It WONT be cheap
It depends on if you want OEM or aftermarket. OEM Plastic was cheapest from Yamaha of Troy. That is were I got my 2006 Black Metalic Plastics. I ordered the 2006 LE stickers from Ronnies. Bike Bandit would be onther good place to get them from.
Some of the stickers were 70 bucks a pop. Plastic was 450 shipped, and the decals were probably around 375. I wanted my 97 to look like an LE so I went with OEM.
