BMC Racing Air Filter for Aprilia RS 660 (2020-2026) FM01117RACE

BMC's racing pedigree runs deep, and the FM01117RACE air filter for the Aprilia RS 660 is the clearest expression of that heritage in a direct-fit package. Engineered for riders who have pushed their RS 660 beyond stock — remapped ECUs, tuned fuelling, modified components — this Race-spec filter retains the exact geometry of the original unit while unlocking a significantly higher airflow rate, all without sacrificing filtration integrity.

Key Features

• Race-grade filtration media delivers a measurably higher airflow volume compared to the standard filter, feeding modified engines the volume of air they demand.
• Drop-in fitment: the FM01117RACE mirrors the OEM filter's dimensions exactly, so installation requires no cutting, adapting or additional hardware.
• Filtration efficiency remains at the highest level — increased flow does not mean reduced protection; the engine stays shielded from contaminants at every rpm.
• Optimised for modified powertrains where the ECU and supporting components have been tuned for elevated output.
• Instantly recognisable yellow stripe signals Race specification at a glance and distinguishes this filter from BMC's standard Sport range.
• Reusable and cleanable design consistent with BMC's long-standing approach to sustainable, high-performance filtration.

Design, Finish and Heritage

BMC has supplied air filtration to factory race teams for decades, and every detail of the FM01117RACE reflects that background. The signature yellow stripe is more than a visual marker — it communicates that this filter is built to a different standard, one developed on circuits where airflow is a measurable performance variable rather than an afterthought. The filter's construction uses an advanced cotton-gauze-style media that has been tuned specifically for the RS 660's intake characteristics, giving the filter a character as distinctive as the twin-cylinder engine it serves.

Performance on Road and Track

The RS 660 responds eagerly to breathing modifications, particularly when paired with an ECU remap or aftermarket exhaust. The FM01117RACE is designed precisely for this configuration: it removes the airflow restriction present in the standard filter so that the engine management system can work with the fuller charge it has been mapped to expect. The result is a more linear throttle response, improved mid-range pull and a cleaner top-end surge — all traceable back to the quality of air the engine receives on every intake stroke.

Fitment and Compatibility

This filter is a confirmed direct fit for the following motorcycle:

• Aprilia RS 660 — model years 2020 to 2026

It is specifically recommended for RS 660 examples where the ECU or other engine management components have been modified for increased performance. Standard, unmodified motorcycles will see greater benefit from BMC's Sport filter range.
