I picked up my (new to me) 2008 with about 2250 miles on it today in Pittsburg and it fit rather easily with only the removal of the mirrors. It was layiing all the way down on the floor with a few inches to spare length & hight/width! A bit of a bear for me (66 year old guy) and seller (younger guy) to get it in but relatively easy for me to get out when I got it home to Frederick, MD.
Took a short test ride. It is stock except for hand guards. Sure feels TALL, even though I'm 5'11" (since when I last rode dirt bikes they had about 4" of suspension travel). Will be doing the suspension adjustment/lowering. Also geared REALLY tall. Will be chaning sprocets. Motor felt torquier than I was expecting after reading thorough all the posts on this thread (but most of my dirt bike experince is on 125cc Sachs/PENTON 2-stokes) so I was pleasantly surprized. Clutch felt a little grabby and didn't engage at all until almost all the way out - but I'll probably get used to that. Also noticed a little of the jerkiness just off idle.
I think I have a LOT to learn/re-learn about dirt riding after bieing away from it for 25+ years!
