High Quality Paint

I used the sizing chart and helmet was too big. I got the right size and love it, I scuffed the helmet and I was able to buff it out without messing up the paint. It is my first helmet and it fits well, not loud at regular speed.

AGV K3 Mono helmet

I absolutely love this helmet, it looks great. I had to order one size up, but it fits perfectly. It's comfortable and reduces a lot of the wind fatigue and head jerk at highway speeds. The quality is unbelievable for the price. You get an arai or shoei quality helmet for the price of an HJC. Shipping was on time. No complaints.

Awesome looks and quality finish

Great helmet. I really like the graphics. Better than most of the "old man graphics" type helmets. I usually wear an XL but this one was a bit snug so I ordered an XXL. Fit perfect. Shipped on time. Me so Happy! My new AGV love me long time.

Amazing Lid

I bought this Helmet thinking i was getting a entry level product, boy was i surprised. The paint quality is top notch, The interior is as plush as helmets at twice the price. the vents work better than any other helmet I've owned, and for the price its remarkably quiet. I bought a large and it was too big, thanks to the one size shell i was able to order a set of medium cheek pads problem solved. The shield release makes visor changes a no tools snap. Did i mention how quiet it was. The biggest surprise with this helmet for me was the weight or lack there of, compared to helmets in the same price range nothing else even comes close.

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 and across the largest portion of the back of the 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.
