The Honda CB900F was respectable forty years ago, but today it?s outgunned by sportbikes that are lighter, quicker and better equipped. But what if you gave the venerable CB new running gear and a bored out motor" NCT Motorcycles have just done that?and modernized its looks, too.
This 1980 model Honda CB900F arrived at the Austrian shop with a concept from its owner. He named it ‘Black Swan’ after the black swan theory: a metaphor for something unexpected that has a big impact.
