Retaining the precise geometry of the original filter for a direct, tool-free swap, it is constructed from a purpose-developed filtration medium that delivers a measurably higher airflow rate while maintaining the filtration integrity your engine depends on. If your R1 or R1M has been mapped or modified for elevated output, this is the filter the build calls for.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePurpose-developed race filtration medium increases airflow volume over the OEM unit without compromising particle retention — the foundation of genuine power gains on a tuned engine.\u003c\/li\u003e\n\u003cli\u003eTrack-derived construction draws directly on BMC's motorsport programme, making it the natural choice for riders running custom ECU maps or modified intake and exhaust systems.\u003c\/li\u003e\n\u003cli\u003eDual-function performance: higher flow and first-rate filtration work simultaneously, so the engine breathes freely and remains protected from abrasive contaminants.\u003c\/li\u003e\n\u003cli\u003eIdentical external dimensions to the original Yamaha filter ensure a straightforward, no-modification installation — drop it in and ride.\u003c\/li\u003e\n\u003cli\u003eDistinctive yellow stripe provides instant visual identification in the airbox, confirming the race-specification component is fitted at a glance.\u003c\/li\u003e\n\u003cli\u003eOptimised specifically for modified Yamaha YZF-R1 and YZF-R1M engines where the OEM filter becomes a restriction to achieving the full benefit of tuning work.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction \u0026amp; Materials\u003c\/h2\u003e\u003cp\u003eBMC's Racing range is built around a proprietary multi-layer cotton gauze medium, oiled and layered to precise tolerances within a robust frame. The material is chosen for its ability to flow significantly more air than paper or foam alternatives while presenting a consistently fine filtration barrier to dust, grit, and airborne debris. The yellow racing stripe is not a cosmetic afterthought — it is BMC's own house mark for their Race-specification product tier, distinguishing it clearly from the street-oriented Evolution range in both appearance and airflow calibration.\u003c\/p\u003e\u003ch2\u003ePerformance \u0026amp; Track Use\u003c\/h2\u003e\u003cp\u003eOn a stock Yamaha YZF-R1 the OEM air filter is a calculated compromise between flow, longevity, and manufacturing cost. Once the ECU mapping, exhaust, or throttle bodies are modified, that compromise becomes a genuine bottleneck. The FM856\/04RACE removes the intake restriction that limits the return on tuning investment, allowing the engine to draw in the volume of air a modified fuelling map expects. The result is a more complete power delivery across the rev range rather than simply at peak revs, which is especially apparent on circuit where the engine is held at high load for extended periods.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis filter is a direct replacement for the following Yamaha models and chassis codes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 RN32 (2015-2016)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN32 (2015-2016)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1 RN49 (2017-2020)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN49 (2017-2020)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1 RN65 (2021-2026)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R1M RN65 (2021-2026)\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: FM856\/04RACE\u003c\/li\u003e\n\u003cli\u003eFilter type: Race air filter\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R1 \/ YZF-R1M, chassis codes RN32, RN49, RN65\u003c\/li\u003e\n\u003cli\u003eModel years: 2015-2026\u003c\/li\u003e\n\u003cli\u003eInstallation: Direct OEM replacement, no modification required\u003c\/li\u003e\n\u003cli\u003eVisual identifier: Yellow racing stripe\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMC","offers":[{"title":"Default Title","offer_id":53168724574474,"sku":"FM856\/04RACE","price":82.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FM856_4a1a4847-2f36-4679-bf57-05a5f355620a.png?v=1780812649","url":"https:\/\/inter-pace.com\/cs\/products\/bmc-fm856-04race","provider":"Inter-Pace","version":"1.0","type":"link"}
