Arai RX-Q Comfort Liner 5 5 12 12
OEM replacement Nothing much to say about this comfort liner: it fits as it should, will break-in as it should, and is new so doesn't smell like my sweaty head. I've replaced the comfort liner, cheek pads, and neck roll to freshen-up the helmet; after four years of wear the helemt was a bit stinky. October 26, 2015
It was comfy and. My arai rx-q helmet was a little big once it broke in so I ordered the 12 mm liner and it worked great it was just what it needed to b nice and fitting so it wouldn't move when riding. I usuAly wear shoei helmets in a medium and I was happy w them but after I got the arai from revzilla I won't wear another helmet but the arai. November 2, 2014
Drop in replacement. One advantage of buying a Arai helmet is that you can buy different thicknesses of liners for the same shell. After a while my size large liner did not fit as snugly as I wanted. So I just bought the medium liner, dropped it in and now my helmet fits as it should. October 13, 2014
makes helmet fit , it's a liner went from the 7mm to 10mm. Makes helmet fit perfect. But like all Arai liners for RX-Q. If you do not have a full head of hair. The forehead pad stitching at "liner frame" can rub you at the forehead. I just dented the EPS to eliminate this. But Arai should rethink this liner design. Thus I gave the comfort... average w/o the EPS denting that is required. Thanks for sending it so fast. July 29, 2014
May be just what you need. 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. January 13, 2014
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. November 22, 2013
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. October 15, 2012
Arai Liner I replaced this with my stock liner... what can zI say but comfortable and perfect fit!!!! September 3, 2012
