There is no better windshield than the Givi one for the 400 Burgman. It covers the whole body and hands with the flaps it has. Ideal for trips, it doesn't tire at all and you forget about the wind even on long distances. After 5 years of use, it is still like new with excellent visibility. The only drawback is the rain, where if you fall into a lot of water you can't see, but this is necessarily a problem with all tall windshields. Put it on with your eyes closed and don't skimp on others for 20 or 30€ less.
