At the heart of the 2017 KTM 125 XC-W enduro - offroad motorcycle, KTM relies on a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches).
On the scales, the 125 XC-W measures 91 kg (201 lbs) dry. Rider ergonomics and chassis geometry center around a 960 mm (37.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,471 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
