KTM 790 Adventure (2019–2020): The Lightweight Adventurer That Redefined Exploration

Introduction: A New Era of Adventure

When KTM introduced the 790 Adventure in 2019, it wasn’t just another addition to the adventure bike market—it was a statement. Designed to bridge the gap between hardcore off-road capability and long-distance touring comfort, this motorcycle quickly became a benchmark for riders who refuse to let terrain dictate their limits. With its 799 cc parallel-twin engine, cutting-edge electronics, and a chassis built to conquer both tarmac and trails, the 790 Adventure redefined what a middleweight adventure bike could achieve. After spending days testing this machine on rocky trails, winding roads, and highways, it’s clear why it remains a favorite among riders who crave versatility without compromise.

Design & Build: Purposeful Aggression

The KTM 790 Adventure looks every bit the rally-bred machine it is. Its angular bodywork, slim profile, and signature orange livery scream performance, while functional design elements like the low-slung 20-liter fuel tank (5.3 gallons) keep the center of gravity low for improved stability. The bike’s Chromium-Molybdenum steel frame isn’t just lightweight—it’s engineered to use the engine as a stressed member, reducing weight to a dry 189 kg (416 lbs) and creating a compact, agile package.

Standout features include the LED headlight, which casts a wide beam for off-road visibility, and the adjustable windscreen that deflects wind effectively at highway speeds. The spoked 21-inch front and 18-inch rear wheels (shod with Maxxis or Avon tires, depending on the market) are built to withstand rough terrain, while the 233 mm (9.2 inches) of ground clearance ensures rocky trails won’t leave scars on the underside.

Engine & Performance: Smooth Power Meets Adventure Tuning

At the heart of the 790 Adventure lies the LC8c parallel-twin engine, a 799 cc powerhouse delivering 95 PS (70 kW) and 88 Nm (65 lb-ft) of torque. What sets this engine apart is its tuning: power builds linearly, with torque peaking at a low 6,600 RPM, making it ideal for crawling over obstacles or accelerating out of corners. The twin balancer shafts minimize vibrations, a blessing on long hauls, while the PASC slipper clutch ensures smooth downshifts even on loose surfaces.

Fuel efficiency is impressive for a bike of this caliber. KTM claims 4.19 L/100 km (56 mpg), and during mixed riding, we averaged around 4.5 L/100 km (52 mpg), translating to a 450 km (280-mile) range—enough to outlast most bladders between fuel stops. The exhaust note is throaty without being obnoxious, thanks to a mid-mounted resonator that keeps noise levels adventure-friendly.

Chassis & Suspension: Confidence on Any Surface

The 790 Adventure’s WP APEX suspension is where KTM’s off-road DNA shines. The 43 mm USD forks and rear monoshock offer 200 mm (7.9 inches) of travel, soaking up everything from potholes to whoops with composure. While the setup leans slightly toward firmness for road stability, it never feels harsh, even when tackling jagged trails at speed. Preload adjustment on the rear shock simplifies adapting to luggage or passenger weight.

Braking is equally robust. Twin 320 mm front discs gripped by radial-mounted 4-piston calipers provide strong stopping power, aided by Cornering ABS. Off-road mode disables rear ABS, allowing controlled slides—a feature that’ll make gravel enthusiasts grin.

Electronics: Smarter Than Your Average Adventurer

KTM’s electronics suite is a masterclass in balancing control and freedom. Four ride modes (Street, Rain, Offroad, and optional Rally) adjust throttle response, traction control, and ABS behavior. Rally mode is the star here, letting the rear wheel spin up to 15% before intervention—perfect for sandy climbs.

The 5-inch TFT display is intuitive, offering customizable data like tire pressure (2.4 bar/35 psi front, 2.6 bar/38 psi rear) and fuel range. Heated grips and cruise control were optional extras that felt indispensable during chilly highway stretches.

Ergonomics & Comfort: Built for the Long Haul

With an 850 mm (33.5-inch) seat height, the 790 Adventure caters to taller riders, though the narrow seat front helps shorter legs reach the ground. The tapered handlebar adjusts over 30 mm, and the footpegs’ rubber inserts dampen vibrations—remove them for better boot grip off-road.

Wind protection is adequate but not luxurious; the adjustable screen buffers chest-level airflow, though taller riders might crave more height. The two-piece seat is firm yet supportive, and the optional heated seat adds winter versatility.

Competition: How Does It Stack Up?

The middleweight adventure segment is fiercely contested. Here’s how the 790 Adventure holds its ground:

• BMW F 850 GS: BMW’s offering matches the KTM in power (95 PS) but weighs 229 kg (505 lbs)—40 kg (88 lbs) heavier. The F 850 GS excels in touring comfort but feels less agile off-road.
• Yamaha Ténéré 700: Yamaha’s CP2 engine is bulletproof, and the Ténéré costs less. However, it lacks the KTM’s electronics (no cornering ABS or ride modes) and has a softer suspension setup.
• Honda Africa Twin (CRF1100L): Honda’s flagship dominates in tech and displacement but is bulkier and pricier. The 790 Adventure outmaneuvers it on tight trails.

The KTM’s trump card is its balance: it’s lighter, more tech-savvy, and more capable off-road than most rivals while still devouring highway miles.

Maintenance: Keeping Your Adventure Alive

Ownership costs are reasonable for a bike this sophisticated:
- Oil Changes: Use JASO MA2-certified 10W-50 synthetic oil (2.8L with filter). Replace every 15,000 km (9,300 miles).
- Valve Checks: Inspect every 30,000 km (18,600 miles). Intake valves: 0.10–0.15 mm (0.004–0.006 in); exhaust: 0.15–0.20 mm (0.006–0.008 in).
- Chain Care: The 118-link X-ring chain needs regular cleaning and lubrication. Check sprocket wear (16T front/45T rear) during tire changes.
- Coolant: Replace every 2 years or 30,000 km. Capacity: 1.6L (1.7 quarts) of ethylene glycol-based coolant.

For DIY enthusiasts, MOTOPARTS.store stocks everything from NGK LMAR9AI-10 spark plugs to WP suspension fluids. Upgrading to a high-flow air filter or installing a reinforced chain can enhance durability for off-road abuse.
