A Florida man has topped 300 mph on a conventional motorcycle -   and is also nuts!

He hit a speed of 311.945 mph Sunday at and old Air Force Base in Maine.

He ran  a turbocharged 1299cc Suzuki is the fastest speed obtained on a conventional motorcycle.

Faster speeds have been recorded for so-called streamliner motorcycles, in which drivers ride inside an enclosed missile-looking device on wheels but this was an actual "street bike"

He held the previous speed record of 278.6 mph, set last October in Texas.

I'm sorry, but you have to be just a little bit crazy to go that fast in anything, let alone a motocycle!
