At the heart of the 2011 Kymco MXU 300 RL atv motorcycle, Kymco pairs a 366.9 cc (22.4 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 18.8 HP (13.7 kW) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 51.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the MXU 300 RL measures 215 kg (474 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 72 km/h (45 mph).
