{"product_id":"mt-helmets-thunder-4-r-sv-fast-c5-matt-red-helmet","title":"MT-Helmets Thunder 4 R SV Fast C5 Full-Face Helmet – Matt Red","description":"\u003cp\u003eFast C5 is a matt red helmet with black angular camouflage laid over it — layered wedges and repeated X-motifs running from the chin bar over the crown into the tail. It is the loudest Thunder MT builds and the only one of the four new colourways we have been able to photograph.\u003c\/p\u003e\n\n\u003ch3\u003eAbout the Fast C5 graphic\u003c\/h3\u003e\n\u003cp\u003eThe base is a saturated red-orange, matt. Over it sit black shapes in two densities: broad angular wedges that follow the shell's panel lines, and a scatter of smaller X and arrow forms that break up the flat areas. The visor mechanism cover and the vent trims are gloss black; MT is lettered in black at the brow.\u003c\/p\u003e\n\u003cp\u003eThe pattern is doing something specific with the shape underneath it. The wedges follow the actual panel breaks in the shell, which makes a fairly full sport-touring form read narrower than it is — the same trick pinstriping plays on a car, applied to a helmet. Cover the graphic and the shell looks noticeably bigger.\u003c\/p\u003e\n\u003cp\u003eThe second thing worth noticing is where the pattern stops. The black shapes thin out towards the crown and disappear entirely under the spoiler, so from directly behind — the view a following driver has — the helmet reads as a solid red object rather than as broken camouflage. That is the right way round: camouflage patterns genuinely do reduce how quickly an object is resolved, and this one has been kept off the surface that matters most for being seen.\u003c\/p\u003e\n\n\u003ch3\u003eMatt over a strong colour: what you are choosing\u003c\/h3\u003e\n\u003cp\u003eTwo things are true of every matt finish and worth knowing before you buy one. It cannot be polished: a swirl or a scuff in a matt clearcoat is permanent, where the same mark comes out of gloss with a mild compound. And red-orange pigment is among the least UV-stable in any paint system.\u003c\/p\u003e\n\u003cp\u003eIn exchange you get a surface that hides the fine handling marks a helmet collects from being carried by the strap, set down on café tables and hung off mirrors — and one that never throws a hotspot into a photograph. Store it out of prolonged direct sun when it is off your head, wash it with a wet cloth and never a dry one, and it holds up for years.\u003c\/p\u003e\n\n\u003ch3\u003eHow long a helmet lasts, and why\u003c\/h3\u003e\n\u003cp\u003eTwo triggers end a helmet's life, and only one of them is visible.\u003c\/p\u003e\n\u003cp\u003eAny impact. The EPS liner works by crushing, once. It does not spring back and the crushed area is invisible from outside — a helmet that has been dropped hard onto a kerb or that took a knock in a fall is finished, however perfect the paint. This is the rule people break most often, usually because the helmet looks fine.\u003c\/p\u003e\n\u003cp\u003eAround five years from first use, regardless of mileage. The EPS gradually loses its ability to crush progressively, the adhesives holding the liner to the shell age, and the padding compresses permanently. A helmet worn twice a year ages nearly as fast as one worn daily, because the clock is chemistry rather than use.\u003c\/p\u003e\n\n\u003ch3\u003eThe Fast graphic across the range\u003c\/h3\u003e\n\u003cp\u003eMT applies the Fast pattern to more than one colourway. It is worth knowing if you are choosing between them: the pattern is identical, the ground colour is not, and the graphic reads very differently over a light base than over this saturated red. On this one the black shapes are the quiet element and the red carries the helmet.\u003c\/p\u003e\n\n\u003ch3\u003eAir through the helmet\u003c\/h3\u003e\n\u003cp\u003eMT enlarged the intakes for the R and reshaped the spoiler that covers the rear exhaust — the two changes that address the most common complaint about the Thunder 4 SV before it.\u003c\/p\u003e\n\u003cp\u003eBoth halves are needed. A helmet ventilates because of a pressure difference, not because holes exist: the intakes sit in high-pressure air at the brow, the exhaust sits in the low-pressure wake behind the spoiler, and the flow follows from one to the other. Generous intakes with a poor outlet give you pressure on the forehead and a hot crown, which is the failure most cheap helmets share.\u003c\/p\u003e\n\n\u003ch3\u003eEverything else that is fitted\u003c\/h3\u003e\n\u003cp\u003eA Pinlock DKS435 Max Vision insert comes in the box. The MT-V-28C screen sits on the MT-M-28X mechanism with tool-free MT-QVSS release and a locking catch; a shade drops from inside the shell; a nose deflector keeps breath off the screen; the strap closes on a micrometric ratchet; and the lining comes out entirely and has speaker recesses. Sizes run XS to 3XL.\u003c\/p\u003e\n\n\u003ch3\u003eECE 22.06 · no DOT\u003c\/h3\u003e\n\u003cp\u003eThe current European standard, mandatory since January 2024: 18 impact points against the 22.05's five, several speeds, an oblique impact against an abrasive anvil for rotational loading, and a Brain Injury Criterion ceiling. No DOT marking is published for the Thunder 4 R.\u003c\/p\u003e\n\n\u003ch3\u003eThe Thunder name and SHARP\u003c\/h3\u003e\n\u003cp\u003eSHARP rates an older \"MT Thunder\" and \"MT Thunder 3\" at four stars. Those are earlier, different helmets — not this one. The Thunder 4 R has not been SHARP-tested, and we will not carry a rating across on the strength of a shared name. The only MT model in our range with a real SHARP result is the Track SV.\u003c\/p\u003e\n\n\u003ch3\u003eCleaning a matt helmet\u003c\/h3\u003e\n\u003cp\u003eThe single rule: never dry. Road dust is mineral and therefore abrasive, and dragging it across a matt clearcoat leaves marks with no correction path — matt cannot be polished at all.\u003c\/p\u003e\n\u003cp\u003eRinse or soak first with plain water and let the grit float off, then a soft wet cloth with no pressure. Insects come off under a damp cloth laid over them for a minute; scrubbing them etches the clearcoat, because insect remains are acidic and a hot afternoon does the rest.\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 for this model.\u003c\/li\u003e\n\u003cli\u003eNo tinted screen supplied.\u003c\/li\u003e\n\u003cli\u003eMatt paint cannot be corrected, and this pigment fades in prolonged sun.\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 — Fast C5, matt red with black angular graphics\u003c\/li\u003e\n\u003cli\u003eProtective bag, user manual and MT Helmets stickers\u003c\/li\u003e\n\u003cli\u003ePinlock DKS435 Max Vision insert included.\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 — 1375538C52 (XS–3XL: …03 to …09)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eColour \/ finish\u003c\/em\u003e — Fast C5 — matt red with black angular graphics\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;
