1971 EJ Potter Chevrolet V8 Widowmaker 7 is all set to go under the hammer at the upcoming Bonhams Las Vegas Auction.
In 1960s, some of the motorcycle drag racers, EJ Potter in this case, borrowed technology and even engines from cars. Strange, isn’t it?
Bonham’s description says that Potter, who lived in central Michigan town of Ithaca, competed on dirt tracks. In 1960, he decided to fulfil his dream of placing a Chevy V8 engine into a motorcycle.
A 283 cubic-inch carburetted from Chevrolet was the first engine Potter used. Only a chain and sprockets connected the transmission to the engine. Steel was used to make the frame and the engine was used as a stress member.
The frame was made out steel and used the engine as a stress member. Potter built many V8-powered machines.The Widowmaker 7 which is going to hit the auction block is the one powered by a small-block 350 cubic inches V8 with Crane gear-driven roller cam and rockers. It also sports Brodix aluminum heads, 12.5:1 forged pistons and a 1960s Vertex Len Hughes-built magneto along with a Kinsler-rebuilt Hilborn fuel injection.
The motorcycle delivers 500 ho and it broke the record back in 1973. The Guinness Book of World Records has confirmed it as the world’s fastest motorcycle back in the day. The bike also held three AHRA world records going 8.68 @ 172 mph.
In 1999, Potter was the last to ride this Widowmaker. He died in 2012 at 71 after battling Alzheimer’s.
The bike is expected to fetch between $65,000 to $85,000.
