Built around Kymco's atv motorcycle platform, the 2024 Kymco MXU 300 T3B relies on a 270 cc (16.5 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 21 HP (15.3 kW), transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) 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 MXU 300 T3B measures 235 kg (518 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,160 mm (45.7 in) wheelbase engineered for quick, flickable steering geometry. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
