.I´m planning on replacing the windshield for a Givi which is larger. I´ll probably have to cut the height down a little. Any comments or advice?
