There are some things that can be improved, as with any bike, but essentially it'll do what you want as it is. I would always recommend living with it for a while and getting to know it. That way you'll be able to work out for yourself what needs work and what your priorities are. It'll save you money in the long run.
I've seen a lot of people hit the accessory catalogues hard as soon as they get their bikes and then come to regret some of their decisions later, and I'm guilty of that! Had I known what I do now, I never would have bought Yamaha panniers, handguards or an Akrapovic exhaust; all of which have gone! I would have spent the money saved on improving the suspension, but it took me 10,000 miles of riding to work that one out!
Ride, enjoy and ideas for mods will come to you naturally.
