Sirius Black's motorbike

When Rubeus Hagrid delivered recently orphaned infant Harry Potter to Privet Drive, he arrived on a magical flying motorbike. The bike had an impressive engine, and accommodated a half-giant quite comfortably. It belonged originally to Harry's godfather, Sirius Black, who gave it to Hagrid to help transport Harry. Harry's experience of the motorbike came full circle when he left Privet Drive for the final time on the very same bike, once again ridden by Hagrid. For this final journey, the motorbike received some modifications courtesy of Arthur Weasley.
