Bosozoku Scooters

Bosozoku (暴走族 = lit, violent running tribe) according to Wikipedia:

Bosu Mag

"is also applied to motorcycle subculture with an interest in motorcycle customizing, often illegal, and making noise by removing the mufflers on their vehicles so that more noise is produced. These bōsōzoku groups also engage in dangerous or reckless driving, such as weaving in traffic, not wearing motorcycle helmets, and running red lights"

 I've seen many of these biker gangs around my area.  You definitely can hear them coming.  Their bikes are "supaa urasai" (really loud).  I always thought they were Japan's version of the obnoxious Harleys.  In any case, their bikes are fully customized looking like something out of a Karmen Rider V3 episode:

But the "Bosozoku" culture doesn't stop at motorcycles.  Even cars are "bosozoku"-ed up:

Mo Urasai!!

But more importantly scooters are "bosozoku"-ed too:
