Great Dual Sport Helmet For The Money!!

First off, Motosport is absolutely excellent. I ordered this helmet on a Tuesday, and it was at my door step on Thursday. I checked out many other websites that sell gear/parts/etc... and I am so glad I had chosen Motosport. Not only do they have a huge selections, the pricing is very competitive, and their shipping is crazy fast.

As far as the helmet, you can not go wrong for the price. I have owned many helmets in the past, and this AFX is solid, looks great, and its not to heavy (although its a big helmet).

If you are on the fence on what helmet to purchase that is in this price range, do your self a favor and buy an AFX.

Cool Helmet, dirtbike look with streetbike comfort

When you get down to it, this is just a full faced helmet with a visor on the top and a pointy chin. It does pull off the dirtbike helmet look which is apparently important for us that ride dirtbikes on the street. It is comfortable and quiet and blocks the draft like any streetbike helmet. The shield flips up high enough that I don't notice it. I was hoping I would be able to use it with goggles but that requires removing the shield. The visor does grab in the wind but nowhere near as bad as my MX helmet. The only real beef I have with it is the chin strap is ludicrously long. There is a neat ratchet device to cinch it tight but it is at the end of a very long strap. I had to shorten the strap as far as it would go to get purchase on the ratcheting portion.

AFX tends to run true to size. If you are properly fitted into a XL, I would suggest ordering the AFX in a XL as well.

1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch above your eye brows. When done properly, you will have measured the largest part of your head.

2. Check your measurement with the helmet sizing chart and select the closest size. As the helmet may not always meet your head size exactly, and your head measurement may fall between two sizes, first try the smaller size.


1. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug. If the helmet is not tight, it is too big for you. New helmets will break in and loosen slightly over time.

2. Once the helmet is on:

  • Check that the helmet inner lining fits snugly all around your head.
  • Check that the top pad presses on the top of your head.
  • Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
  • Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
  • Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
