I don?t believe it, I?ve literally just tried one the other day as had the same modular thoughts as you re touring lid [emoji6]
It?s a very nice helmet, has the modern Shoei fit which is longer front to back therefore accommodating an intermediate-oval head shape well.
I?ve purchased a Schuberth C4, for two reasons, firstly it?s a more round-oval fit which works much better with my round head shape. Secondly, I personally much prefer the SC1 intercom in the Schuberth, as it is fully integrated with no boom mike, as it?s all integrated into the EPS/liner.
That being said, choosing between the two entirely comes down to fit IMO as they are both very similar and equally very high quality helmets.
Best of luck with your deliberations [emoji4]
