Engine & Performance

The 1350 cm³ V‑twin (bore x stroke 110 x 71 mm) is tuned for punchy midrange and top-end shove, delivering 127 kW / 170 hp and 145 Nm / 107 lb-ft. That output translates to effortless highway passes, relaxed two-up touring, and immediate thrust when you twist the throttle out of tight corners.

Keihin EFI with 54 mm throttle bodies and Keihin EMS with RBW (ride-by-wire) plus twin ignition provide crisp fueling and precise response, while a 13:1 compression ratio underscores the engine’s efficiency and performance focus. Cooling is liquid with a water/oil heat exchanger, and lubrication is handled by forced oiling with three pumps—confidence-inspiring for hot days and sustained high-speed travel.

A 6-speed transmission works through a 40:76 primary drive and 17:42 secondary gearing, sending power to a 525 X-Ring chain. Real-world economy is respectable for the class at 6.7 l/100 km (1.77 gal/100 mi), and CO₂ emissions are rated at 139.5 g/km. With a 23 l / 6.08 gal fuel tank, it’s set for long stints between stops without the range anxiety. The electric starter and twin-ignition system further improve everyday usability and reliability.

Handling, Comfort & KTM 1390 Super Adventure S Seat Height

Chassis confidence starts with WP SAT (semi-active technology) suspension: a 48 mm upside-down fork up front and a semi-active shock at the rear, both offering 200 mm / 7.87 in of travel. The setup keeps the bike planted on fast pavement and composed over broken surfaces, adapting to changing conditions without fuss.

Geometry is stability-first with a 1558 mm / 61.34 in wheelbase (adjustable by ± 15 mm) and a 65.2° steering head angle. Ground clearance is 223 mm / 8.78 in, while cast aluminium wheels (3.50 x 19" front, 5 x 17" rear) and 120/70; 170/60 tire sizes strike a sweet balance for sporty road use and light off-pavement stretches.

The KTM 1390 Super Adventure S seat height is adjustable between 847 and 867 mm (33.35/34.13 in), helping riders dial in comfort and reach. Shorter riders may prefer the 847 mm setting, while taller riders and those carrying luggage might appreciate the added legroom at 867 mm. The tapered aluminum handlebar (Ø 28/22 mm) aids leverage at low speeds and comfort over distance. At a wet 250 kg / 551 lbs, the KTM 1390 Super Adventure S weight is competitive for a feature-rich ADV; you feel the heft in parking lots, but once rolling, the semi-active suspension and geometry make it shrink around you.

Equipment & Features

Stopping power comes from Brembo hardware: dual 320 mm / 12.6 in discs clamped by radially mounted 4‑piston front calipers, and a 267 mm / 10.5 in rear disc with a 2‑piston caliper. The frame is a powder-coated Chromium‑Molybdenum steel trellis with an aluminum, powder-coated rear subframe—strong, light, and service-friendly. Cast aluminium wheels keep unsprung weight reasonable, and the 525 X‑Ring chain handles the V‑twin’s torque reliably.

Electronics and engine management are handled by Keihin EMS with RBW and twin ignition, ensuring refined throttle control. The liquid cooling system with a water/oil heat exchanger, plus robust lubrication, is built for sustained performance in varied climates.

Who Is the 2025 KTM 1390 Super Adventure S For?

This bike is ideal for experienced riders who want a powerful, road-biased adventure machine that still handles light off-pavement diversions. Daily commuters will appreciate the smooth fueling and upright ergonomics, while weekend tourers can make full use of the 23 l tank and semi-active suspension for long, fast days. Newer riders may find the combination of 170 hp and a 250 kg wet weight intimidating, but seasoned riders will enjoy the effortless pace and stability.

Torquepedia Verdict

If you’re shopping the big-bore ADV class with a performance tilt, the 2025 KTM 1390 Super Adventure S is a standout. The engine’s 127 kW / 170 hp and 145 Nm deliver serious thrust, while WP SAT suspension, Brembo brakes, and well-judged geometry keep it composed when the pace lifts.

Strengths include the adjustable seat height, stable chassis, long 23 l tank, and refined fueling via Keihin EMS with RBW. Its main compromises are the inevitable size and mass at low speeds. Overall, the 2025 KTM 1390 Super Adventure S specs and on-paper package make it a top-tier choice for riders prioritizing performance touring with real-world versatility.
