Technical Overview
2019 Ktm RC 390 R Technical Analysis & Specification Breakdown
Built around Ktm's sport motorcycle platform, the 2019 Ktm RC 390 R features a 373 cc (22.8 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 43 HP (31.4 kW), transferring power to the rear wheel through chain final drive. With a specific output of 115.3 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 R measures 147 kg (324 lbs) wet (curb), translating to a power-to-weight ratio of 0.29 HP/kg (3.42 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.
