Sure you can...for around $900...seriously. Rear fender is about $350, front is around $300, radiator shrouds are about $200...etc.
UFO seemed to me like the best choice in quality (besides stock), but the colors are limited (white, black, blue). Maier used to make kinda bad looking plastics (no shine, almost textured finish), but now they appear to be pretty shiny and they make lots of colors (including orange and black).
I looked on the Yamaha website but no luck...I'll go look some more.
