1973-75 Kawasaki Z1 900
The days of the traditional British café racer must be numbered by now, and we’re seeing fewer machines adorned with checkered stripes and fork gaiters. The ‘brat style’ is taking a lower profile too, with builders dropping the glitter paint and hunting down Dunlop K180s for an authentic tracker look. There’s a renewed emphasis on performance—but not the clinical, metered-by-electronics performance of contemporary sportsbikes.
