Even better than I expected! I figured this helmet would be OK for the price. If it was junk, "who cares? It's cheap." But I was wrong. This helmet is GREAT! It's solid but light, looks awesome in the sun (I chose Black), the padding inside is super comfortable and is diamond stitched leather or vinyl. The clearcoat on the helmet seems very durable considering I've already had a bunch of tree branches scrape against it while riding and I can't find a scratch on it anywhere. Everyone who's seen this helmet loves it! Highly recommended August 10, 2016
RT66 design is wrong The helmet is fine, but the graphics annoy me. RT66 went from Chicago to LA. It did NOT go through 3 of the states listed (Indiana, Utah and Nevada) on the helmet. And I'll ad that the Indiana Polis thing is not even a place. The state is Indiana, Indianapolis is the capitol of that state... and neither has anything to do with RT66. June 19, 2016
Very nice helmet indeed I am a 57 cm head size and this helmet fit very nice in a small size and it fits like it was tailored for me. I was a bit worried it would be to small as I have never bought a small in any helmet but the size chart worked fine. It has room for my big ears comfortably and fits my head shape just fine. No pinching in the temples or in the front or back of the head crown. The lining is nice quality and well done. It is so light I was surprised when I picked up the delivery box. The route 66 graphics are outstanding. The chin strap is a little rough on the edges and short mainly because the D rigs are very thick and a little sharp on the edges like they were stamped out a little to thick and not finished enough before plating. Thickest D-rings I have ever seen. So this makes threading the strap a little difficult and using the snap retainer a little hard to reach. But the buckle works ok and with some patience and time will probably improve with use. Or add a quick connect helmet snap and this would lengthen the strap a bit more and improve the strap function some. If vents were added and the chinstrap improved this would be the best open face helmet for the money. May 9, 2016
AFX Lines and R66 and buckle upgrade I bought the Rout 66 and the Lines Orange and White helmets. I mentioned in my review of the R66 that the D - rings were not made to be easy to use and they shortened the straps to much. I bought RideWear quick release buckles and removed the D rings with a small heavy duty wire cutter ( They cut easy - Cut carefully near the strap and slide the scrap out of the loop ) and installed the buckles very easly. They work great ! The straps are now long enough to work very well with the buckle and the retainer and provide much more adjustment of the fit. Makes all the difference in the function of this nice helmet. May 27, 2016
I like it! I've had good luck with AFX medium size full face helmets in the past, so I decided to give the 3/4 a try. I fits me well, a bit tight in the ears but they will wear in. You get the a bit of a bubble head look, but that's with all DOT helmets. My medium AFX 3/4 is a much smaller profile than my wife's small size 3/4 from another well known manufacture. I put on a biltwell bubble shield and that takes care of the bubble head and any lifting at speed. I went with a flat grey one, can't really mess that up. Overall quality is what you expect in this price range. April 22, 2016
Great helmet I would recommend this helmet to anyone!!! Great helmet I would recommend this helmet to anyone!!! October 6, 2014
Overall, A+ Many compliments on this new lid! Very light! Follow the sizing chart. I am glad I went with the AFX!!! September 22, 2014
Best fitting 3/4 from what Ive tried. I, like most of you, tried on as many of the 3/4 helmets as I could and read all the reviews and the forums. Tried the Rockhard which everyone said was the least bobble looking. Returned it because it looked bobbly. Found the AFX at a local shop and tried it on and loved it. Its not as high on top as the others so it has a better profile. Helmets gorgeous inside and out and I took a chance on the gold because the online photos are terrible. This things beautiful. BEWARE- I usually wear an XXL in most helmets. On this one I wear a Large and my head measures 24". Mind the size chart. July 30, 2014
