Think "unbridled 2-stroke performance" and you'll probably see a KTM 250 SX in your mind's eye. For good reason too - there isn't much to compare it to. The KTM 250 SX takes that even further with a slew of fresh chassis enhancements, making it even more of a legend and one deserving of the record books.
