I don't have to be an engineer to know that thing took a bigger fall than what it is designed to withstand.
But hey, lets blame the manufacturer. You should sue too like everyone else does so that prices can inflate even higher. With enough litigation you might even be able to get them to put bigger cages, slow them down even more, put airbags, abs brakes, collision mitigation, stability control, traction control, and make you sign a waver to buy one. Oh heck, lets just ban all motorized vehicles, because for every machine out there, there is an idiot that can hurt himself on it, LOL
