I'm going to Bolivia to watch the world's fastest motorcycle try and break it's own world record, and hopefully put it past 400 mph! Six years ago, it set the record at 376 mph, but on their final qualifying run, they topped out at over 394 mph. So they're pretty close already. To go even faster, they wanted a longer track, and less air resistance would be nice too. At Salar de Uyuni, Bolivia, they may have a 10 mile run up, (Bonneville was only 6 miles) and they'll be running at 12,000 feet elevation, (Bonneville 4,200').
