You didn't ask but I see the stock front tire (death wing) on there. If you're shelling out for upgrades it would be a good time to look at something else..shinko 241, etc. The stocker isn't as bad if you're staying on pave but an upgrade will be night and day if you get into anything loose.
The pegs are a cap shoot...I got 'steel' $15 pegs but they're some light. They've taken a few knocks and are still fine though.
I went with an o ring chain and a 45 rear. 1st gear is usable again and is low enough for all but the gnarliest glomming through bad trails.
My stock chain was stretched out at 2500kms and after that it needed adjustment to after every couple rides. If you're swapping sprockets just get an o ring chain and set it and forget it pretty much.
With 14/45 mine let's me jump on the highway for short jaunts at 100-105 km/h easily. A 50 will do that too but at revs that feel higher than necessary...but the 45 makes 1st back into a usable gear.
Cheap hand guards will save your levers if and when it takes a nap on its side plus they shield your hands from a lot of wind on cooler days.
Likely close to the same stuff others will say....
I'll let them chime in.
