Engine Displacement: 398.7 cc
The 2026 range graduates to the new 399 cc LC4c (compact) engine. This liquid-cooled, single-cylinder unit is lighter than the previous 373cc engine and is optimized for higher thermal efficiency and a broader spread of torque.
Max Power: 45 - 46 PS
Outputting up to 46 PS, the 390 Adventure remains the most powerful single-cylinder ADV in its segment. The power delivery has been refined to be smoother at low speeds while maintaining its signature "Ready to Race" top-end punch.
Max Torque: 39 Nm
Torque is bumped to 39 Nm. A key highlight for Nepali riders is the 22° climbing ability, the steepest in its class, allowing it to conquer high-altitude passes like Thorong La with ease.
