Street Lethal is the first studio album by heavy metal band Racer X, released on January 1, 1986 through Shrapnel Records. The instrumental track "Y.R.O." stands for "Yngwie Rip-Off", as it bears similarities to "Black Star" by guitarist Yngwie Malmsteen (from his 1984 album Rising Force), with an almost identical bassline. It later appeared in the 2009 video game Brütal Legend.
