VEry popular in the USA for historical reasons, but still you can get one restored and rebuilt over there for under $5k. HAve looked at a few over the years but never dont anything.
So over here i would have thought even $5k was top dollar and more so cause its here and ready rather than the import thing. Also not the historic buy, morsoe the nmice to have, very few tracks you can actually ride em on too, our DT bikes dont like these right handers and long tracks that much so from a race point would also lack any real special advantage value.
Dont get me wrong, love to own one, but ummm at that price i can think of 3 other bikes id rather have that would total that.
