KTM North America is recalling certain 2022 through 2024 390 Adventures, as well as 2022-2023 Husqvarna Vitpilen 401s and Svartpilen 401s due to a potential issue with an e-throttle module on certain bikes.
On affected bikes, the e-throttle module could allow moisture inside. This, in turn, could cause a fault that the engine control unit (ECU) will then modulate by setting the engine to operate at idle speed until you switch the ignition off. From the description of the behavior in the recall notice, it appears that it may behave properly after switching the ignition back on again, but only until the same fault is detected and the ECU tells the engine to only operate at idle speed again.
You probably don't need me to tell you this, but if your bike's throttle isn't behaving as expected, it can pose a danger to the rider and their bike, and increase the risk of a crash and/or injury. For these reasons, KTM North America is recalling as many as 9,070 motorcycles, which it says represents around 1.6 percent of the population.
