BMC FM01139 : BMC Air Filter - BMW R Nine T

The knowledge and experience acquired on the track is transposed to the road in order to offer high-performance products that are constantly evolving to satisfy even the most demanding riders.

• One-piece filter (without any joints that favour breakage)


• Special cotton filter material saturated in low-viscosity oil


• Epoxy mesh is highly resistant to fuel fumes and oxidation


• Washable and therefore reusable cotton


• Optimal air flow guarantees a minimum loss of power compared to traditional paper filters

The characteristics of a cotton filter can be summarised as follows :

• Permeability : the filter must create the lowest possible obstacle to enable the highest passage of air


• Screening : to ensure that all foreign bodies in the air are prevented from entering


• Retention : the retention of all solid particles

Cotton Filter can be re-used several times after having been washed with a special detergent and re-soaked in oil.
