What Makes a Motorcycle Helmet Safe? (Might Not Be What You Think)

Описание: What actually makes a motorcycle helmet safe? In this video, I break down the real-world crash physics most riders never hear about: why helmet shape matters for energy dispersion, why a hard shell can be more likely to slide over obstacles instead of catching, and why a smooth shell matters for the same reason.

We’ll also talk about why head shape matching is a big deal, and why brands like Arai and Shoei have historically offered different internal shapes depending on region. A helmet that “kind of fits” but still leaves gaps that reduce contact area is not ideal.

If you’re shopping for a new lid and you want to understand safety beyond marketing hype, this is the guide.

Note: This video is not a fitment guide. I don’t recommend buying a helmet you haven’t been properly fitted for
