I'm looking into getting a street bike helmet now but I'm not sure what size my noggin would be. Lacking a tape measure at my disposal at this very moment I turned to looking at my dirtbike helmet. It says it's a size 4. Does anyone know of any charts or know the converion I could do to find out just how big my dome is is from that dirtbike helmet size?
I wish I didn't have to get a street helmet but I'd look like a goof wearing a dirtbike helmet so I guess I would just keep it as a secondary for dirt and maybe for a passenger.
