It'll be all white on the night - WHITE CB400N-D

Unfortunately not UK, I think it was perhaps Australia.
The UK Honda dealers at that time, late 1983 &84, were rolling out the VT250FD & VF400F, so although the 1984 ND is listed as an official UK model, I don't think anyone in the UK has posted that they actually had one, new, from the show room.
I do love that colour scheme of NH-111 Cortina White (the same white that was used on the VT250FD), and I shall dress a 250/400/450 using that colour scheme some day  .
The colour works very well with your Gold wheels.
If I were dressing one (or two) up I can't make my mind up if it would also work with black wheels, though I think black wheels may go better with the red ND colour scheme (like CTB's one), my indecision continues...... ....
