Lemon laws rarely help with that kind of mileage. Based on what most consider to be the life of a motorcycle, his bike has had about 4 lifetimes already.
Unfortunately, it's almost impossible to say which failures were a result of original p-poor quality, and which failures basically resulted from p-poor repair work by the dealers. But I'm willing to bet that many of those repeat failures were a direct result of botched repair attempts or overlooked problems during repair attempts. It's one of the big reasons I'm so outspoken about Harley's constant failure to get stuff right the first time. Sure, there is a warranty (if you can get them to honor it). But invariably whenever I've had warranty work performed I've had subsequent failures, and eventually I just fixed the crap myself. So to me the warranty is fairly meaningless, and the actual quality and reliability of the original product is by far the most important consideration. Style and "the sound" don't get you down the road and back home again, quality and reliability does. Serious riders should think about that before making their next purchase.
