The 2013 KTM 125 SX is built on a modern frame which is made of lightweight, high strength, chrome-molybdenum steel section tubes. This construction gives it an ideal mix of longitudinal and torsional stiffness.
The frame’s center piece is a 1-cylinder 2-stroke engine, water-cooled, with reed intake and exhaust control. Te engine is paired with a six speed transmission and has a displacement of 24.8 cm³. It’s also worthy of being mentioned that for 2013, the engine braces to the cylinder head have been optimized, along with their attachment to the frame.
Another significant upgrade made for 2013 is the new, more refined WP monoshock and the KTM linkage system. Thanks to the new modifications, the monoshock offers improved damping, more traction and even higher reserves against bottoming out. Like usual, rebound and compression damping (high and low speed) can be adapted individually to the track and rider.
