At the heart of the 1998 KTM 380 SX cross - motocross motorcycle, KTM relies on a 380 cc (23.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 78.0 x 77.0 mm (3.1 x 3.0 inches).
On the scales, the 380 SX measures 103.7 kg (229 lbs) dry. Rider ergonomics and chassis geometry center around a 925 mm (36.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 2.4-liter (0.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
