our eldest had a van pull out in front of him, the result has left him paralysed, he wrote to Shoei asking if they wanted his helmet for examination or as an example with a big crack in it , all he had was a slight headache, amongst the broken vertebrae, they replied, they didn't need it as they know their product is good. he still has it until the legal investigation is over . I would doubt a helmet a fifth of the cost would have given him as much protection
