Positioned in KTM's enduro - offroad motorcycle lineup, the 2011 KTM 300 EXC relies on a 293.2 cc (17.9 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 22.8 HP (16.6 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 77.8 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the 300 EXC measures 103.1 kg (227 lbs) dry, translating to a power-to-weight ratio of 0.22 HP/kg (4.52 kg per horsepower). Rider ergonomics and chassis geometry center around a 985 mm (38.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
