Oh, yes! It is possible, as five-time Enduro World Championship winner Ivan Cervantes demonstrates. At one point during his practice runs, Cervantes came up to a lake and decided to try something different. He decided to ride his motorcycle over a 42-meter long lake that's about 1.5 meters deep. After a few failed attempts, Cervantes managed to cross the lake while doing around 56 mph (around 90 km/h).
