No, not a mountain bike. I just bought it today from a private seller for $2,000. Don't make fun of me, it's my first bike. The last time I rode anything was 125cc dirt bikes a couple years ago, so I didn't go with the Yamaha R6 . I went with the Kawasaki Ninja 250 (2004 with 600 original miles on it). Here's a couple pics of it.
