Positioned in Kymco's atv motorcycle lineup, the 2012 Kymco MXU 300 Shaft Drive pairs a 270 cc (16.5 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 18.3 HP (13.4 kW), transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 67.8 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 MXU 300 Shaft Drive measures 216.8 kg (478 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 808 mm (31.8 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,184 mm (46.6 in) wheelbase engineered for quick, flickable steering geometry. The 12.49-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
