It depends of course on what you want to use it for.
I use mine mostly on twisty mountain back roads, with an occasional track day.
Fork springs for my weight and Race Tech emulators made the front work extremely well.
Adding Honda 600f4i front calipers with EBC HH pads made the brakes fantastic.
Penske's cheapest shock, sprung and valved for my weight and riding style made the rear suspension as good as the front.
A K&N filter,, aftermarket pipe and some re-jetting to match gave it a little extra power. For track days, it could use even more power.
I can't think of anything else it needs...
