I'm not American, so don't quote me, but I remember someone on the site mentioning lemon laws, a couple of years ago, & the reply was that it only applies to cars, not bikes. I hope I'm wrong. Good luck.
Just did a search for "lemon laws" & it brought up a couple of answers. Try it & see if it's any help to you. However, your lawyer friend will probably be MUCH more knowledgeable than any of us. :2tup:
