LS2 lists \u003cstrong\u003etwo separate parts\u003c\/strong\u003e in the rear area of this helmet: this one, catalogued as the rear vent (806902AVR11), and a second catalogued as the back vent (806902AVB11). They are different components and we are not going to guess which sits where on your shell. Take the damaged part off and read the number moulded into it, or order both — between them they cost less than thirty euros.\u003c\/p\u003e\n\n\u003cp\u003eWhat the rear ventilation does is the least intuitive part of a helmet's airflow. It does not blow air out. It sits in the low-pressure wake behind the shell, and that pressure difference is what pulls air through the EPS channels from the intakes at the front. Lose it and the system loses its suction, which is why a helmet missing a rear cover feels warmer rather than cooler.\u003c\/p\u003e\n\n\u003ch3\u003eFits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLS2 FF902 Scope II\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003ePart\u003c\/em\u003e — rear air vent cover\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFinish\u003c\/em\u003e — matt black\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eGeneration\u003c\/em\u003e — ECE 22.06 version\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003e🔴 Note\u003c\/em\u003e — LS2 lists a separate back vent (806902AVB11) — order by part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFitting\u003c\/em\u003e — external, no liner removal\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFits\u003c\/em\u003e — all sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCompatible helmets\u003c\/em\u003e — LS2 FF902 Scope II\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart number\u003c\/em\u003e — 806902AVR11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LS2","offers":[{"title":"Default Title","offer_id":53597195829514,"sku":"806902AVR11","price":10.92,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/806902AVR11_00.png?v=1788165429","url":"https:\/\/inter-pace.com\/en-gb\/products\/ls2-ff902-scope-ii-air-vent-rear-matt-black","provider":"Inter-Pace","version":"1.0","type":"link"}
