At the heart of the 2012 Kymco MXU 500 4x4 IRS atv motorcycle, Kymco features a 498.5 cc (30.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 18 HP (13.1 kW) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 36.1 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 500 4x4 IRS measures 306 kg (675 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (17 kg per horsepower). Rider ergonomics and chassis geometry center around a 848 mm (33.4 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,293 mm (50.9 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
