2020 790 Adventure - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the 790 Adventure is 94hp and 88 Nm of torque - strong numbers for what it is.
-
⛽
Large fuel range: With a 20-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.
Considerations
-
📏
Tall seat height: A 850 seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Brake disc and pad wear
2x 320mm discs. ABS up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by APEX 43mm WP upside-down forks up front and WP monoshock at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the 790 Adventure means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The CroMoly Tubular Steel, Engine as Stressed Member, Subframe: CroMoly Steel Trellis chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
790 Adventure - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2020 KTM 790 Adventure should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept 790 Adventure settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for a 790 Adventure's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.
Carburetor upkeep
A 790 Adventure that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
