I tried on the K6 and immediately hated it. There’s a reason there are so many different helmet manufacturers out there, all made for different head shapes. AGV’s do not fit mine. I’m definitely a Shoei guy. That being said I have a buddy who rides with a K6 and loves it....so yeah, lol
On fit you need to discover if you are a peanut or a bowling ball and which manufacturers best suit your skull shape. Bell and AGV are better suited to peanuts and Shoei and Arai to rounder heads. There is an element of racial profiling to it all I reckon I am Neanderthal throwback so AGV and Bells are my bag. https://billyscrashhelmets.co.uk/agvs-sports-touring-motorcycle-helmet-agv-k6-review/
