One of the few gripes I have about the '14 300 RR is the quality of the plastic louvre guards on the rads. They are particularly thin and flimsy and they rattle really badly when riding. One has already split and both are wearing on the locating pins and going brittle from the heat.
Given that the rads themselves look like the pre 2005 KTM units from the RFS engined models, has anyone tried the KTM louvre guards from these rads as replacements? I would expect that the Acerbis plastic will be more robust as I have had 3 post-2005 KTMs and never had an issue with the rad guards. These had different fixings to the Beta ones with pins on the outside and circular lugs on the frame side locating over the fixing bolts.
