The 390 Adventure X is built around a 398.63cc single-cylinder, DOHC, liquid-cooled engine - the same unit that powers the pricier 390 Adventure. It makes 46 PS at 8,500 rpm and 39 Nm of torque at 6,500 rpm. The six-speed gearbox comes with a slipper-assist clutch and a bi-directional quickshifter as standard, allowing clutchless upshifts and downshifts.

The chassis is a steel trellis frame - shared across KTM's 390 family - running WP Apex suspension at both ends. Up front: a 43mm inverted fork with 200mm of travel, non-adjustable. At the rear: a WP monoshock with 205mm of travel and preload adjustment only. Wheels are cast alloy - 19-inch front with a 100/90 tyre, 17-inch rear with a 130/80 tyre - and both are tubeless.

Braking comes from a 320mm front disc and a 240mm rear disc, managed by dual-channel ABS with a dedicated off-road mode that allows some rear wheel slip on loose surfaces. Ground clearance is 227mm, the wheelbase is 1,464mm, and the seat height of 825mm makes it accessible for most medium-height riders.

Electronics are solid for the price: a 5-inch colour TFT display with Bluetooth connectivity and turn-by-turn navigation, USB Type-C charging port, all-LED lighting, and a twin-projector LED headlight. What the X does not get - compared to the standard 390 Adventure - is cornering ABS, ride modes, and adjustable brake/clutch levers.

Fuel tank capacity is 14.5 litres, giving a practical highway range of 400+ km. Kerb weight is 181 kg. Owner-reported mileage sits around 26-30 kmpl depending on riding style; KTM has not published an ARAI figure for this variant.

Compared to its main rivals, the 390 Adventure X holds up well on paper. The Royal Enfield Himalayan 450 runs a 452cc engine but makes 40.1 PS - less than the KTM's 46 PS - and weighs around 196 kg wet. The BMW G 310 GS is lighter at 169.5 kg but makes only 34 PS from its 313cc engine, and its price of around Rs 3.89 Lakh makes it harder to justify. The X's spec sheet advantage is clearest in electronics: no sub-Rs 3.5 Lakh ADV in India currently offers a bi-directional quickshifter alongside a full-colour TFT and Bluetooth navigation.

## FAQs

**What is the engine displacement of the KTM 390 Adventure X?**
The KTM 390 Adventure X uses a 398.63cc single-cylinder, DOHC, liquid-cooled engine producing 46 PS at 8,500 rpm and 39 Nm of torque at 6,500 rpm. It is paired with a 6-speed gearbox featuring a slipper-assist clutch and a bi-directional quickshifter as standard.

**What are the dimensions and kerb weight of the KTM 390 Adventure X?**
The KTM 390 Adventure X has a kerb weight of 181 kg, a seat height of 825mm, and a ground clearance of 227mm. The wheelbase is 1,464mm, making it a well-proportioned mid-size ADV that handles city riding and highway touring without feeling overly large.

**What suspension setup does the KTM 390 Adventure X use?**
The 390 Adventure X uses WP Apex 43mm inverted front forks with 200mm of travel (non-adjustable) and a WP rear monoshock with 205mm of travel (preload adjustable only). Both ends offer the same travel as the standard 390 Adventure - the key difference is the X's non-adjustable front fork.

**Does the KTM 390 Adventure X get ABS?**
Yes - the KTM 390 Adventure X comes with dual-channel ABS as standard across both variants. It includes an off-road mode that permits controlled rear wheel slip on loose surfaces. Cornering ABS is not available on the X; that feature is reserved for the standard 390 Adventure.
