BMC Replacement Air Filter for Aprilia RS 660 (2020-2026) FM01117

Engineered with knowledge drawn directly from motorsport, the BMC FM01117 replacement air filter slots into your Aprilia RS 660 and immediately goes to work improving airflow, filtration efficiency and long-term engine protection — all without ever needing a replacement filter again.

Key Features

• Four-layer oiled cotton gauze construction delivers a superior balance of airflow and filtration, channelling more air to the engine for improved throttle response and power output.
• Washable and reusable design eliminates the recurring cost and waste of disposable paper filters — clean it, re-oil it, refit it.
• Enhanced dirt absorption capacity traps more fine particles than a standard OEM filter, keeping combustion cleaner across long rides and varied road conditions.
• Optimised pressure-drop ratio reduces intake restriction, lowering the energy the engine spends drawing air and freeing up usable performance.
• Robust rubber frame resists cracking and ensures a consistent, leak-free seal within the airbox every time the filter is refitted.
• Aluminium mesh support layer protects the cotton media against fuel vapour and oxidation, extending service life well beyond a conventional filter.

Race-Derived Filtration for the Road

BMC has spent decades supplying air filtration technology to factory race teams across MotoGP, World Superbike and rally raid — and the FM01117 carries that heritage into a direct-fit, street-legal package for the RS 660. 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.

Long-Term Value and Sustainability

Unlike 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.

Fitment and Compatibility

The 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.
