Engineered by Ktm for the cross - motocross motorcycle segment, the 2023 Ktm 300 SX features a 293.2 cc (17.9 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 72.0 x 72.0 mm (2.8 x 2.8 inches).
On the scales, the 300 SX measures 99.4 kg (219 lbs) dry. Rider ergonomics and chassis geometry center around a 958 mm (37.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,482 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 7.2-liter (1.9 US gal) fuel tank paired with a rated consumption of 2.79 L/100 km provides an estimated theoretical range of roughly 258 km (160 miles) between fill-ups.
