For a 2003 KTM 450 EXC, compatible plastics typically include those from other KTM models of the same era, such as the 2003 KTM 250 EXC and 400 EXC. Additionally, aftermarket companies often produce compatible plastics that fit multiple KTM models, so checking with brands like Cycra or UFO can provide suitable options. Always ensure that the specific year and model match to guarantee proper fitment.
