Overview

When KTM launched its first big Adventure in 2003, nobody was talking about "mini-trail" bikes yet. Twenty years later, the recipe has caught on so well that the small-displacement adventure segment is overflowing with serious contenders. Honda, Royal Enfield, Yamaha — all have their entry ticket in this category that appeals just as much to beginners as to riders looking for a lightweight second mount. In this precise context, the KTM 390 Adventure X 2025 arrives with a clearly stated ambition: not to play at pretending to be a real trail bike, but to establish itself as a compact GT, built for tarmac and sensible dirt tracks.

KTM 390 Adventure X

The first visual impression cuts sharply from the previous generation, which looks retrospectively quite tame. The new face borrows from the design brief of the large 1390 Super Adventure, with its voluminous fairing featuring pronounced cheeks and redesigned hand guards that promise significantly more serious wind protection on the motorway. The square-section front mudguard is reminiscent of motocross machines, creating a deliberately blended identity. Aesthetically, the X ticks more boxes than the old model, even if KTM's style remains divisive — orange obligatory. What is certain is that it can no longer be mistaken for a generic entry in its category.

Beneath this redesigned bodywork, the 398 cc unit derived from the latest Duke serves as the backbone. This single-cylinder four-valve engine, with its 89 mm bore and 64 mm stroke, produces 45 horsepower at 8,500 rpm and 40.2 Nm at 7,000 rpm. The figures fall just under the A2 licence threshold, opening the bike up to younger riders. KTM revised the cylinder head, injector, and intake to gain ground clearance by raising the engine, while the very compact exhaust saves two kilograms on the scales. At 165 kg dry, the X remains manageable and the 825 mm seat height is not out of reach. Top speed is rated at 160 km/h, consistent with its road-oriented positioning without sporting pretensions.

What truly distinguishes the X from its sister model, the R, is a list of deliberate compromises made to bring down the price. The 43 mm WP inverted fork with 200 mm of travel is non-adjustable, the screen drops from TFT to LCD, and cornering traction control along with Rain mode disappear. Two riding modes remain — Street and Offroad — along with rear-disengageable ABS and Bybre braking with a 320 mm disc up front and 240 mm at the rear. The steel trellis frame is shared with the SMC R and Enduro R of the same displacement, demonstrating genuine platform coherence. For the intended audience — the occasional tourer or A2 rider who wants to explore without overcomplicating things — these concessions are perfectly acceptable.

The outcome of this equation is written in the price. At €5,799, the KTM 390 Adventure X 2025 comes in €1,500 less than the R, the same gap as the previous generation. Against a Royal Enfield Himalayan or a Honda CB500X, the KTM plays the card of engine dynamism and a sporty chassis, at the expense of suspension comfort that its rivals offer more generously. In a 2025 lineup that also sees the arrival of the KTM 390 Enduro R and KTM 390 SMC R, the X clearly occupies the least radical, most civilised slot. That is not a flaw — it is a deliberate choice that matches a mixed daily use profile, urban and weekend riding alike. For anyone wanting a small, versatile machine without breaking the bank, it genuinely deserves a proper KTM 390 Adventure X test ride before making any decision.
