When I bought my VFR the original owner threw in a XL Arai Quantum/f helmet. I could have had my pick of a few spare helmets he had but the Arai had a really nice fit. However, the chin strap was a bit frayed on the end and wouldn't snap to lock down the loose end, a minor annoyance. I called Arai Customer Service and was told it would be $30 to replace the strap. Not a big deal but it also meant I wouldn't have use of the helmet for 2-4 wks. Well, I was thinking about getting a nicer helmet anyway, the Quantum/f is nice but it doesn't have some of the newer features of today's models. I went to the local cycle shop and tried on several models including an Arai Corsair V, Shoie X-Eleven, and several others from Scorpion and Shark. Each time I put on a brand other than the Arai the helmet just didn't as nice as the Arai. So I purchased the Corsair V. So I go home unpack the new helmet and go for a ride. OMFG! The helmet is noisy as hell! Much, much louder than my old Quantum/F, I closed the vents and it helped but it only took one ride and knew this was not the helmet for me. So I returned it and kept using the Quanum/F a while longer while looking for something else. I looked at a couple other bike shops and while down in Florida on vacation I try on a Quantum 2, great fit, fewer (noisy) vents and the price was $200 cheaper. So I bought it along with a silver tinted shield. First test ride and I knew it was a much better choice for me. The helmet fit is superb, materials are first rate, and it's even quieter than my old Quantum/f. Then I checked Arai's website and saw they announced the new RX-Q. Maybe I should have waited after all.
Arai are nice helmets. If the Quantum II fits you will love it like a baby likes a blanket. I have one and it is great .. I have worn mine for was many as 8 hours with no discomfort what so ever. Enjoy it .
You have to remember that the different Models of Arai (and every other Helmet Manufacture) fit different types of heads. The Quantum Series fits rounder heads, where as the Corsair fits narrow heads. get on Arai's web site and they will show you what they are. But yes- Arai rocks hands down in quality:thumbsup:
