Back in the day, my friend was doing "speed run's " on a lake , flogging a kitted up RD350 Yammy,,,,,80mph with studded tyres,,,,,open water ahead,,,,,laid it down,,,,,right into the drink was only 4ft of water and of course "black" mud,,dragged it up and out,,,turned into frozen black mud, ,,no real damage done,,,funny thing he now has a KTM to flog the ice with,,,,,,,
