BMC Race Air Filter for Honda CBR 250R
The BMC FM645/04RACE is a washable Race replacement engine air filter designed for compatible Honda motorcycles. BMC officially confirms fitment for the Honda CBR 250 R from 2011 to 2013, CBR 300 R from 2015 to 2022 and CB 300 F from 2015 to 2018. It installs inside the motorcycle's original airbox as a replacement for the compatible factory air filter.
Washable Oiled Cotton Construction
The filter uses multi-layer cotton gauze soaked with low-viscosity oil and protected by epoxy-coated alloy mesh. BMC's Full Moulding manufacturing system creates the characteristic filter structure from a single mould without welded joints. The filter is supplied pre-oiled and can be washed and regenerated using the appropriate BMC regeneration kit for continued reuse.
Original Airbox Replacement
BMC states that its replacement air filters combine increased airflow with efficient filtration and are designed to retain impurities from as small as 7 microns. The FM645/04RACE uses a panel configuration with an outside width of 117 mm and outside length of 187 mm. It provides a reusable filtration solution while retaining installation within the compatible Honda motorcycle's original airbox.
