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.
The 2025 KTM 390 ADVENTURE R is available in 2 variants – International and Indian. The Indian version comes with lower suspension travel and ground clearance and sold in India and potentially other Asian countries.
