This radiator plug is used to be welded to plug holes from inlets/outlets that have been removed from radiators. The 2010-2013 Honda CRF250R/2009-2012 Honda CRF450R radiators require several inlets/outlets to be relocated, so this plug is designed to plug the holes that are left in the radiator from removing those inlets/outlets. This radiator plug is a flat piece of aluminum made from 6061 aluminum. You can see our radiator instruction manuals here.
