Built around KTM's cross - motocross motorcycle platform, the 2015 KTM 450 SX-F utilizes a 449.3 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 95.0 x 63.4 mm (3.7 x 2.5 inches).
On the scales, the 450 SX-F measures 105.5 kg (233 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 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
