I had a basic L HJC helmet with my old bike and upgraded to a M Shoei RF-1100 when I bought the Duc. I then sold the HJC because it was too big for anyone Id take for a ride. Im trying to figure out what helmet to get for a passenger that will work for most heads...And...if someone has one they are looking to part with even better! Im thinking probably a Medium full face HJC or Bell...but I really dont know. Thoughts?
I have a M HJC that I keep for passengers. It's a little big for some, a little snug for others, but so far haven't had an issue where it wasn't even close enough for someone to use for a fun blast around town every now and then. If I had someone who was going to be a fairly frequent passenger (i.e. a g/f) I'd take her to get sized for her own helmet.
