As far as Jap(anese) bikes "having no soul", "not as cool", etc., etc., that (to me) is as offensive as calling them "Jap" bikes. It shows just as much prejudice as the typical HD rider (although I have a bunch of HD riding friends and don't take it personally).
I've owned 165 bikes in my lifetime, and almost half of them were Jap(anese). The "ONE that got away" was a "Jap" bike, a '74 Honda CB550 Four that I refurbished, then restored, then totally customized as a cafe racer. I poured two years of hard work into it and rode it more miles than almost any other bike I've owned. I street raced it, toured on it, and even rode it off road a few times for fun.
It had more "soul" than all but a handful of other bikes I've owned, a few of which were Brit bikes, a few of which were Jap bikes. I didn't have the forethought to hold on to it, but traded it in with 4 other bikes to buy my 1980 KZ1000 which I still have, and which will be one of the last bikes I sell. IT has "soul", too.
I believe the "soul" in a bike comes from becoming intimately involved with it, by working on it, riding it in some memorable times, or a combination of both.
A motorcycle is just a machine.
I don't think there are 2 more people in the world that detect the "soul" in any of my bikes, the way I do. Nor could I detect it as easily in theirs.
