Don't know for sure, but usually parts that aren't shared with other bikes become problematic. The Fazer shares engine parts with FZR600R & Thundercat so mostly ok in that department. Bike plastics usually become the problem, particularly ones that get damaged in a crash / fall over in the driveway. I'm thinking front nosecone and the fairing's frame in particular, tho it could be straightened fairly easily.
