2025 KTM 390 Adventure R and 2025 KTM 390 Adventure X Officially Announced

February 1, 2025 editor 2 min read

As a follow up to the prototype unveiling at EICMA 2024, the 2025 KTM 390 Adventure R and 2025 KTM 390 Adventure X have been officially announced.

Looking back to EICMA, we expected the off-road biased “R” variant but did not expect KTM to roll out an all-new road-biased model, too. The road-biased model now has the letter “X” affixed to it, instead of having no letters after the “Adventure” name.

Both are powered by the same updated 399cc LC4c single-cylinder engine, which produces 44 hp at 8,500 RPM and 39 Nm at 7,000 RPM. The engine receives a new stainless steel exhaust system which is 5 kg lighter, revised fuel injection, airbox, and cylinder head. The gearbox has been reworked and the slipper and assist clutch is standard.

Also shared are the suspension and frame. Although the latter is based on the 390 Duke, there are new subframe mounts, steering head angle, and 25mm taller handlebar. The suspension is taken from the recently launched 390 Enduro R, with WP APEX 43mm open cartridge forks paired to matching a monoshock – both of which are good for 230mm of travel.

The main differences between the “R” and “X” are a five litre larger tank on the Adventure R (now 14-litres), plus the rally inspired fairing and tower which houses a full LED lighting setup, and wheel sizes. The 2025 KTM 390 Adventure R rolls on 21/18-inch wheels, while the 2025 KTM 390 Adventure X has 19/17-inch rims.

Electronic tech includes a five-inch TFT and three ride modes (Street, Off-Road and Rain – which limits power delivery and heightens traction control (TC) intervention). Whichever of these modes is in use when the bike is turned off will remain engaged upon start up.
