I have a new HJC RPHA-Max, their top of the line modular. I'm not certain that I would buy it again. It has some advantages over it's predecessor, an HJC SyMax2, but also some downsides. First, the advantages.
The ventilation is the best of any helmet I've had. Well, to be more precise, the TOP ventilation is the best. The internal visor does NOT block the ventilation whether it's up or down, a shortcoming of the SyMax2. The front/chin vent is, as with pretty much every full face/modular helmet I've worn, useless. The RPHA is a bit quieter. It is Pinlock ready and equipped. The visor will hold small gaps. Removing and installing the face shield is the easiest I've used to date.
Disadvantages:
The flip-up portion doesn't flip quite as high. This also means it doesn't rotate quite as far back, so I've smacked the chin bar into things because it projects a little farther forward (when up) than I'm used to. If you aren't coming from another modular helmet, this may not be a problem for you.
The visor creaks horribly when raised. The visor MUST be down in order to flip up the face. The locking mechanism is VERY stout, as in I have to hold the back of the helmet with one hand and slam the face down in order to engage the mech, otherwise it may take me 3 or 4 attempts to get the face to lock down.
