Here's my opinion on a few things, take it or leave it. Just thought I'd try to help.
Half windshield - I bought the Honda half windshield. Sold it after one ride and got a Super ATV flip up. Half didnt seem to have much of a purpose to me.
Lower Doors.- I put a pair of the Honda lower doors on my first Talon and a pair of AJK lowers on my 4 seater. I didnt care for how the Hondas mounted and were a pain to install. AJK are nice powder coated aluminum and simple to install.
Bags - I don't know a ton about Hondas, but I plan to go with PRP bags. I have read some of the PRP have more capacity
Aluminum Bumpers. I bought both front and rear with my machine. I used the front and sold the rear. I didnt care for how it mounted and stuck out. I opted for no rear bumper and havent missed it.
All the Honda brand stuff is pricey and can usually be done cheaper.
If you ride Rocks I'd suggest upgrading skid plate, high clearance front arms and high clearance radius rods. I used Factory UTV for skid and L&W for arms and rods. These along with windshield, nerf bars, tires, would be the first things I added.
Here is a link to my build if interested. I just sold the 2 seater and swapped most the stuff to the a 4 seater.
