The reason it's such a big deal is because Harley's don't do this sort of thing, which is pretty pathetic. I'd say 95% of Harley's sold live pampered lives with heated garages, covers, and constant attention. On the flip side Japanese bikes tend to be ridden hard and put away wet, raced, abused, and actually used like a motorcycle should be.
Also Japanese bikes have been doing this sort of thing for what 30-40 years, also most bikes they build we made better by competition. I tell you what, when they do this for 10-15 years I may give them some respect..
Oh yea, I started racing motocross when I was 14, I'd say that's challenging, no??
