Hey Nippon that sounds really exciting keep us posted. Where is it to be manufactured?
I talked with a British builder who makes the ducktail seats and covers, sells some of them on eBay, the rest through his distributors (I don't know who those are, though). He is bringing out K1-K3 seat foams now, too, for riders like me!
Those haven't been available for so long that I had forgotten how good they were. They are slightly wasp-waisted where yours thighs go down when standing, and the seat cover was scalloped in the same area with the bead going down along this line, so your pants did not wear it so badly.
By the K4, this became the "platform" seat, with the bead just following the top of the seat contour, to protect the paint on the side covers by pushing your thigh outward a little while standing (so suggested the Honda rep at the time, anyway: paint wear on the tops of the side covers had become a warranty issue).
Being a Honda wrench at the time, I immediately noticed this on the K4, making it feel almost as wide as the K0 with those squared-off side covers that made Honda dealers measure your inseam at the time of sale in 1969 and 1970 (minimum 30" inseam, or you could not buy a 750K0, honest! At least, in Illinois...).
