At the heart of the 2010 KTM 300 EXC enduro - offroad motorcycle, KTM relies on a 293.2 cc (17.9 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 72.0 x 72.0 mm (2.8 x 2.8 inches).
On the scales, the 300 EXC measures 103.1 kg (227 lbs) dry. Rider ergonomics and chassis geometry center around a 985 mm (38.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 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.
