I love KTM's. My dad had a KTM 250 XC dirt bike a few years back.He got it from a friend for $200 not running. My dad cleaned the carb, got new plug, put some fresh gas in and it started right up. Thing sounded nasty. Gotta love 2 strokes.
if there was a line of all the 450s and i could choose any it would without question be the ktm sx450 as they are fun quads to ride outside of the track so easy to stunt on kinda like a z400
