An injection-moulded ABS shell, EPS impact liner, clear visor, quick-release chin strap, and soft polyester comfort lining make it a straightforward, reliable helmet for street, touring, and off-road riding. Seven sizes run from S to 4XL (67–68cm) — a genuine advantage for larger riders who struggle to find a certified full-face at the top of the range.\u003c\/p\u003e\n\u003cp

and around the back. Take three readings and use the largest. A correctly sized helmet applies firm, even pressure with no gaps and feels snug for the first 15–20 minutes before the liner settles. If it feels comfortable immediately, it's likely one size too large. At the larger sizes (3XL–4XL) head shape varies more than circumference alone, so confirm the helmet sits without persistent pressure points before the return window closes. If your measurement falls at a size boundary, choose the larger size.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e✔ Package Includes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e✓ 1 × MT Helmets Thunder 4 SV Full Face Helmet\u003cbr\u003e✓ Secure Packaging\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eTriple-certified protection in a clean full-face profile — available up to 4XL.\u003c\/p\u003e","brand":"Lane ProMotor","offers":[{"title":"GLOSS EXA RED \/ S(55–56cm)","offer_id":47464520876084,"sku":"191288010:-1#GLOSS EXA RED;200329261:-1#S","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ M(57–58cm)","offer_id":47464520908852,"sku":"191288010:-1#GLOSS EXA RED;200329261:-2#M","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ L(59–60cm)","offer_id":47464520941620,"sku":"191288010:-1#GLOSS EXA RED;200329261:-3#L","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ XL(61–62cm)","offer_id":47464520974388,"sku":"191288010:-1#GLOSS EXA RED;200329261:-4#XL","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ XXL(63–64cm)","offer_id":47464521007156,"sku":"191288010:-1#GLOSS EXA RED;200329261:-5#XXL","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ 3XL(65–66cm)","offer_id":47464521039924,"sku":"191288010:-1#GLOSS EXA RED;200329261:-6#3XL","price":459.0,"currency_code":"AUD","in_stock":true},{"title":"GLOSS EXA RED \/ 4XL(67–68cm)","offer_id":47464521072692,"sku":"191288010:-1#GLOSS EXA RED;200329261:-7#4XL","price":459.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/4780\/2932\/files\/Hc7ce57f816ca44469117f7b02dc910bbg.webp?v=1770387622","url":"https:\/\/lanepromotor.com\/products\/mt-helmets-thunder-4-sv-full-face-motorcycle-helmet-dot-ece-ccc-certified-abs-shell-s-4xl","provider":"Lane ProMotor","version":"1.0","type":"link"}
