How do you spell a motorcycle sound?

You can't really spell a motorcycle sound, as it's a sound, not a word! However, you can use onomatopoeia to represent the sound:

* Vroom

* Brrrrm

* Wroom

* Rrrroar

* Brrr-brrr

* Brrr-r-r-r-r

* Rrrrip (for a motorcycle starting)

You can also describe the sound with words:

* A deep, guttural rumble

* A high-pitched whine

* A loud, throaty roar

The best way to represent the sound depends on the specific motorcycle and the situation.
