The KTM RC 390 is powered by a 373.27 cc liquid-cooled, single-cylinder engine that produces 42.9 bhp (43.5 PS) at 9,000 rpm and 37 Nm of torque at 7,000 rpm. Paired with a 6-speed gearbox and a bi-directional quickshifter, power delivery is sharp and linear - exactly what you want when you're leaned over mid-corner on a track.

The engine meets BS6 Phase 2B emission norms and comes with ride-by-wire throttle, enabling features like cornering traction control and selectable ride modes. ARAI-certified mileage stands at 26.6 kmpl; real-world figures from owners typically range between 23-28 kmpl depending on how enthusiastically you ride.

Suspension duties are handled by a 43 mm WP APEX USD front fork and a WP APEX rear monoshock, both fully adjustable for preload and rebound - a feature you'd usually only find on bikes costing significantly more. Ground clearance is 153 mm and the wheelbase measures 1,355 mm, giving the RC 390 a taut, confident feel at speed.

Braking is a strong suit: a 320 mm petal disc up front and a 230 mm petal disc at the rear, governed by Bosch lean-sensitive cornering ABS. The slipper clutch prevents rear-wheel hop under aggressive downshifts. Kerb weight is 172 kg, which is impressively light for a fully-faired sportsbike with this level of equipment.

Featuring a 5-inch TFT instrument cluster with Bluetooth smartphone connectivity, turn-by-turn navigation support, and multiple display themes, the RC 390's cockpit punches well above its price. Lighting is full-LED throughout.

For the money, the KTM RC 390's specification sheet is remarkable. Cornering ABS, quickshifter, ride-by-wire, traction control, and fully adjustable WP suspension - these are features that typically cost Rs 5-8 lakh in the Indian market. The bike's 172 kg kerb weight keeps things manageable, and the 13.7 L fuel tank provides a real-world range of roughly 350-380 km before you need to stop. If you're upgrading from a 200-250cc bike or stepping into your first proper sportsbike, the RC 390 offers a credible mix of hardware, electronics, and performance at a price point few can match.

## FAQs

**What is the engine displacement of the KTM RC 390?**
The KTM RC 390 is powered by a 373.27 cc liquid-cooled, single-cylinder engine that produces 42.9 bhp (43.5 PS) at 9,000 rpm and 37 Nm of torque at 7,000 rpm. It meets BS6 Phase 2B emission norms and is paired with a 6-speed gearbox with a bi-directional quickshifter.

**What is the kerb weight and fuel tank capacity of the KTM RC 390?**
The KTM RC 390 has a kerb weight of 172 kg, which is impressively light for a fully-faired sportsbike with this level of electronics. The fuel tank holds 13.7 litres, giving a real-world range of approximately 350-380 km per fill on mixed riding.

**What suspension does the KTM RC 390 use?**
The KTM RC 390 uses a 43 mm WP APEX USD (upside-down) front fork and a WP APEX rear monoshock, both fully adjustable for preload and rebound. This level of suspension adjustability is rare at this price point and makes the RC 390 well-suited for track days. Seat height is 835 mm and ground clearance is 153 mm.

**Does the KTM RC 390 get ABS, and is it cornering ABS?**
Yes - the KTM RC 390 comes standard with lean-sensitive cornering ABS (Bosch 9.1 MP unit) on both variants. This means the ABS adjusts its intervention based on the lean angle of the bike, preventing wheel lock-up even mid-corner. A slipper clutch is also standard to prevent rear-wheel hop under aggressive downshifts.

**What is the ARAI-certified mileage of the KTM RC 390?**
The KTM RC 390 has an ARAI-certified mileage of 26.6 kmpl. In real-world conditions, owners report 23-25 kmpl in city traffic and 26-28 kmpl on highways at moderate speeds. Riding aggressively on a racetrack will drop fuel economy significantly below these figures.
