Will it fit?

When deciding which Metropolis version to buy (did you know there were 2? There’s the original 2013 model and a 2015-facelift), my major concern was whether a modular helmet (HJC IS-MAX II in my case) fit inside the rear compartment.

And yes, it does fit. So does Schuberth C3, Nolan 104 and some other pretty big helmets. One secret thou: You have enter the helm visor-first, otherwise it might not fit!
But bad news for the 2013 model (prior to 2015): I have no idea, what helmet would fit in there. I’ve tried every SMALL helmet I could (jethelmets even), nothing fits.

So if the owners of the 2013 model could let me know in the comments, which helmets fit – I’ll update the info.
