Duke’s Den: The WFO Nut

The ’06 10R scaled in one dozen pounds heavier than the previous year, and several of those were placed up high and rearward – horrible places on a sportbike – in the form of a then-trendy undertail exhaust system. But the ZX-10R was no slouch, boasting a whopping 155 rear-wheel horsepower at 12,000 rpm. This is me from the ZX’s domestic launch at California Speedway.
