You really don't have to do a darn thing, the dealer computers will show the date the bike was sold originally and the miles on the bike will be obvious.
Just for future reference:KRG said:Hello,
I am wondering if anyone has experience transferring the warranty from one owner to the next.
One of my friends is selling his 05 749 Dark to my OTHER friend. I am trying to help out a bit and find the information on transferring the warranty over to the new owner.
Any relevant help is greatly appreciated.
