Here's what a stock R6 08-09 looks like. Note the gray side/accent plastics (with decal on it, but the base plastic part is gray), the placement of the Yamaha logo on the lower fairing, the placement of the R6 logo, the color of the front half of the tank.
Now, someone might have painted some parts white, but why would they move the R6 and Yamaha logos?
What's more likely, someone painted the gray stuff and MOVED the logos around, and kept the stock rear fender and the side markers, OR this bike has been significantly rebuilt?
EDIT: oh, I see black cx's post now. The advertised bike is a '10 I guess. There is a discrepancy between model years sometimes when buying these bikes; something like even though it's a '10 model when built in '09 they have to sell it as an "'09". (contrary to cars.)
Also, the R6 is a great bike, but not for commuting.
