- The recall affects KTM 390 and Husqvarna 401 models from the 2024 to 2026 model years
- ECU software update to prevent engine stalling
- Recall only affects authorized dealer networks and is free of charge
At the beginning of December 2025, KTM announced a recall for several models in the 390 series. The technically almost identical Husqvarna models with the designation “401” are also affected by this measure. All affected vehicles have the current 399 cc four-stroke single-cylinder engine with an output of 45 hp (33 kW). According to the manufacturer, under certain driving conditions, especially at low speeds or when decelerating, the engine may stall, with potentially safety-related consequences.
These models are affected
The recall covers several model years and affects the following vehicles:
- KTM 390 Duke (model years 2024 to 2026)
- KTM 390 Enduro R, SMC R, Adventure R, Adventure X (each model years 2025 to 2026)
- Husqvarna Svartpilen 401 and Vitpilen 401 (model years 2024 to 2026)
All of the motorcycles mentioned are based on the same technical platform and use the same single-cylinder engine, which requires software adjustment.
Technical background and purpose of the update
According to KTM, internal quality checks revealed that “in rare cases, the engine may stall at low speeds.” Although only a few such incidents have been documented, the manufacturer says it is responding “proactively to eliminate potential risks and ensure the highest standards of performance and safety.”
The update only affects the engine control unit (ECU) software. It is designed to significantly reduce the risk of engine stalling while improving rideability. In particular, torque in the lower rev range is increased and engine stability is improved. This can be crucial for safe handling, especially when riding slowly or in push mode.
Handling of the recall
The software update will be carried out exclusively by authorized KTM or Husqvarna dealers and is free of charge for owners. All affected customers will be notified in writing. In addition, it is possible to check whether your own vehicle is affected via the official websites of both brands.
To do so, they must enter their 17-digit vehicle identification number (VIN) and delivery certificate in the “Service” section. This applies in particular to those who have not yet received written notification.
Background: Second recall within a short period of time
The current measure is already the second recall within a few weeks. At the end of November 2025, KTM had previously recalled several models due to possible leaks in the fuel cap seal, including some variants of the Duke series. The 390 models now affected are thus once again the focus of a safety-related recall campaign.
