Built around KTM's enduro - offroad motorcycle platform, the 2025 KTM 150 EXC relies on a 144 cc (8.8 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 58.0 x 54.5 mm (2.3 x 2.1 inches).
On the scales, the 150 EXC measures 97.8 kg (216 lbs) dry. Rider ergonomics and chassis geometry center around a 963 mm (37.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,489 mm (58.6 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
