BMC Air Filter - FM775/08: designed to ensure healthy engine breathing for Honda 500 roadsters, this oiled cotton filter replaces the original paper elements while maintaining effective filtration and good permeability. Ideal for riders who want a washable and reusable element without complicated modifications.
The performance of a cotton filter is measured by permeability (free passage of air to the airbox), filtration (preventing dust and debris from entering), and particle retention. This model prioritises a compromise between engine protection and airflow to preserve intake responsiveness.
