Not a bike helmet, but Rosberg’s 2016 Schuberth is awesome. https://www.cmhelmets.com/product/nico-rosberg-2016-f1-replica-helmet-full-size/
I couldn't believe the Marquez one was real. I would be wrong... http://championhelmets.blogspot.com/2013/10/marc-marquez-motegi-helmet-japan-2013.html
Can't say enough of Shoei X-12 Luthi (2010) And now the Shoei X-14 Yanagawa5 (2019) --> green helmet and the Scott Russell Shoei X-8 Air back in... sheeeet can't remember lol Too far back !
A buddy of mine still has his old Pascal Picotte jester helmet. It's cool. The Harada one is nice, too.
Checa's WSBK Xlite World globe helmet. The Blue or the Black, I prefer the blue one. Checa sucks, but the helmet was badass.
I've had many helmets since the mid-'80s, very few of them were solids. I'm still drawn to the classics, even if they've been updated.
