I'm looking to move from my Arai XD to my first modular helmet and don't really want to break the bank based on it being my first. So was considering the Nolan N90. My XD is a small, but haven't taken a tape measure to my head as yet.
I use a Cardo Scala Q2 on my XD. Would this be able to fit on the Nolan and would you also suggest a small?
