Overview
Performance & Engine
The RC 390 uses a 373.27 cc single-cylinder, liquid-cooled DOHC engine with Bosch EFI. It produces 43.5 PS at 9,000 rpm and 37 Nm at 7,000 rpm. Riders appreciate its lively character and stronger low-end power, thanks to updated mapping and a bigger airbox. The engine’s bore and stroke (89 mm x 60 mm) and 12.88:1 compression ratio help deliver strong mid-range performance, making quick overtakes on highways easy.
The bike’s liquid cooling system, with a curved radiator and two fans, keeps it running smoothly even in hot Indian weather or during long track sessions. Forced wet-sump lubrication adds to its reliability. Features like MTC traction control with different modes, Supermoto ABS for controlled rear-wheel slides, and a power-assisted slipper clutch help manage the engine’s strong power. Many owners call it a “monster” in the 400cc class because of its speed and looks.
The RC 390 comes with a smooth 6-speed manual gearbox and a power-assisted slipper clutch that stops the rear wheel from hopping during hard downshifts, which is great for aggressive riding. The Quickshifter+ lets you shift up or down without the clutch above 2,500 rpm, making gear changes faster and keeping up momentum on winding roads. Power goes to the rear wheel through a chain drive and a 15/45 sprocket setup for quick acceleration. The short gear ratios match the bike’s sporty nature, though you need to be precise in traffic. Overall, the transmission feels accurate and built for racing, adding to the bike’s sharp character.
The RC 390 can reach a top speed of about 160-170 kmph, and hitting over 160 kmph in top gear is easy on open roads. Its aerodynamic winglets and sporty riding position help you ride at these speeds without too much wind hitting you. In real-world Indian tests, the speedometer often shows 169-170 kmph before the power starts to drop, mainly due to gearing and aerodynamics. Cornering ABS works smoothly at high speeds to keep you safe.
Mileage & Fuel Efficiency
The RC 390 has an ARAI-certified mileage of about 29 kmpl in India, based on controlled tests with the BS6 engine. With its 13.7-litre fuel tank, you can expect a range of over 390 km per fill-up. This mileage is helped by EFI tuning and a ride-by-wire throttle, but it’s lower than that of commuter bikes because the RC 390 is built for performance.
In real-world use, the RC 390 usually delivers 26-29 kmpl, with mixed city and highway riding averaging 29 kmpl. Expert tests report around 26.6 kmpl. In heavy city traffic, mileage drops to 22-25 kmpl, but steady cruising at 80 kmph can give up to 30 kmpl. Factors like rider weight, maintenance, and how hard you ride affect these numbers—aggressive riding often brings it down to 20-24 kmpl. For a supersport, this efficiency is good, and the 13.7-litre tank means you can go 350-400 km between stops.

Build Quality
KTM’s quality shows in the RC 390’s powder-coated orange trellis frame, which resists rust well even in humid places like Kerala. The frame has precise welds and reinforcements that give it a solid feel. The fairings and tank covers use high-quality ABS plastic and fit together tightly, with very few gaps or flex, even during hard cornering. The WP suspension, Brembo-style brakes, and CNC-machined triple clamps are built to a high standard, making the bike feel sturdy on rough roads.
The RC 390’s chain and swingarm bushings last well, even with spirited riding, and owners report fewer maintenance issues than with other bikes. The paint on the wheels and engine cases resists chips from highway stones, and the LED lights are well-sealed against dust, which is helpful during the monsoon. Weighing 172 kg, the bike feels both light and strong, showing careful engineering. Owners in India say the subframe is more durable than before, with fewer flex problems, and the overall build quality is better than most 400cc bikes.
Handling
The RC 390 is known for its excellent handling, thanks to its short 1,415 mm wheelbase and 66-degree rake, which make it easy to turn sharply on winding roads or city flyovers. The WP APEX 43 mm front forks with 125 mm travel give great feedback and absorb bumps well, even when braking hard on rough roads. The rear monoshock, which can be adjusted for preload and has 150 mm travel, keeps the bike stable over bumps and lets you lean confidently up to 45 degrees because of its low center of gravity.
Sticky 110/70-17 front and 150/60-17 rear tyres grip tenaciously in dry or damp conditions, aided by MTC and cornering ABS for error forgiveness. Quickshifter+ keeps momentum flowing, making mid-corner flicks effortless. In real-world tests, it outmanoeuvres heavier nakeds on twisties like Lonavala ghats, with neutral steering that inspires trust at 140+ kmph straights. The chassis rigidity eliminates wobbles, rewarding precise inputs for an addictive ride feel tailored to performance-hungry Indian riders.
Comfort
The RC 390’s sporty riding position takes some getting used to, but its 835 mm seat height and narrow design let most Indian riders put their feet flat on the ground, making it easier to handle in traffic. The 790 mm wide clip-on handlebars encourage a tucked-in posture for better wind protection above 120 kmph, and the rearset footpegs are spaced so even taller riders can ride 100 km without cramps. The seat has dual-density padding for more comfort on longer rides, though you might feel some vibrations below 4,000 rpm on bumpy roads.
The suspension works well in cities with lots of potholes, as the forks absorb sharp bumps and the rear monoshock can be adjusted for carrying a passenger, up to a total of 160 kg. The mirrors give a good view behind, and the slim 200 mm-wide tail helps you move through traffic. The pillion seat is small and high, with grab rails that are fine for short 50 km trips but not for long journeys. If you ride alone, your wrists may get tired after about 3 hours, but taking breaks helps. Cruising at 100 kmph on the highway is comfortable. Overall, the RC 390 is best for fun, aggressive rides over 300 km, rather than long-distance touring.
Styling
The RC 390 has an aggressive look, with sharp aerodynamic fairings, built-in winglets for downforce, and a muscular shape inspired by MotoGP bikes. The twin-pod LED headlamp with DRL gives it a fierce appearance, while the sharply shaped tank and compact tail add to its sporty style. The orange trellis frame stands out through the bodywork, and the single-sided swingarm and underbelly exhaust keep the design clean and focused.
The fairing lines help direct air smoothly, reducing drag at high speeds. The 5-spoke alloy wheels fit well in the arches, giving the bike a solid look. In India, this design stands out both in showrooms and on the road, mixing a modern, sharp style with KTM’s READY TO RACE image. The updated bodywork makes the bike look slimmer and gives a sense of speed, even when it’s parked.
