Original CB 750s, depending on the model, sell for between 10 and 20 grand. Wonder what that's worth now....
Tbf, although I gave it a "WTF" rating, that looks like something I would have built about 10 years ago as I do love a bobberfighter (900SS owners look away now)
Ahh... for me it's the seat/tail unit that let's that particular build down. A good motorcycle design/build needs good "conclusion to the story"... the tail unit is important! XTR Pepo is a good example for getting things right...
It's more problematic than the tail, the proportions are all to whack. The rake is too steep and then the rear swingarm too long.
