Positioned in KTM's cross - motocross motorcycle lineup, the 2017 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 99.8 kg (220 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 1,485 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.
