The KTM RC 390 is a high-performance lightweight supersport motorcycle designed to bring track-ready dynamics to everyday riding. At its core lies a 373.3cc fuel-injected, liquid-cooled single-cylinder engine that generates 43.5 PS of maximum power at 9,000 rpm and 36 Nm of peak torque at 7,000 rpm. This potent powertrain is paired with a slick 6-speed transmission featuring an integrated slipper clutch, ensuring seamless downshifts and preventing rear-wheel chatter during aggressive deceleration. Engineered for precision handling and agility, the RC 390 utilizes a lightweight steel trellis frame that provides exceptional structural rigidity. The chassis relies on premium hardware from WP, including an upside-down front fork and a rear monoshock tailored to deliver sharp, responsive cornering feedback. Braking is handled by a substantial 320mm front disc and a 230mm rear disc, with a dual-channel ABS system included as standard equipment. Tipping the scales at a kerb weight of 166.8 kg, the motorcycle offers an outstanding power-to-weight ratio that appeals to performance-minded riders. Rooted in KTM's "Ready to Race" ethos, the RC 390 draws design and engineering inspiration from the Austrian manufacturer's success in Moto3 grand prix racing. Its aggressive ergonomics, aerodynamic styling, and focused geometry make it a popular choice for track-day enthusiasts, spirited commuters, and sports bike purists alike. Combining everyday practicality with genuine circuit capability, it has established itself globally as a benchmark in accessible sport motorcycling.
