When suddenly all goes wrong & you wake up knowing something has gone wrong & sometimes wondering where you are. There is the m/c on its side, your hand tells you the engine is cold & same hand tells you the header pipe is cold ------ then you know you have been out for a while.
Examine the helmet to note it is badly damaged & that could be your head. Tends to make one think.
You are about to pick up your downed & gain a cold engine m/c & cannot even figure what day it is or where you are till you recognize something that links you with said area. Take a look at the helmet & realize it was totalled & again it could have been your head.
Still how many people riding without a helmet get that or other chances I have received thanks to crash helmets saving my life? Still it has happened to me many times in the past.
The above is relate to dirt riding incidents when practicing for comp., or possibly when just riding in the dirt & yes I have also found I was with broken limbs or bones. Tack on a few accidents on the pavement in town & on the hwy.
We are riding m/cs that are lighter then many of the bikes of the past, with far, far more horse-power, are moving at speeds well beyond even the better riders in the late 40s or 50s AND there are far more cages out there then in the past so our chances of surviving, without protection, are not as good. For in late 40s & early 50s I rode with no helmet, & just casual clothing on large m/cs of 750cc, 500cc to 1000cc & we are talking about 25hp to a 750cc flat head V-twin Harley, 32hp on most 500cc singles to vertical twins & 50hp to V-twin Vincent HRD. Something to think about I feel.
