I recommend finding a list of helmets by head shape. Most heads are narrowed down into 3-4 shapes if I remember correctly. I know I have a round Or oval head. I searched for that type, narrowed down to the AGV K3 SV and one Shoei offering. Made a trip to cycle gear to confirm that the AgV was a perfect fit. Best it of every lid in the store. The list helped me a ton. I think this is the one I used. https://www.webbikeworld.com/motorcy...nternal-shape/. Hope this helps. Looks like the list is going on 2 years old now, can probably still use as a reference or find a newer one. Some companies offer adjustable / replaceable pads, where others aren’t even removable.
