I got it from Jr Graham powersports. I just looked and they are $40.00 cheaper than when I bought mine. http://www.jrgraham.com/jrgc/hsrun....bRRWGHoZZr_My-3x_1/HAHTpage/HS_homeAssortment
I have a shoei Hornet. I also HAD a AFX. the AFX is, in a word, cheap. It vented air a little better than the shoei, but now that it's winter something to consider is that the AFX had no covers on the vents. THe AFX is also extremely noisy compared to the shoei. I got the shoei used on craigslist for a couple hundred. It was basically new.
I also wanted to add that I bought the shoei because I had one moderate wipeout with the AFX and DESTROYED it. I ripped the visor mounts out of the shell and it could not be repaired. Today I did a somersault on the Shoei and it's fine. If it does break, you can fix most anything on it. The $55 shields are frikken ridiculous though.
On longer trips, like a couple hundred miles one way of slab, the Hornet is hard to beat, but most of the time it's a MX type and goggles.
Arai xd3 is the best dual sport helmet. If you are heading into bad mud just flip shield up put goggles on. If you crash and rip visor off be happy you are wearing a Arai and just pay cash for new visor and shield or helmet cheaper than broken skull. Comfort at high speed is great and make ride alot more relaxed.
I like the flip up helmets, I use a Nolan 102 for general use, commuting, two track. It seals well, vents ok in the summer. I don't like the second tinted visor, if you ride with the main visor up a click or two the tinted visor unless its all the way up will scratch the main visor. Real off road I use a Bell Moto 7 and goggles. Motosports had them on sale for $99. Took me three times to get a Bell that fit right, you have to have a head shaped like an ax, wide in the back and a narrow face, had to modify the cheek pieces to fit right.
