AGV K6 S Safety Rating Explained

If you've searched for the AGV K6 S's safety rating, here's the short answer: it carries genuine US DOT + ECE 22.06 and a perfect 5/5 SHARP score — which together make it one of the best-documented full-face helmets you can buy. This page explains what each of those actually means, so you can judge the data rather than just trust a number.

We don't crash-test helmets — nobody at consumer scale does. What we do is read the published certifications and independent test results and explain them honestly. Every claim here is sourced at the foot of the page. For the full buyer's picture, see our AGV K6 S review.

The certifications on the shell: DOT + ECE 22.06

The US K6 S is homologated DOT (the US legal minimum) and ECE 22.06 — the current global standard and the first to include a rotational (oblique) impact test. That matters because, as our certifications explainerlays out, many flagship helmets' US versions carry DOT or Snell rather than the ECE 22.06 their European reviews describe. The K6 S is one where the US unit genuinely holds 22.06 — so you get the current rotational-test standard on the box you actually buy.

The 5/5 SHARP score: what it measures

The headline is the SHARPrating. SHARP is the UK government's independent helmet-safety programme: it buys helmets off the shelf (so manufacturers can't cherry-pick samples) and impact-tests them at multiple speeds and points, then publishes a 1-to-5-star rating. A 5/5is the top score, and it's rare — it means the K6 S performed excellently across SHARP's battery of linear impact tests. Unlike a homologation, which is pass/fail, SHARP is a graded, comparative result, which is why it's the closest thing to a consumer crash-test score that exists.

What the score does — and doesn't — tell you

A 5/5 SHARP score is strong, genuinely independent evidence that the K6 S manages impact energy well. But read it for what it is. SHARP primarily rates linear impactperformance; it is not the same test as ECE 22.06's rotational assessment, so the two complement rather than replace each other — and the K6 S holds both. SHARP also tests the specific model and generationit bought, so the rating applies to the helmet tested. And no rating protects you if the helmet doesn't fit: SHARP's own advice, and ours, is that a correctly-fitted helmet is what makes any score real. Our measuring guide is the companion to this page.

How it compares

Very few full-face helmets pair genuine US ECE 22.06 with a 5/5 SHARP score, and the K6 S adds class-leading low weight (~1,255 g) on top — which is why we call it the safety-data leader of the full-face class. Its closest rival on data is the HJC RPHA 1N, which counters with FIM racing homologation rather than a SHARP score (see RPHA 1N vs K6 S). The Shoei RF-1400's European twin, the NXR2, is also 5/5 SHARP, but the US RF-1400 itself is a Snell build.

Confirming it on the helmet you buy

Because certification can differ by market, it's worth confirming the marks on your actual helmet rather than trusting a listing. Inside a genuine US K6 S you'll find the DOT label and the ECE 22.06approval label (a white tag showing the E-mark and an approval number beginning 06, the "06" denoting the 22.06 revision). The SHARP score isn't printed on the helmet — it's published on SHARP's website for the model, linked in our sources below. Checking the ECE label's revision number is the single most useful habit this whole site tries to teach: it's how you tell a genuine 22.06 helmet from an older 22.05 one, or a US build from a European one.

One caveat specific to independent scores: SHARP tests the generation it buys, so make sure the score you're reading is for the current K6 S and not a predecessor. AGV's own materials and the SHARP database both refer to the current model, and the two agree — DOT + ECE 22.06 with a 5/5 SHARP result — which is exactly the alignment you want to see before trusting a safety claim.

The bottom line

The AGV K6 S's safety rating is about as strong as a full-face's gets: genuine US DOT + ECE 22.06 anda perfect 5/5 SHARP score, in a very light shell. If independent, published safety data is what you want to buy on, it's one of the best-documented helmets on the market — just fit it correctly, because that's what turns a great rating into real protection.
