Hey JDbobber! Welcome!
Lots of good advice here.
Though, I think I'm with Bobber-bomb in so far as, ride it for a bit first. Upgrades tend to be pretty subjective I think, depending on how you use the bike.
I think I'm one of the few around here that hasn't changed out the suspension (yet), and I ride on some fairly rough roads where I live. But I'm probably one of the lighter riders here, and my seating position is a long ways from stock now. (high bars, forward controls).
Having said that, I don't tend to ride it very far, and rarely, for more than an hour at a shot, I would literally run out of gas about 80km short of the next available gas source if I was to try and travel out of town on it. I am, however, also on my 4th seat, and still, I am seriously considering a suspension upgrade as my next "need to get done" Mod.
As for rideability, This is probably one of the easiest, most forgiving bikes I have ridden. My only suggestion is don't yank on the throttle until you've had some time in the seat!
I look forward to seeing what you do with it in the future!
