BMC Air Filter for BMW R 1250 GS
The BMC FM764/20 is a washable replacement engine air filter designed for compatible BMW boxer motorcycles. For the primary application, BMC officially lists the BMW R 1250 GS and R 1250 GS Adventure Euro5 from 2019 to 2024. The filter installs inside the motorcycle's original airbox as a replacement for the compatible factory air filter while retaining the standard intake arrangement.
Washable Oiled Cotton Construction
The filtration element uses multi-layer oiled cotton gauze protected by epoxy-coated alloy mesh. BMC's Full Moulding manufacturing process forms the 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, allowing continued reuse after servicing.
Original Airbox Replacement
BMC states that its replacement-filter technology provides increased airflow combined with efficient filtration and can retain impurities from as small as 7 microns. FM764/20 is classified as a panel filter and has an outside width of 115 mm and outside length of 174 mm. It provides a reusable replacement while retaining the compatible BMW motorcycle's original airbox configuration.
