The first thing I recommend you do is get some new rubbers. Any of the stock tires are just the cheapest, understandably to keep the msrp down but I highly suggest getting better rubber. I have Michelin Pilot Road2 160/60/17 rear and kept the same size 110/70/17 on the front with no mods what so ever. Just had to move the chain guard back a half inch but that was it. As long as you stay with the 60 or lower profile on the rear you will be fine. I cannot even begin to describe the positive difference in acceleration and deceleration traction control, higher speed stability, and stopping distance. I know you might think you could loose speed performance but it truly is negligible. If you are a beginner these benefits could save your life, really.
