{"product_id":"ls2-ff805-thunder-gp-aero-ursus-black-racing-helmet","title":"LS2 FF805 Thunder GP Aero Ursus Black – Full-Face Racing Helmet ECE 22.06","description":"\u003cp\u003eMost carbon helmets are painted over. This one is not: the Ursus Black graphic is a handful of white and grey line marks laid across bare gloss carbon, so the weave stays the surface you actually look at. Underneath it is LS2's FF805 Thunder GP Aero — 100 per cent carbon, 1,280 g declared, ECE 22.06, double D-ring.\u003c\/p\u003e\n\n\u003ch3\u003eUrsus Black: a graphic that stays out of the way\u003c\/h3\u003e\n\u003cp\u003eA thin white claw mark sweeps back across the flank, a second across the crown, and a small pale bear device sits behind the visor mechanism. Everything else is the shell itself. On a bright day the twill catches light and the helmet reads as dark metallic grey rather than black; under cloud it goes almost flat.\u003c\/p\u003e\n\u003cp\u003eThis is the version to buy if you want the material to be the decoration. It is also the version that shows a badly repaired scuff, because there is no busy pattern to hide it behind.\u003c\/p\u003e\n\n\u003ch3\u003e6K, 9K, and what the weave number actually tells you\u003c\/h3\u003e\n\u003cp\u003eCarbon cloth is described by the number of filaments in each tow: 6K is six thousand, 9K is nine thousand. The GP Aero uses 6K, the GP PRO above it uses 9K.\u003c\/p\u003e\n\u003cp\u003eA finer tow gives a smaller, tighter visual pattern and drapes more easily into tight radii, which matters on a shape with this many creases. A heavier tow lays down more material per ply, so a laminator reaches a target thickness in fewer layers. Neither number is a safety rating on its own — the layup schedule, the resin and the cure do the work — and any shop that tells you 9K is safer than 6K is selling you a number rather than a helmet. What the weave does tell you honestly is that this is structural carbon, not a carbon-look film over fibreglass.\u003c\/p\u003e\n\n\u003ch3\u003e1,280 grams, and where they go\u003c\/h3\u003e\n\u003cp\u003eLS2's declared figure is 1,280 g with a 50 g tolerance. We have not weighed one, so we report it as a manufacturer's claim.\u003c\/p\u003e\n\u003cp\u003eWeight on a helmet is not felt as weight. It is felt as the effort of holding your head still on a bumpy straight and as the ache that arrives somewhere in the fourth hour. Under 1,300 g is the territory where that ache stops being the reason you stop.\u003c\/p\u003e\n\n\u003ch3\u003eAir in at three points, out under the spoiler\u003c\/h3\u003e\n\u003cp\u003eChin intake, a brow intake above the visor, top intakes on the crown. Channels moulded into the EPS carry the air over the scalp, and it exits through the vent under the rear spoiler. A breath deflector sits behind the chin bar to keep exhaled air off the visor.\u003c\/p\u003e\n\u003cp\u003eThe vents are operated with gloves on. The spoiler is structural to the airflow rather than styling: it feeds the exhaust and it steadies a light shell in dirty air.\u003c\/p\u003e\n\n\u003ch3\u003eOne outer shell for the whole size range\u003c\/h3\u003e\n\u003cp\u003eLS2 moulds the GP Aero in one shell size for XS to XXL. That is a real limitation and we would rather write it down than bury it: the external volume you carry is the same whether your head is 53 cm or 63 cm, and the entire size difference is made up in foam thickness.\u003c\/p\u003e\n\u003cp\u003eIn practice that suits the middle of the range best. At XS or XXL, try the helmet on before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eDouble D-ring, and pads that come out under load\u003c\/h3\u003e\n\u003cp\u003eNo ratchet. Two bare hands and a deliberate movement, which is why circuits mandate it — a double D-ring cannot be done up almost right.\u003c\/p\u003e\n\u003cp\u003eThe cheek pads carry LS2's Emergency Release System: red tabs at the base pull the pads clear so the helmet can be removed without rotating the rider's neck. It is equipment for the worst day, and its presence is one of the honest markers of a race shell.\u003c\/p\u003e\n\n\u003ch3\u003ePinlock 120XLT, tear-offs, and a second visor\u003c\/h3\u003e\n\u003cp\u003eThe visor is Class A polycarbonate, wide, scratch-resistant and UV-filtering, on a quick-release mechanism with a button lock closed and tear-off posts already fitted.\u003c\/p\u003e\n\u003cp\u003eLS2 includes the Pinlock 120XLT MaxVision lens rather than selling it after: grade 120 is their strongest anti-fog film, XLT the larger format, MaxVision the version that runs to the edge of the aperture. A tinted visor and tear-off films are in the box as well.\u003c\/p\u003e\n\n\u003ch3\u003eECE 22.06, briefly\u003c\/h3\u003e\n\u003cp\u003eEighteen impact points rather than five, several impact speeds, an oblique test against an abrasive anvil that measures rotational acceleration, and an assessment of the Brain Injury Criterion. Accessories are tested fitted, not removed. It has been the EU requirement since January 2024.\u003c\/p\u003e\n\n\u003ch3\u003eGloss carbon over five years\u003c\/h3\u003e\n\u003cp\u003eGloss is the forgiving finish. Swirls and light scuffs come back out with a mild compound; the same marks in matt clearcoat stay. Bugs and road film lift with less scrubbing.\u003c\/p\u003e\n\u003cp\u003eThe cost is fingerprints and a surface that shows dust. Clear coat over carbon also yellows under long UV exposure, so a helmet stored on a shelf out of the sun will look newer in year five than one that lived on a mirror.\u003c\/p\u003e\n\n\u003ch3\u003eSpare parts, and how long it stays serviceable\u003c\/h3\u003e\n\u003cp\u003eNobody asks this before buying and everybody asks it in year three. LS2 catalogues the FF805 Thunder GP Aero down to individual components: the liner as 806805LNR01, chin vents as 800805AVC11 and AVC12, front vents as AVF11 and AVF12, upper vents as AVU01, AVU11 and AVU12, a rear vent as 800805AVR12, seven visor tints from 800805VIS01 through VIS19, and two Pinlock lenses.\u003c\/p\u003e\n\u003cp\u003eThat matters twice. A crash that takes a vent cover does not write off the helmet, and a liner that has done four summers can be replaced instead of tolerated. The EPS, as on every helmet, cannot be renewed — it crushes once, and an impact you walked away from still ends the helmet's life.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this helmet does not have\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo FIM homologation. The FIM register lists the FF805 Thunder GP PRO for LS2, not the GP Aero.\u003c\/li\u003e\n\u003cli\u003eNo drop-down sun visor, which is normal on a racing shell and still means carrying a tinted screen.\u003c\/li\u003e\n\u003cli\u003eOne outer shell size across six helmet sizes.\u003c\/li\u003e\n\u003cli\u003eNo SHARP, ADAC or Snell result for any FF805 Thunder.\u003c\/li\u003e\n\u003cli\u003eNo published noise measurement.
