"Bōsōzoku" are known to modify their motorcycles in peculiar and showy ways, which are called Kaizōsha (改造車,"Modified Vehicles"). The general style of "bōsōzoku" bike modification appears to combine elements of an American chopper bike and a British café racer. Examples of modifications that are taken from these styles are raised handle bars like those on a chopper or over-sized fairings like those found on café racers (though "bōsōzoku" usually fit them much higher on the bike than their original position, and angled upwards at the front).
