The four-layer cotton gauze is treated with a specially formulated oil that creates a tacky surface to catch particulates, while the open weave structure ensures airflow remains as unrestricted as possible. The result is a filter that does two jobs simultaneously: it lets the twin breathe more freely on the way to the redline, and it keeps abrasive particles away from the piston rings and valves over tens of thousands of kilometres.\u003c\/p\u003e\u003ch2\u003eLong-Term Value and Sustainability\u003c\/h2\u003e\u003cp\u003eUnlike a paper filter that must be discarded at every service interval, the FM01117 is designed to be washed with BMC's dedicated cleaning kit, dried, and re-oiled before refitting. Over the ownership period of an RS 660 this approach represents a meaningful saving in both cost and consumable waste — a consideration that sits well with riders who spend time on the bike rather than the forecourt.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe BMC FM01117 is a direct OEM-replacement air filter engineered specifically for the Aprilia RS 660 across all model years from 2020 to 2026. No modifications to the airbox or associated components are required — the rubber frame locates and seals exactly as the factory filter does.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RS 660 (2020)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2021)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2022)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2023)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2024)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2025)\u003c\/li\u003e\n\u003cli\u003eAprilia RS 660 (2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: BMC\u003c\/li\u003e\n\u003cli\u003ePart number: FM01117\u003c\/li\u003e\n\u003cli\u003eFilter type: Replacement air filter (drop-in OEM fitment)\u003c\/li\u003e\n\u003cli\u003eFilter media: Four-layer oiled cotton gauze\u003c\/li\u003e\n\u003cli\u003eFrame material: Rubber\u003c\/li\u003e\n\u003cli\u003eSupport layer: Aluminium mesh\u003c\/li\u003e\n\u003cli\u003eMaintenance: Washable and reusable\u003c\/li\u003e\n\u003cli\u003eFitment: Aprilia RS 660 (2020-2026)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMC","offers":[{"title":"Default Title","offer_id":53168728277258,"sku":"FM01117","price":78.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FM01117_5f832a32-5ee9-434b-95b2-2427e1242f0a.png?v=1780812802","url":"https:\/\/inter-pace.com\/products\/bmc-fm01117","provider":"Inter-Pace","version":"1.0","type":"link"}
