[It comes out grumbled, purposefully left too loud to be properly under his breath. That's because he's not actually upset, at all.
He shifts the bike's weight onto its tyres. The movement changes the pitch of the idling engine. So does switching it into first gear--louder, and louder still when he raises himself up off the bike a little and kicks it to a proper start. A few cursory revs of the engine and--without warning--he kicks off. The bike jumps forward with a growl; the tyres squeak against the floor, and then they're off, streaking down the length of the shuttlebay.
If you didn't know the motorbike was invented, fixed into being by Sirius' mind alone--well, then, you wouldn't know that the motorbike is sheer invention. It's very real, to all actual intents and purposes--including its speed. Not as fast as a more modern bike, but fast when you've not been on anything quicker than a hovercart in months and months, and Sirius laughs, delighted. The sound is mostly lost under the engine.]
