2017–2019 · Adventure · Buyer's Guide
Orange Attack, Middleweight Reach
The 1090 Adventure takes KTM's 75° V-twin and builds a tall, lean adventure bike around it that still feels orange. It makes 125 hp and 80 lb-ft from 1050 cc, and that's enough to feel lively without ever overwhelming you. The motor has real personality. It wants to be revved, it pulls hard out of a corner, and ride-by-wire maps plus MTC traction control keep it civil when grip runs out. The steel trellis frame, 19-inch front wheel and 8.7 in (220 mm) of ground clearance tell you where its head is: in the mountains, on long days, with a trail waiting at the end.
It shines at real road pace. It's calm at highway speed, has plenty of lean clearance on a pass, and your passenger will be comfortable enough to stay aboard. Here's the honest part. Suspension travel is 7.3 in (185 mm) up front and 7.5 in (190 mm) at the rear, short of what I expect from a serious off-road ADV, and the fork has no adjustment at all. Only the shock takes preload. The fuel system needs watching as the bike ages: hot-start trouble, pump failures, a fuel gauge that sticks on full and some cold stalling. Buy a well-maintained one, fit a fresh pump and filter, and it rewards you.
Spec sheets don't ride bikes, but they set the baseline.

Safety
Much of what I know about this bike comes from years of listening: paddock talk, club nights, long chats with owners and the messages riders send me directly. For the 2017–2019 1090 Adventure the pattern is clear. The praise centers on the engine, the chassis off-road and how well it holds up over time. The complaints are scattered and individual.
Riders keep coming back to the motor. They describe it as strong in the midrange and free-revving up top, and they find it as engaging on a trail as on pavement. Owners also report trouble-free miles once a few early niggles were sorted, from an engine it shares with the 1190. Off-road, many say the chassis and WP suspension work straight from the crate, and some rank it the most capable in its class without changes.
No single gripe gets repeated much. Shorter riders find the seat intimidating at walking pace and when stopping on uneven ground. Taller riders get buffeting from the stock screen on the highway. Some call the very bottom of the rev range a bit fluffy, which asks for careful clutch work in technical terrain. Others point out that the side stand mounts to the engine case and can be damaged in a hard hit, and that a bent brake pedal can stress an internal bearing.
Air intake / airbox sealing
Early models could suffer from poorly seated airbox covers, allowing dust ingress. Aftermarket gaskets and pre-filters offer reliable fixes.
Fuel pump and/or fuel tank vent issues
Recurring reports of hot-start problems and occasional fuel pump failures, often traced to clogged filters or tank vent blockages. Replacing pump and filter is a common preventive measure.
Fuel level sensor stuck on full
Some owners report the fuel gauge indicating full even when the tank is low, requiring sensor modification or replacement to fix.
Brake pedal bearing stress
The rear brake pedal mount places lateral stress on an internal bearing; bending the lever in a fall can damage the bearing, requiring careful straightening or replacement.
Cold start stalling
Some owners report the bike stalls repeatedly when starting from cold, requiring multiple restarts. The issue may improve with use or after exhaust modifications.
Oil leak from ignition cover gasket
A few owners have experienced oil weeping from the ignition cover, requiring gasket replacement on low-mileage bikes.

Forget spec-sheet bragging. Here's who the 1090 Adventure is actually built for.
This is your bike. It's comfortable enough for 300-mile days and sharp enough to enjoy every bend on the Blue Ridge, and it has the character to keep the ride interesting.
Made for Black Hills · Blue Ridge Parkway · Cherohala Skyway
It's stable, comfortable two-up and has a 6.1 gal tank for the long legs between parks. Sort the fuel pump before a big trip. It's a sportier partner than a full-dress tourer.
Made for Beartooth Highway · Blue Ridge Parkway · Going-to-the-Sun Road
The 19-inch front and good clearance handle graded BDR gravel. The short travel and fixed fork won't love rough sections, though. Seal the airbox and carry a spare fuel filter.
Made for AZBDR — Arizona Backcountry Discovery Route · California BDR South · COBDR — Colorado Backcountry Discovery Route

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this KTM 1090 Adventure. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
