I just started riding my 2012. In January I traded in my 2007 that I rode for 87,000 miles. A couple things that I noticed and really like are the improvement in the sound, no more high-pitched engine revving noise. Also, even though I replaced the throttle cam on the 2007 with an aluminum cam, the 2012 is smoother on the acceleration. Thumbs up Yamaha for just making this thing better!
