The denial came a little too quickly to be completely true. Sirius simply smirked at his friend, "Walker? Why, that's just pitiful, Moony! You'll never get anywhere quickly walking."
Sirius could practically see the wheels in Remus's brain start to turn, but he dutifully ignored the quirked eyebrow and unspoken thoughts. It was best if he didn't talk himself into a lecture, "Alright then," he gave the key a quick turn and the lock a flip before hitting the starter, making it roar to life. He grinned at Remus, reluctantly shoving the helmet on his head, pulling the strap into a secure position before getting on the bike and easing it out of where it was. He just did a quick loop around the street, not wanting to just leave Remus standing there. It made him absolutely giddy even in that short few minutes, "So, what do you think?" It was completely smooth, absolutely in perfect condition.
