Air filter or box adapter by KEIHIN (Manufacturer reference: 021.212). This part is designed to ensure the connection between the intake and the filtration system on carburetor setups. Designed for the Cross and Roadster environments, this adapter facilitates the integration of a filtering element or the connection to the air box when the original connections do not match.
This adapter is aimed at motorcyclists working on the intake: configuration transformation, filter replacement, or adaptation of a different carburetor. It operates at the intake manifold level to ensure continuity between the carburetor and the filtering body, maintaining the necessary geometry for installation.
