Picked up a 2010 KLX250SF from a friend in March '13 with only 300 miles! He bought it from a dealer back in December '12 so it is basically new and he was having me break the engine in for him so I put most of those 300 miles on anyway!
Great shape, no mods yet but I have handguards and a rack to put on the back but I don't have time to do anything until I finish my degree. I took the FMF pipe off and sold it because it was too loud for commuting to work at 5:30am, the neighbors already put up with my car.
As of January '14 it has about 1300 miles on it. It's my first bike and I'm loving it.
