It opens fully and can be ran open with no issues.. I get 65mph on the black top regularly with mine. I probably wouldn’t trailer with it up though.
The fit at the hood is fine but the roof has some to be desired. It’s just straight across 5-6 inches from the roof. I cut a piece of alumabond (use plexiglass, Lexon or whatever you have laying around) that fit the gap and contoured to the roof and put a piece of pipe foam as a roof gasket on it. I used a channel gasket (same as goes against the hood) on the bottom side and that seals against the top lip of the windshield. It now seals against the gasket and does a fine job keeping water and rain from coming over top. I’ve posted pics on here a couple times. I’ll see if I can find them. If not I’ll take some more.
As for it being worth it.. I bought mine on sale for 325-350 ish.. is it worth getting? If you’re always hot, then yes! If you want to shoot out the front of the machine it’s great!
Sell the Honda for 200-300 and you’ll be happy!
Oh, and if I were you I’d trace the top of the Honda windshield profile when I took it off. It will make life much easier.
