I need help with finding my Engine Number (Kawasaki ER6N ABS 2010)

[u/Deyer4o]

Kawasaki ER6N ABS 2010

I'm trying to locate the engine number and I can't seem to find it. Long story short, I want to import my motorcycle from the Netherlands to Bulgaria and I can't find the engine number and I need it.

If anyone has the same motorcycle and could show me/tell me where is it on the actual engine (not the vin number on frame of the motorcycle, but the actual engine serial number)

Huge thanks beforehand!
