Honda Blocking Saisei from stocking seats /covers

[AshimotoK0]

K2-K6 that's a pic of the pre-production 1969 'Brighton Show Bike' and the seat profile was different than the production bikes including the sandcasts. It was much flatter. I think Yamiya do do a flat profile seat in addition to the 'standard' one. It also had single pull linked carbs and a black stripe on the tank trim like the K1
