2025 KTM 390 Adventure R

We have to say it - the KTM 390 ADVENTURE R is the most off-road capable middleweight adventure bike in its segment. Yes, it's a bold claim, but with a 399cc powerplant, true rally-inspired design, 230 mm adjustable suspension, and a 21/18"" wheel split, this new addition to the KTM R stable simply rewrites the rulebook.

Engine

Boasting the latest generation in LC4c engines, the KTM 390 ADVENTURE range muscles up with 399 cc, more power, smoother acceleration, and lighter overall weight than before. Drawing from years of experience in the small engine game, the KTM 390 ADVENTURE R also features an improved gearbox and an optimized cylinder head.

Fuel tank

What's an adventure without fuel range? The KTM 390 ADVENTURE R boasts a 3.69-gallon (14-liter) fuel capacity and exceptional fuel economy, making long jaunts into the faraway outdoors easy. What's more, the fuel tank represents a central element of the design and engineering, offering excellent ergonomics for riders of all sizes without sacrificing off-road handling.

Smart Rider Tech

The KTM 390 ADVENTURE R confidently carves up any road surface, thanks to its low center of gravity, nimble handling, and 21" front wheel. This also means you can grab a handful of brakes with total confidence thanks to high-tech Cornering MTC, Cornering ABS, and Offroad ABS. These allow riders to apply more power mid-corner on the tarmac and get the most out of the brakes.

Cruise Control

Whether you're settled into a long homeward journey along the motorway or stood up on the pegs crushing a rough goat path, the KTM 390 ADVENTURE R seat is ready to ride along. It is narrow enough to allow for easy knee movement when standing on the pegs and comfortable enough when sitting down; it makes for the ideal perch for adventure riders.
