Green is rare on helmets at any price and this is the only one in MT's modular range. Under a matt finish it reads as an earth tone rather than as a sporting colour, which suits a touring helmet.

A chin guard that opens — and the P/J question

🔵 Practise the one-handed open before you need it. The release is a single button under the chin guard, and finding it in winter gloves for the first time at a toll booth is not ideal.

The MT-Micrometric+ double-hook closure is separately designed against accidental opening.

About the Highlands C6 graphic

A deep green under matt belongs to the landscape rather than to a race paddock, and on a helmet worn for long distances through open country that is the more comfortable register. It is also a genuinely durable choice — green carries no reference to a particular season's palette, so it will look current in five years in a way a bright graphic will not. Practically it sits mid-range: better at hiding road film than the pale versions, more visible in flat light than the blacks. 🔵 Matt is washed rather than polished, and it holds dry dust more readily than gloss.

HIRP, ECE 22.06 and DOT

The structure is conventional and appropriate: an injection-moulded HIRP shell to spread the load and resist penetration, over a polystyrene liner that absorbs energy by permanently crushing.

🔵 A crushed liner does not recover. After a real impact the helmet is finished, whatever it looks like from outside — and on a flip-up the hinge should be checked annually regardless.

MT-ESP — a sun visor that meets the nose deflector

🔵 A tinted visor is not road-legal at night or in poor visibility in most European countries, and the rules differ between them. A retractable internal shield sidesteps the question entirely — it is up when the light goes.

The MT-V-35 main visor stays clear behind it, with a Pinlock lens fitted.

MT-FSOS, MT-ESLS and the Pinlock in the box

Look after the visor and it will outlast the padding. Never wipe a dry visor — road dust is abrasive and dragging it across the surface leaves permanent fine scratches that flare against oncoming headlights at night.

🔵 Wet it first, every time. The MT-ESLS release makes replacing a scratched visor straightforward.

The double-hook closure

What a micrometric closure gives you over a simple buckle is fine adjustment. You are not choosing between two holes; you are setting the strap to the millimetre and clicking to the same place every time.

🔵 The double-hook engagement is what makes that click mean something.

A spoiler that hides the exhaust

Airflow only happens if there is somewhere lower in pressure for the air to go, which is why putting the exhaust behind the spoiler is sensible: that is exactly where the pressure is lowest.

🔵 MT documents the layout. No independent measurement of the Atom 2 SV's airflow exists.

Interior, fit and the chin curtain

🔵 On a flip-up there is one extra maintenance item a fixed full-face does not have: the chin-guard pivot and its seals. Check them annually — a seized hinge ends a modular helmet as surely as a crushed liner.

The interior itself comes out entirely for washing.

Intercom preparation

🔵 The most common reason riders abandon an intercom is a speaker pressing on the ear over a long day, and it is almost always a depth or positioning problem rather than a fault of the system.

Measure yours before assuming they will fit.

Where it sits in MT's range

Buying a Pure version rather than a graphic saves 13 € and changes nothing else — same HIRP shell, same MT-V-35 visor, same MT-ESP sun shield, same included Pinlock lens.

🔵 The graphics buy artwork, not capability.

When something wears out

Genuine parts matter more on a helmet than on most things, because the visor, the chin-guard mechanism and the retention system are part of what was certified to ECE 22.06 and DOT.

Everything we stock for the Atom 2 SV is MT's own.

Size guide

Specification

• Model — MT-Helmets Atom 2 SV
• Part number — 1335C94C6203
• Colour — Highlands C6 — Matt green
• Homologation — ECE 22.06 and DOT; MT states the helmet exceeds both
• 🔴 P/J dual homologation — not documented by MT. P/J is what makes riding with the chin guard raised legal in most of Europe — check the approval label on the helmet before relying on it
• 🔴 Safety rating — none — SHARP has never listed the Atom 2 SV, and modular helmets are rarely tested by the programme. No ADAC or Snell result, and no independent road test has been published
• Helmet type — Modular / flip-up, all-round touring
• Shell — HIRP (High Impact Resistant Polymer), with a rear spoiler concealing the ventilation exhaust
• Weight — approx. 1.7 kg — typical for a thermoplastic flip-up; the format carries 150–250 g over a fixed full-face
• Sizes — XS to XXL (six sizes)
• Chin guard — single-button release, operable one-handed
• Visor — MT-V-35 with MT-FSOS fast opening including an automatic anti-fog position, and MT-ESLS release with a dedicated ventilation position
• Anti-fog — Pinlock® DKS512 included as standard; FogOff FOG013 is a compatible alternative
• Sun visor — MT-ESP retractable shield with extended coverage that aligns with the nose deflector
• Retention — MT-Micrometric+ with a double-hook MT-MDTC engagement against accidental opening
• Interior — fully removable and washable
• Also supplied — chin curtain
• Communication — intercom-ready — no system supplied
• Impact liner — expanded polystyrene — crushes once and does not recover; replace the helmet after any real impact
• Serviceability — visor, Pinlock lens, sun shield, lining, cheek pads and chin curtain all available separately
• Flip-up maintenance — check the chin-guard pivot and its seals annually — dust and water are what seize a modular mechanism
• Manufacturer — MT-Helmets (MT Helmets, Spain)
• Replacement guidance — after around five years of use regardless of condition, and immediately after any impact
• Compared with the Thunder 4 R SV — that fixed full-face is around 200 g lighter and cannot open at a stop. Both use HIRP shells; only the Atom 2 SV adds DOT approval alongside ECE 22.06
• Sizing note — measure around the widest part of your head, about 1–2 cm above the eyebrows, and try the size the chart gives you. A helmet that can be rolled forward off your head with the strap fastened is too large — and on a 1.7 kg modular a poor fit shows itself sooner than on a lighter helmet
• Care — wash the lining by hand a few times a season; never wipe the visor or the sun shield dry, as road dust scratches both permanently

• 1x MT Atom 2 SV helmet
• 1x Pinlock DKS512 anti-fog insert (included)
• 1x protective helmet bag
• User manual and MT Helmets stickers
