Plastic / poly helmets bounce on impact .... ( and crack apart .. along with your neck) fiberglass / resin helmets will absorb and you take the impact like getting hit with a sledge hammer ,,, still a better option
Have to agree ,, I'm a Lifetime Member of H.O.G ( Harley Owners Group ) would never ride 10' without a helmet/gloves/jacket/jeans or chaps and boots
not to mention 2 mirrors and adequate lighting both front and rear .. as oppssed to I would venture to say no helmet,shorts,flipflops,cell phone in hand , smoking, 2-3 passengers, no mirrors and no lighting....
you can be the best rider on the road ....but ....either way you go .. even an 80year old lady driving a 3000lb car will just squash you like a bug on impact ....
