It's called Bosozoku styling, and there's nothing quite like it in the world. Just look at those big fender flares and those insane-looking exhausts. There's also Grachan style and, again, it's a purely Japanese thing. Grachan refers to the 1970s and 80s era Grand Championships on Fuji Speedway while Bosozoku is the name given to motorcycle clubs and gangs. These types of Japanese tuning are pretty much a love it or hate it sort of thing, but without a doubt some of the results are pretty insane.
