Dumbledore and Sirius Black.

Dumbledore: "Hagrid. At last. And where did you get that motorcycle?" Hagrid: "Borrowed it, Professor Dumbledore, sir. Young Sirius Black lent it to me.

In the Harry Potter books and film series Sirius Black's motorcycle is an ordinary-looking motorcycle with a sidecar, though this is deceiving: it is much larger than its average counterpart, emits a very loud roar, and has the ability to fly. It is large enough to accommodate Hagrid, a half-giant, and is still able to carry an ordinary-size person in the sidecar, and can go fast enough to compete in speed with a broomstick.
