2015 KTM 125SX: KTM’s engineers have developed new
mapping and ignition curves for the 125SX two-stroke to
help curtain detonation under hard loads.
2015 KTM 150SX: Much like its little brother, the 125SX, the
KTM 150SX gets a new ignition curve to go along with the
4CS forks, 260mm front brake rotor and new shock linkage.
2015 KTM 250SXF: A stronger, but lighter clutch is the only
engine change on the 250SXF, but it gets 2mm less fork
offset via a small front axle and pulled back fork lug.
