JIEKAI JK902 review

A modular helmet with a dual-visor design and vents, published for head circumferences of 55 to 62 cm. The title cites DOT certification while the bullets cite FMVSS-218 and ECE without a version.

The bottom line Publishes a proper sizing range and contradicts itself on the approval: DOT in the title, FMVSS-218 and ECE in the bullets, no version anywhere. Both statements are reported here because the listing makes both.

What the listing publishes, and where it disagrees with itself

The title cites DOT certification. The bullets state the helmet meets or exceeds FMVSS-218 and ECE — without giving an ECE series of amendments.

Those are different claims. FMVSS-218 is the United States standard behind a DOT marking; ECE is a United Nations regulation applied in Europe, and it comes in numbered series. A listing citing ECE with no version has not said which document was applied. Both statements are recorded here as the listing makes them, and the strap label is where the actual approval is printed.

What is usefully published

A head circumference range of 55 to 62 cm, which is the comparable sizing figure and is more useful than a letter. A dual-visor design, vent slots, and a heavily padded liner.

The rows this seller leaves empty

The P or P/J marking, the weight, and whether the liner is removable.

Availability

Around 79 € on the German, French, Italian and Spanish Amazon stores, in the single reading behind this page.

Priced in local currency, which the euro range above deliberately leaves out, it also appears on the British Amazon store.

Nothing whatever came back from the American Amazon store, so the buy button there opens a search instead of an empty page.

What riders ask about this one

Is DOT the same as ECE?

No. They are separate documents from separate bodies with different test programmes. A helmet can carry one, the other or both, and the strap label records what was actually granted.

Why does the ECE version matter?

Because a series of amendments changes what is tested. A listing citing ECE without a version has not said which document the helmet was approved against.

Who this one is for

A rider who reads the approval on the strap label themselves and wants a modular at this price.
