Very nice new toy, I like those F650GS twins
The main bitts you are already searching for in the wanted section, I see from the picture you already have hand guard/lever protectors.
the tall screen makes the ride more of a joy
Engine bars are a must insurance as is the sump/bash plate if your going orf road. maybe bar risers, pegs, better tyres.
I still have the gouges from the stella in my bash plate. hand guards and engine bars have been restored to former glory from the 4 slow motion hardly moving at all offs, 3 and 4 was part of the 2nd really.
lots of other bitts to be had, but a personal to each riders wants and needs, look through the relevant sections lots of opinions and ideas some nice bits. some already mentioned above.
I have some of this nice stuff,

For distant/time in the saddle I have the TT high touring seat but, the air hawk is bliss and the lambs fleece is cooling
Enjoy

Biarritz blue if I'm not mistaken, I like it...........
I see your off for the stella, hence my mentioning. in the rally would be different , I went up in the sun, with one other bike came down in the dark
me and one other amongst a few other things I learnt 1. you can shake tea out of a tea bag and 2. eat my dust is not just a saying
