I live at 7700 feet (CO mountains) and could easily ride from here to 4,000 and back to 11,000 in a day. In fact I can be at 11,000 in an hour, and down to 5,000 3 hours after that.
From what I read it sounds like at least some of the 07s have a serious problem with changing altitudes, and Yamaha has not fixed the problem yet.
I can't afford to buy a bike that doesn't perform well at altitude. Given that the 08 may or may not be fixed, I won't be buying one until I've read that the problem is fixed.
So now I'm looking at an 06 or perhaps earlier.
