KTM adapter for draining the engine oil does not stain the motorcycle

The adapter for draining the engine oil does not stain the motorcycle and the environment. Thread M 12x1,5.
Lay the motorcycle horizontally with the oil drain bolt at the top. Screw in the adapter and clamp the hose. Stand the motorcycle upright. Insert the hose into a drain container. Unscrew the oil filler cap to allow air to enter. Good luck.
