Just supposing the other half allowed it (which I doubt but let's dream), what bike would you permanently park in your lounge/living room as an art object? You know, something that totally captivates you instead of watching stupid Corrie.
I mean a bike that inspires you , one bike that sums you up so much you can't take your eyes off the shape. You get the idea.
My choice - 1980 Honda CB900.
(Doesn't count but the CB250NB Deluxe was second on my list. Oh how I remember those Com Star days. So can't include the Ducati 916)
