As the speedo ticked past 165 mph, self-preservation took over and we jumped on the brakes as turn one rapidly approached. As amazing as this was, it was only the first flying lap of what would end up being a full day of riding the most impressive motorcycle we’ve ever tested.

Monobloc Brembos, forged Marchesini wheels, fully adjustable Ohlins suspension—all there. But if you still think it sounds more palooka than prizefighter, let's step outside for a minute.
