FULL-SCREAM AHEAD
There are very few sounds that can't be beaten: the crack of a soda can on a blistering hot day, the ping of the perfectly executed golf shot, and the scream of a 125 cc 2-stroke full throttle. The KTM 125 SX takes its leads directly from the KTM Factory Racing team for pure performance, pure results. Like the sound it makes, you won't forget it.
