If you read this post, there's a bunch of things you might find useful on your bike.
I notice that you don't have a fork brace on there.
An upgrade to the front and rear suspension might be nice.
A change from the stock seat is useful.
A USB outlet and a 12v outlet and a voltmeter if you plan on running heated gear and other electronics.
Change up the mirrors to something more aerodynamic.
Maybe you will like the tank grip skins made by Tech Spec.
A tool tube is a useful thing to have.
I like reflective rim tape. It comes in black too if you don't like the daytime look.
Hwy pegs make longer distances much easier to handle.
You might like a different handlebar, like the stronger ATV ones.
Adjustable and/or folding and/or shorty levers might be something you like.
Do you ride with GPS? If so, then a mount of some sort will be needed.
It never ends....
