The specific inspiriation is choppers of the ‘60s and ‘70s. A key element is the ‘peanut’ 2.2 gallon tank (filched from the Sportster 48). After that is mostly predictable ingredients: a 21-inch, ‘skinny’ front tyre, lowered rear end, high bars and lots of chrome. But where Harley’s pulled it off for me is by going the extra yard with the details: the sexy white walls, the circular air filter cover (which reminds of Harley’s big twins of the ‘80s), the fab graphics and logos and, the masterstroke, the ‘big flake’ chunky metalflake paint.
