Connected, Light, Offroad-Ready
The 790 Adventure is the middleweight KTM that never gave up on dirt. The 799 cc LC8c parallel twin makes 95 hp and 64 lb-ft, enough to hold interstate speed all day without dragging around heavyweight mass. What defines this generation is the hardware wrapped around that engine: a 21-inch front wheel, an 18-inch rear, 7.9 in of travel at both ends, 9.2 in of ground clearance and WP APEX suspension you can dial in yourself. Cornering ABS, ride modes, wheelie control and KTM Motorcycle Traction Control run behind a TFT display with smartphone connectivity, and a steering damper is standard.
On the road it feels lean rather than large, and that is the whole point. This is a bike for riders who plan a route through the dirt sections instead of around them, and who still want a 5.3 gal tank and highway manners good enough to make the trailhead in one day. The honest caveat: at 33.1 in the seat is tall even with the adjustable seat height, final drive is chain, and a lot of what makes a travel bike easy to live with sits on the options list rather than in the standard spec. Build it deliberately and it ages into a serious tool.
Spec sheets don't ride bikes, but they set the baseline.

Safety
Hit the starter and the parallel twin does what a parallel twin does: a hard, uneven pulse you feel through the pegs at low revs that smooths into a steady hum once you are rolling. Standing up is natural. The bike is narrow where your knees meet it, and the seat lets you shift your weight around instead of locking you into one spot. At real road pace the 21-inch front takes a beat longer to fall into a corner than a street bike would, then settles and stays put, and you run out of nerve well before the bike runs out of lean angle. The TFT stays readable in hard sun. Fill the 5.3 gal tank, ride four hours, and what ends the day is your schedule, not your back.
This part isn't mine. It comes from what owners have told me over the years, at club nights and rallies, and in the messages that land after somebody's first long season. On the 790 Adventure those accounts agree closely on what the bike does well, and split on one open question.
The engine draws the most comment. Owners describe a twin that pulls hard through the middle and keeps going when they ask for more, easy to meter out on loose ground and lively once the surface firms up. Highway composure is the next thing they raise; nobody reports the bike getting busy or nervous at a steady clip. On moderate terrain most say the suspension and wheels are enough bike for the ground they actually cover, and the rider aids and the dash get credit for keeping all of it manageable.
The critical thread is narrow and stubborn. Camshaft and rocker arm wear keeps coming up, along with repair bills owners call expensive. A share of them think the problem has been sorted on later builds, others aren't convinced, and the two camps haven't converged. Every so often a rider also mentions that tight, technical going asks more physical effort here than a lighter middleweight would.
No widely-reported issues on record.
Where this KTM 790 Adventure pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the 790 Adventure is actually built for.
This is the middleweight you want when the going turns technical: 21-inch front, 7.9 in of travel and traction control you can lean on. Budget for underbody protection before your first Moab trip.
Made for Bar M / Kane Creek · Imperial Sand Dunes · Johnson Valley OHV Area
Quick, steady and comfortable through a long day of curves, with a 5.3 gal tank for real distance. You give up cruise control and an adjustable screen unless you option and build for it.
Made for Black Hills · Blue Ridge Parkway · Cherohala Skyway
It will cover the big park routes and carry the gear, but it stays a lean, sharp ADV rather than a plush two-up sofa. Loaded touring means building the bike out yourself first.
Made for Beartooth Highway · Blue Ridge Parkway · Going-to-the-Sun Road

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this KTM 790 Adventure. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
