Brazil's largest biker gang is a rather youthful bunch -- having been formed just 20 years ago -- but the gang's influence seems to be spreading, as chapters have popped up not only across Brazil, but also in neighboring Argentina. Other chapters -- of largely homogeneous, Brazilian makeup -- are purported to have formed in Japan, the U.S. and Spain as well. In case your Portuguese is rusty, "abutre" means "vulture" in English, thus they're also known as Vultures MC.
PS : Sorry for those not in the top 10 chart, try harder...maybe next year you might see your MC in the chart...
