About the windscreen, I am 6'0" with an inseam of 32"s --- this VStream is perfect for me. In the full up position it provides a quiet ride and yet seeing over not thru, also with NO negative back pressure. My old ST1300 created back pressure, something that I always felt. VStream's R&D in my opinion was spot on for this ride.
The Canyon Cage by MC Enterprises was recommended by the dealership during purchase. I finally gave in later on and installed a set purchased online from manufacturer. Beautiful assembly --- welds, chrome and hardware are all topnotch.
The GIVI 47L Top Trunk with color coordinated lid. Will almost fit 2 full size helmets --- no lights on this trunk.
