"How to say motorcycle in English" is the translation of "摩托车用英语怎么说".
Motorcycles are typically referred to as "bikes" or "motorcycles" in English. If you're referring to the vehicle itself, it's called a "motorcycle". If you're referring to the two-wheeled vehicle that carries a rider, it's called a "motorbike" or "bike".
If you want to ask how to ride a motorcycle, you can say "How do I ride a motorcycle?".
If you want to ask what kind of motorcycle someone has, you can say "What kind of motorcycle does he have?".
I hope this helps! Let me know if you have any other questions.
