Thanks. yes it worked for me when I started riding years ago with a Shoei that time.

I took that Shoei to PFS and their Japanese tech just chased me out, really, chased me out. Not complaining here, just describing what happened. It was during Sepang booth, and it was crowded, and they were worked hard. They won't even look at it, not gonna touch it. I told them just add a few of those sticker pads or freshen up the cheekpad, just 'no, no, no, not fitting for this helmet'...

Shoei PFS has a downside.
Additional foam added actually blocks airflow.
My head was more sweaty after PFS.

Bought a standard headliner and put it back in, took the PFS'ed headliner out.

Now much less sweat and can feel air flow through my skull.

Just quietly lurking around :lol2:
Oh I see

When I asked them about how to clean those inners, they say just soak it in a pail, lightly hand squeeze and hang dry. Don't use a washing machine.

Now I know why 
I have also heard HJC salesman told me their customers that has both HJC and Shoei, Shoei's inner will self destruct even if helmet is left there on the shelf long enough. Ahbutthen, when I hear such comment from a competitor brand, I always take it with plenty of salt.

Having owned both brand before, I do observed HJC's inner foam is of slightly higher density type than Shoei.

Old model helmet they downright reject.
