Sorry I did not see your message till now. The windshield comes off easily, just 6 knobs and it is off. The brackets will stay in place. The vent will probably be in the way for kids. You should consider one of the folding windshields if that is a concern.
Quick ? for you, how easy is it to take off your windshield? Really want one for cold weather riding but want to be able to easily take it off once the weather gets hot. Also, how high is the vent? I'm assuming it will be right in my 2 small kids line of sight since they can barely see over the dashboard now.
