Hi there, Can you please give me a price for; Headlights Front Cowling thanks, scott

This is a dealer item...call your dealer for a price quote.

Check out a forum for the bike for example www.r6-forum.com and ask the members on there if anyone is selling the bits you want.
Motorcycle breakers are another good place to get bits from, if the bike has had an engine fault, you may find the front fairing and headlight aren't damaged.
You could also try the dreaded ebay, careful when buying headlights that they suit the side of the road you are riding on. i.e. if you are a UK rider, then Euro headlights dip to the opposite side and will not pass the MOT.
To finish, these bits are one of the first bits to be damaged in an accident so command a premium price as they dont stick around as second hand items.
