Clearance AC-12 a done deal

June 18, 2011

It was time to replace my AC-10, so I was casually browsing the web and saw Dennis Kirk's clearance deal on AC-12 El Diablos. I clicked. The helmet fits my oval-shaped head very well. I have trouble with fit in a variety of brands, and HJC's head-form seems to match mine quite well. The shield seals excellently, as is normal with HJCs, and is a 'snap' to remove and re-install. The textured graphics (peculiar to the El Diablo) took a bit of getting used to, but I'm good with them now. The interior of the helmet is plush and easily removable for cleaning. Overall, this was a killer deal on a high grade, highly rated helmet. Well done, DK!

I would recommend this item to a friend.

An absolute steal!

February 14, 2011

Got this on closeout. Fits true to size, nice and snug for my XL head. Note I also have a Shoei that I bought in XL, but had to buy bigger cheek pads for to make fit. The HJC XL is obviously a better fit for my head type--ovalish. Features for $ on this helmet is great. That said, I've only been able to wear it around the house. I did fit a blue-tooth comm unit (unit on outside and speakers & thin boom-style mic in the helmet), which is the reason I was looking for a second helmet to begin with. The AC-12 allowed easy tucking of the wires and thin speakers do not contact my ears. Very happy with my purchase.

I would recommend this item to a friend.

Good purchase

December 1, 2010

Helmet fits nice has good air flow used this the other morning in pooring rain, worked out pretty good.Only disapointment is their is no additional pading under the chin area which is great for warmer weather at least down to 40.Not sure how it wil work out for the days when it drops below 30.Neverthess less it is a comfortable fit and was a great bang for the buck

I would recommend this item to a friend.
