My bike came with a 15 in. windspliter, hated it. Began looking for a new shield and ended up ordering a windvest 10 in. gunsmoke as the fitment chart suggested, too short and dark. Sent it back and got the 13 in. in light tint. PERFECT! The wind stream just catches the top of my helmet and my eyes are 2-3 in. above the top. At 5' 10" on a sundowner seat ( adds 1 in. over stock) and on a air hawk ( adds another half in.) it's going to work great. I wish Windvest would list the height of each shield from the top vent to the top of the shield, better fitment method in my opinion. FYI, the 13 in. is 6" above the vent to top of shield.
