Is AHR helmet DOT certified? Is DOT helmet good?

Yes, all our AHR helmets are DOT certified. As shown in the listing photos, each helmet has a small DOT sticker on the back. Some new riders may have heard of the DOT certification, but they may not understand why it is important, so we have provided an explanation below.
What is DOT?
DOT stands for the Department of Transportation. This organization set Federal Motor Vehicle Safety Standard (FMVSS) 218 for motorcycle helmets. All helmets sold for use by motorcyclists in the United States are required to meet this standard. Helmets that meet the requirements of FMVSS 218 are considered 'DOT certified' and are given a DOT sticker. However, the Department of Transportation doesn't test the helmets directly. Instead, the DOT holds the helmet manufacturers responsible for testing their own helmets and adjusting to meet the standards. What to do to meet FMVSS 218? A helmet needs to pass 3 tests to meet FMVSS 218. First is the impact attenuation test. It includes dropping the helmet on different impact anvil (flat anvil and cylindrical penetrator anvil) from a pre-set height. It simulates a crash scenario, and the impact is measured using scientific tools under two separate crash tests. Second is the penetration test. The helmet is fixed to a base, then a sharp striker is dropped on the outer surface of the helmet. The test striker must not penetrate the helmet, otherwise it will not pass the test. Third is the retention strap test. For this test, the helmet retention straps are placed under a load in tension. The test starts with a load of 50lbs for 30 seconds. The load is then increased to 300lbs for 120 seconds. The strap test ensures it can hold the helmet in place in case of an accidentWhat does a DOT sticker look like? The DOT sticker contains the following wording and information: manufacturer and/or brand, DOT, FMVSS No. 218, CERTIFIEDAlthough the DOT certification is often considered as the most basic standard, it does certify that the helmet meets important safety standards. We recommend being sure that any helmets you purchase have this certification.

Helmet: How do you measure head size before choosing a helmet?

A tailor's tape is the best tool for measuring your head for a helmet. Wrap the tape around the thickest part of your head. For most people, this will be right above your ears, approximately half an inch above your eyebrows. Measure your head circumference. Please refer head circumference table below to choosing a right size helmet.

AHR helmet guide: D-ring vs Quick Release buckle, which is better?

Currently there are 2 types of helmet chin straps on the market. One is the D-ring strap, and the other is the Quick release buckle strap. There is no data to indicate which is better/safer, so you can determine which is better for you.
What is Quick release buckle strap?
The quick release buckle strap consists of two parts, it has a red buckle with a tab on one side and a black plastic ratchet strap on another side. You just need to insert the plastic ratchet into the buckle, and it will auto-lock. Then when you want to loosen the strap, just pull the red tab.
Pros:
(1) The quick release buckle is a easier to use and can be used with one hand. Quick release buckles are more common and convenient for casual motorcycle riding.
Cons:
(1) It is not easy to use with a helmet lock since there is no ring. Instead, you can use a coiled cable lock and run it through the face opening of the helmet.
What is D-ring strap?
D-ring strap consists of two metal D-rings on one side of the strap and a simple strap on the other side. When you are securing your chin strap, you need to pass the strap through both D-rings, then around and through the center of the first D-ring and pull it tight to secure. The pros and cons of D ring strap are below:
Pros:
(1) It works better with a helmet lock.
(2) A D-ring helmet chin strap is considered the industry standard for helmets used in motorcycle racing.
Cons:
(1) A D-ring strap can be difficult to use, especially when you are wearing a gloves or if it is your first time using the strap.
(2) You need to secure/loosen it with two hands.
