I replaced the stickers on my 2006 XTX a while back and it was around �30 for the stickers for EACH panel. So �60 all in. I ordered them through my local Yamaha dealer who order them directly from Yam. The circular, embossed tuning forks logo is �7. For ONE!!!
Have a look on eBay for those logos, you can get a pair of Gold or Silver for about �3.
