2025 KTM 390 Adventure R

SUPREMELY CAPABLE
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.
