The Internet thought it was wild enough when enduro rider Matt Spears decided to try taking a Suzuki Hayabusa up Hell's Gate in Utah. Of course, probably very few people expected it to actually work the first time, but Spears wasn't keen to give up. He kept going instead, and eventually, he did the damn thing.
Is there such a thing as an inappropriate bike for a given riding situation? Maybe, but an awful lot depends on the skill of the rider doing it, too. It's a particular combination of things, and it's clearly not something that's meant for everyone. Kind of like most niches in life, you know?
Anyway, while Spears did manage to eventually get the Hayabusa through that particular obstacle, subsequent offroading eventually took its toll on the little liter bike that could. One big tumble in particular managed to practically total most of it—all except for the most important part, the engine.
