Nocturnal motorbikes

There is something about the neighbourhood we live in: although generally very quiet, being in a quiet little town and out of the center, but it has its share of nocturnal activities. Among them, we can often hear motorbikes racing (or it sounds like they are racing anyway). I imagine them fancy high tech Japanese, but maybe it is because of a recent experience. I wonder sometimes if there is not nearby a gathering point or daredevils.
