Also when I was buying my motorcycle gear (8 years ago) the general conses I recall is that ECE ~= DOT. Not sure what OP means regarding DOT certification.
- is nearly 50 years old without meaningful changes to reflect half a century of head injury and brain injury research
- has significantly lower standards for how much force can be transmitted through the helmet to your skull - well within values that commonly cause skull fracture
- does not have any brain injury criteria for rotational trauma
- does not have any independent random testing, and limited independent random test studies have found 50% of labeled helmets don't meet the standard
The last point is especially frightening! ECE has fixed all of these issues. Fortnine's videos on this (and the problems with Snell 2020R/2020D) are a great place to learn more.
