Some of you have watched the movie 'Snakes On A Plane' I'm sure. Well, this is sort of like that only there is only one snake a motorcycle and it's not a movie.
Watch the video courtesy of a helmet cam. The video has subtitles because you can hardly hear what their saying. keep your eyes on the handle bars.
