2009 KTM 105SX

Robust, light and the measure of all things in terms of power and performance: its power-to-weight ratio has been the decisive argument in the its class for years. No bike whips through the curves better and yet remains easily controllable. With its re-vamped chassis and broadly usable rev range, the 105 SX leaves the competition’s 4-strokes in the dust. Details like the adjustable CNC-machined triple clamp are normally available only on expensive factory bikes. But they’re standard equipment in our SX models.
