I hemmed and hawed over about 6 different bikes and finally settled on a new YZ450F today. I paid $8700 out the door and they gave me 25% off the GYTR Tuner, so I picked that up as well. The majority of my gear is at my buddy's house so I can't go put in a good ride until I get my stuff back, but I did take her out for a quick spin. I can already tell you that this bike is faster in stock form than my last bike (07 CRF450R) and the throttle response is just out of this world. This is my first EFI bike though, so take that for what it's worth. I plan on doing a review and posting it up within the next couple weeks. If you guys have any tips for setup or whatever, let me know!
