In this brief guide, we will go through the steps to check the engine oil level of the KTM Duke 390 motorcycle. First, position the motorcycle upright and ensure the engine has not been running for the last five minutes; locate the sight glass on the lower right of the engine casing, which indicates the amount of engine oil present inside, as shown in the video. The engine oil level should always be at the maximum mark (this type of engine has a capacity of about 1.6 litres); if the level is at the minimum, topping up will be necessary.
