Immediate ECU update issued after rare engine-stall findings

KTM has issued an immediate software update for several 390-series models after internal testing revealed a rare condition that could cause engines to stall at low rpm. The update affects the KTM 390 Duke (MY 2024–2026) and KTM 390 Enduro R, SMC R, Adventure R, and Adventure X (MY 2025–2026).

The full KTM release reads:

“Extensive quality testing revealed a condition that, in rare cases, could cause the engine to stall at low rpms. While only a limited number of cases have been observed, KTM is taking decisive action to eliminate any potential risk and uphold the highest standards of performance and safety.

An update to the engine control unit (ECU) software will be applied to all affected motorcycles. This update significantly reduces the risk of engine stalling, particularly at low speeds or during deceleration, while also improving rideability with improved low-end torque and increased engine stability.”

Owners of affected bikes will be notified by letter and are encouraged to book in with an authorised KTM dealer for the complimentary update. The company stresses that the software flash will be performed free of charge and exclusively through its authorised dealer network. Riders can confirm whether their motorcycle is included and find a dealer list via the “Service” section of KTM’s official website.
