Built around KTM's sport motorcycle platform, the 2016 KTM RC 390 utilizes a 373.2 cc (22.8 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 44 HP (32.1 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 117.9 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the RC 390 measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
