{"product_id":"mt-helmets-thunder-4-r-sv-highway-a7-gloss-beige-helmet","title":"MT-Helmets Thunder 4 R SV Highway A7 Full-Face Helmet – Gloss Beige \/ Dark Blue","description":"\u003cp\u003eTwo things on this helmet solve the same problem from opposite ends of the day: an integrated sun visor for the light, and a locking visor for the speed. Neither has to be carried, remembered or fitted, and together they are why one helmet can cover a commute that starts in glare and ends in the dark.\u003c\/p\u003e\n\n\u003ch3\u003eThe internal shade, and the case against a tinted screen\u003c\/h3\u003e\n\u003cp\u003eA shade drops from inside the shell on a slider by your left hand.\u003c\/p\u003e\n\u003cp\u003eA tinted screen is optically better and darker — an internal shade sits a centimetre from your eye and has to stay light enough to survive a tunnel, so it is always a compromise. But it is only better on the days you happened to bring it. The failure mode of a tinted visor is not that it is inadequate; it is that you are still wearing it at nine in the evening because swapping meant stopping, and riding home behind a dark screen is considerably worse than riding into the sun behind a clear one.\u003c\/p\u003e\n\n\u003ch3\u003eThe visor lock\u003c\/h3\u003e\n\u003cp\u003eThe MT-V-28C screen runs on the MT-M-28X mechanism and carries a locking catch: a small mechanical latch that holds the visor shut rather than relying on the friction of the detent.\u003c\/p\u003e\n\u003cp\u003eThe failure it prevents is not dramatic and is genuinely unpleasant. At motorway speed a visor lifted three or four millimetres by air pressure lets a jet of cold air straight into one eye, and the instinct is to reach up and push it down — taking a hand off the bar at exactly the wrong moment. The catch removes that whole sequence.\u003c\/p\u003e\n\n\u003ch3\u003eAbout the Highway A7 finish\u003c\/h3\u003e\n\u003cp\u003eGloss. The crown and the front of the shell are a warm off-white shading into beige; the rear quarter and the lower flank are a deep navy, and the two meet along a hard diagonal with a bright orange wedge set into the join. THUNDER 4 R HIGHWAY runs in small type along the bottom edge.\u003c\/p\u003e\n\u003cp\u003eBeige is an unusual base on a sport-touring helmet and a good one under sun: a light shell reflects most of the solar load where a dark one absorbs it and passes it inward. The navy rear keeps the helmet from reading as plain cream, and the orange is small enough to work as punctuation rather than as a second colour.\u003c\/p\u003e\n\n\u003ch3\u003eNoise, and what actually causes it\u003c\/h3\u003e\n\u003cp\u003eWe will not claim this is a quiet helmet, and here is the more useful truth: for most riders the helmet is not what decides the noise.\u003c\/p\u003e\n\u003cp\u003eWhat decides it is the screen on the bike. A screen that sends turbulent air at the base of your helmet makes any lid loud, and a naked machine with clean airflow is frequently quieter than a badly faired one. If a new helmet did not fix your noise problem, the next thing to change is the screen height, not the helmet. And wear plugs above 100 km\/h regardless — wind-induced hearing loss is cumulative, painless and permanent.\u003c\/p\u003e\n\n\u003ch3\u003eThe spoiler is not decoration\u003c\/h3\u003e\n\u003cp\u003eMT reshaped the spoiler for the R. It hides the rear exhaust, and it does aerodynamic work: behind a fairing screen the airflow is turbulent, and a helmet with a tail sits measurably steadier in it than one without.\u003c\/p\u003e\n\u003cp\u003eHigh-speed head-shake is usually blamed on the helmet when the bike's screen is causing it. A spoiler does not remove the cause, but it makes the helmet a less willing participant.\u003c\/p\u003e\n\n\u003ch3\u003eECE 22.06 · no DOT\u003c\/h3\u003e\n\u003cp\u003eMandatory since January 2024: 18 impact points rather than the 22.05's five, several speeds, an oblique impact against a rough anvil for rotational loading, and a Brain Injury Criterion limit. No DOT marking is published for this model, and we do not claim one.\u003c\/p\u003e\n\n\u003ch3\u003eNot the SHARP-rated Thunder\u003c\/h3\u003e\n\u003cp\u003eSHARP lists an older \"MT Thunder\" and \"MT Thunder 3\" at four stars. Those are different, earlier helmets; the Thunder 4 R has not been tested, and we will not let a shared model name imply otherwise. In our MT range only the Track SV holds a genuine SHARP result.\u003c\/p\u003e\n\n\u003ch3\u003eIntercom preparation\u003c\/h3\u003e\n\u003cp\u003eThe lining carries recesses for the speakers of an MT-B01 Rider Sync system, and the shell has a mounting surface for the unit itself.\u003c\/p\u003e\n\u003cp\u003eThe pockets are the part worth checking for, and most product pages never mention them. Without them the speakers sit on top of the lining and are pressed against the outside of your ear by the padding — uncomfortable within twenty minutes, impossible to adjust away, and painful on a long day. No intercom is supplied; only the space for one.\u003c\/p\u003e\n\n\u003ch3\u003eThe rest of what is fitted\u003c\/h3\u003e\n\u003cp\u003eA Pinlock DKS435 Max Vision insert comes in the box — rare at this price and the reason this helmet works in winter. Sizes run XS to 3XL, 53 to 66 cm. The screen releases without tools through MT-QVSS, a nose deflector keeps breath off the inside of it, the strap closes on a micrometric ratchet, and the whole lining lifts out for washing.\u003c\/p\u003e\n\n\u003cp\u003eA word on the gloss finish while we are on care: it shows fingerprints and dust more readily than matt, and in exchange it can be corrected: a light swirl polishes out of a gloss clearcoat and is permanent in a matt one. Never wipe a dry shell — grit dragged across gloss is exactly how those swirls appear in the first place. A wet cloth first, every time.\u003c\/p\u003e\n\n\u003ch3\u003eGetting the size right the first time\u003c\/h3\u003e\n\u003cp\u003eMeasure the head at its widest, roughly 1–2 cm above the eyebrows, and take that circumference to the table below. Between two sizes, take the smaller: comfort padding compresses two or three millimetres in the first hours and then stops, so a helmet that starts slightly firm on the cheeks ends up right, while one that is comfortable in the shop ends up loose by the second month.\u003c\/p\u003e\n\u003cp\u003eThe EPS liner behind the padding does not compress at all in normal use — it only crushes in an impact, which is its whole purpose. That is why \"it will give\" is wrong as advice: what gives is a couple of millimetres of fabric, not the structure.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it does not have\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo DOT marking published.\u003c\/li\u003e\n\u003cli\u003eNo SHARP rating — see above.\u003c\/li\u003e\n\u003cli\u003eNo tinted screen supplied.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMT Thunder 4 R SV helmet — Highway A7, gloss beige and dark blue\u003c\/li\u003e\n\u003cli\u003eProtective bag, user manual and MT Helmets stickers\u003c\/li\u003e\n\u003cli\u003ePinlock DKS435 Max Vision insert supplied.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSize guide\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eHead circumference\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eXS\u003c\/td\u003e\n\u003ctd\u003e53–54 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eS\u003c\/td\u003e\n\u003ctd\u003e55–56 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eM\u003c\/td\u003e\n\u003ctd\u003e57–58 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL\u003c\/td\u003e\n\u003ctd\u003e59–60 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eXL\u003c\/td\u003e\n\u003ctd\u003e61–62 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eXXL\u003c\/td\u003e\n\u003ctd\u003e63–64 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3XL\u003c\/td\u003e\n\u003ctd\u003e65–66 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eModel\u003c\/em\u003e — MT-Helmets Thunder 4 R SV · \u003cem\u003ePart number\u003c\/em\u003e — 1375E15A71 (XS–3XL: …03 to …09)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eColour \/ finish\u003c\/em\u003e — Highway A7 — gloss beige with dark blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eHomologation\u003c\/em\u003e — ECE 22.06 · no DOT published\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSafety rating\u003c\/em\u003e — none for the 4 R\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eType\u003c\/em\u003e — full-face, sport-touring\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eShell\u003c\/em\u003e — HIRP (High Impact Resistant Polymer), approx. 1,500 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSizes\u003c\/em\u003e — XS to 3XL (53–66 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eVisor\u003c\/em\u003e — MT-V-28C, MT-M-28X mechanism, MT-QVSS release, locking catch\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eAnti-fog\u003c\/em\u003e — Pinlock DKS435 Max Vision included\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSun visor\u003c\/em\u003e — integrated drop-down shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eVentilation\u003c\/em\u003e — enlarged intakes, reworked spoiler with exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDeflector\u003c\/em\u003e — nose deflector\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eRetention\u003c\/em\u003e — micrometric ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInterior\u003c\/em\u003e — fully removable and washable, speaker pockets\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCommunication\u003c\/em\u003e — MT-B01 Rider Sync prepared;
