If you dare! EJ Potter was fearless with the 500 HP 1971 Widowmaker 7 between his legs. It will be difficult to give this baby a test ride. The Widowmaker His bike recently went up for auction at the 2017 Las Vegas Motorcycle Auction. Before the auction, the Widowmaker 7 had not been ridden since 1999, when Potter himself took it for its last run.
The Widowmaker 7 is powered by a Chevrolet small-block 350cid V8 engine that can drum up 500hp, a feature Potter used to help him achieve speeds of 170+MPH on the track. The bike also has Crane gear-driven roller cam and rockers, Brodix aluminum heads, 12.5:1 forged pistons, and a 1960s Vertex Len Hughes-built magneto, and Kinsler-rebuilt Hilborn fuel injection. In 1973, Guinness awarded the Widowmaker 7 the title of World’s Fastest Motorcycle. More Info
