Built around Ktm's cross - motocross motorcycle platform, the 2019 Ktm 350 SX-F utilizes a 349.7 cc (21.3 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 88.0 x 57.5 mm (3.5 x 2.3 inches) with a 14.0:1 compression ratio.
On the scales, the 350 SX-F measures 99.5 kg (219 lbs) dry. Rider ergonomics and chassis geometry center around a 950 mm (37.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,485 mm (58.5 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.
