I agree Yamaha's two-strokes are over-priced, given the technology in them. But I think they are approaching it differently. Rather than giving it a price to fit the cost, and then seeing how many bikes they can sell, they are setting a number of bikes to sell, and that's determining their market price. It's obvious that they're under-producing these machines. That puts them in a different category from the "cutting-edge" stuff like the 450Fs, which I don't think are too expensive given what they are. Maintenance, of course, is where the four-strokes really burn the riders, as we all know.
