It didn't sort out my problem of having a helmet that was just too large for me but it's a great product if you need to adjust the fit slightly. Arai makes great products and I'm loving my helmet.

Fine tuning you're ARAI
I bought this liner to fine tune my RX-Q. My head measured right around 57cm, using the charts, I purchased a Medium. It fit like a charm during the break in period, but started feeling a little loose (loose as in not race fit, I prefer race fit). Purchasing a 15mm liner and cheek pads gave that extra dialed in fit that made the RX-Q a lot more customized if you will. I highly recommend a thicker liner if you want a tighter fit.

Just as described
The RX-Q fit my head a little looser than the same sized Vector. This tightened it up perfectly. I went to the 12mm. Terribly easy to remove and install. Makes me love the helmet even more with this level of easy modification.

Easy to replace
Super easy to replace the liner in the RX-Q, not quite as plush as the stock 7mm but it gives me a bit more space and that's what I needed.

Comfort liners for a custom fit
Arai offers various comfort liners for each helmet size. These liners allow you to have a little more room if tight, or snug up the helmet a little if loose. This option allows for a much more comfortable fit.

The ability to drop different thickness liners into this helmet made it seem like it was custom made. Great job Arai! My RX-Q is perfect now.

J S: my III- 7mm liner RX-Q was slightly loose. 10mm next step upJul 7, 2014
Janpatrick B: I just needed a new replacement for my liner.Mar 2, 2014
Stephen H: XL RX-Q had just a little wiggle but L was way too small. Hopefully this makes up the difference. We'll see.Aug 28, 2013
Stephany M: I bought my RX-Q helmet in 2010. After 3 years of commuting and weekend touring in the desert heat, the helmet's liner has compacted. The helmet is now looser than I'd like it to be. A replacement liner should help resolve this situation and make my helmet fit like it did right out of the box.Aug 21, 2013
Christopher O: I wanted to make my MD RX-Q a bit more snug. I called CS earlier this morning, forgot the Zilla's name whom I spoke with, but he was very informative about the product and clarified which liner would be better for me. TeamZilla FTW!!!!Aug 20, 2013
A shopper asked:i have the Medium sized RXQ with a (III) 15mm head liner in it already, and it just after about 5minutes of wearing it, it gives me a headache, (it feels as if just behind my temple is being squeezed too much) what size should i go down to? the 12mm, 10mm or 7mm?
Robk1300s:Depends on how much squeeze you're experiencing. I'm sure you know that a helmet should be snug, but not give you a headache or feel like your head is being pinched like a zit. But too big won't protect you like it should. I would first check to make sure the helmet is the correct shape for your head. Many riders chose a helmet based on the graphics. If you haven't done so already, go to a local shop(s) and try on various helmets to see which one fits best. I used to wear Shoei, but found them noisy and not a good fit for my head. I find The Arai RX-Q to be a good fit for my head. It's the most important piece of equipment you have, make sure it's going to do it's job.Nov 7, 2011
AliB:If that much pressure is on your temples, you should go down to the 10mm at least. It's difficult to make a recommendation without seeing you in the helmet or without measurements, but I think the 10mm is the best place to start.Oct 25, 2011
