RB .12 INS Box
RB have released its EFRA and IFMAR homologated .12 Induction Noise System (INS) box. The enclosed foam air filter has been especially designed to make sure the INS box perfectly fits the carburettor without touching the cooling head, while its white foam helps easily check the oil application and cleanliness. As with other noise reduction filters, the RB .12 INS box can also be used as a filter against the rain.
