In terms of how to go about doing it, the easiest way is probably use a CN with a source that reflects your desired vehicle size--that's especially useful if you're chasing huge Final Fantasy-style rides or something atypical, but also helps with complex posing. The harder way would probably be gradually adjusting your aspect ratio (as with my earlier gen) until it looks correct. You can add "large motorcycle" as a prompt, though unsurprisingly "small motorcycle" as a negative seems useless.
