Why diesel engines can't be used in two wheelers?

Diesel engines can’t be used in two wheelers:
It is because diesel engines don’t use a spark plug. It uses heat of compression. It creates a flame, stress is more because of which size of the engine should be more. It obviously increases the weight of the vehicle. A diesel engine also have knocking behavior which creates more vibrations.
A diesel engine needs a fuel-injection system. These extra things need more space. Space and weight limitations are there. So a diesel engine is not advisable to be used in two wheelers.
A high compression ratio is also one of the major factoear. It means high pressure in the cylinder.
In spite of these limitations there were bikes with diesel engines.
