Positioned in KTM's cross - motocross motorcycle lineup, the 2016 KTM 250 SX pairs a 249 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 66.4 x 72.0 mm (2.6 x 2.8 inches).
On the scales, the 250 SX measures 95.9 kg (211 lbs) dry. Rider ergonomics and chassis geometry center around a 992 mm (39.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,495 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
