E.J. Potter’s self-built drag bike is powered by a 350 cid (5,735 cc) 500 horsepower V8. It’s a perfect example of form and function.
The bike was quick:
In 1973 the Widowmaker 7 was confirmed as the fastest motorcycle on Earth by Guinness Book of World Records, recording an 8.68-second 1/4 mile run at 172 mph.
Things have certainly changed. The video below shows a stock 999 cc – except for swing-arm and rear tyre – motorcycle running the 1/4 mile in 8.44 seconds in 2010.
Even straight off the showroom floor, one litre motorcycles can, with some practice, run the 1/4 mile in 10 seconds flat. With minor modifications, like a free flowing exhaust, times in the mid nines are easily achievable. It’s nuts.
