Built around KTM's enduro - offroad motorcycle platform, the 2010 KTM 250 SX-F utilizes a 248.6 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 76.0 x 54.8 mm (3.0 x 2.2 inches) with a 12.8:1 compression ratio.
On the scales, the 250 SX-F measures 98 kg (216 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 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
