I know one chopper guy that still use his open helmet from 1969

I have also seen the helmet replacement guidelines. A little bit too often.
If helmet is made of polycarbonate plastic, maybe yes. Fiber glass, carbon fiber and similar no.
My blue-white Schuberth C3 PRO with good color match to my K6 I bought to Christmas 2014, first season 2015 has still good white foam, not brittle and feels still fresh.
As made for my box shaped head.
A new Schuberth C5 cost around $800-1000US.
I have seen helmets on sale with graphics of 2-3 years old models.
I started a thread about this a year ago.
It ended up in good comments and 2 links.
- Tests if old helmets are still ok.
- Youtube video about the helmet's vital parts.
After that I relaxed. 10 years more
