Back in the late seventies when I was wearing open faced helmets, my brother in law was wearing a full face helmet.
He had an accident when he had a front tyre go flat. He landed face first in the road, the front of the helmet was all chewed up but it did it's job and he was un marked. My helmet went in the bin the next day. I wouldn't ride a bike without a full face helmet. When parts of you and the road meet there is only one winner.
True story. In the late 70’s all of my crowd wore full faces. Wouldn’t be seen dead in one of those crappy old opens. Except for 1 friend. Then he bought a big Suzi and all the kit to suit, including new Bell full face.
A couple of months later, he was run off the road, hit a tree whilst airborne over a bank, and copped a tree branch straight through his visor. Massive damage, top jaw broken away from skull, etc. recovered, thankfully, but a long road back.
We’d ribbed him for ages about his open face helmet, then this!
