BMC Air Filter MBK X-OVER 125 – FM840/04 (Multi-bike)

The BMC FM840/04 air filter is the high-performance Standard version replacement filter for the MBK X-OVER 125. BMC's iconic red filter for everyday use: more airflow, better filtration, and a longer lifespan than the original paper filter.

• Increased airflow to the engine: BMC cotton gauze has wider meshes than OEM paper, allowing for greater flow without losing filtration.
• 97.5% filtration efficiency — ISO5011 standard: blocks all impurities larger than 7 microns, superior protection to the original filter.
• Larger filtration area: maximum permeability and airflow compared to standard panel filters.
• Washable and reusable: regenerates with the official BMC kit every 20,000–25,000 km, lasting the lifetime of the motorcycle.
• The choice of champions: BMC equips the most important Formula 1, MotoGP, and WorldSBK teams.

Specifically designed for the MBK X-OVER 125. Direct installation in the original airbox without any modifications.
