Sirius And The Flying Motorcycle
Sounds like a new childrens book for the title.

In this thread we will discuss Sirius' motorcycle. I have always found this quite interesting and want to see what the rest of you think. We know that Sirius gave Hagrid the motorcycle to take baby Harry to the Dursley's but what we don't know is where is it now and how did he come upon such an unusual muggle artifact.
Questions to think about:
Where is it now?
How did he come upon the motorcycle?
Why he gave it to Hagrid?
Anything else you would like to add...
