Up to about 15 years ago you always saw at least one a day in London.
What i mean is a guy ( not a Hells Angel necessarilly ) on a scruffy ancient lightly chopped Triumph,Harley or cut down Kwacker, cut down rear mudguard - nunberplate on side, ape bars , painted matt black or summat.
They would be wearing the smallest lid you’ve ever seen ( like a bicycle helmet ) , jean jacket with ripped sleves and leather jacket underneath, tons of chrome bog chains, confederate flags, skulls, Iron crosses all over the place - motobike chain slung over their shoulder.
Maybe thats where they moved to - an elepheants graveyard for Ratters.
…I did see one about a month ago now I remember it ( well almost he road an old BSA Thunderbolt, oily and unmodded ) not quite the chopper rider though…
