That fat rear Dunlop delivers the goods, too. Putting 161.9 horsepower on the pavement at 11,750 rpm, it dethrones the previous dyno king, Kawasaki's ZX-12R (161.4 at 10,000 rpm). Anyone else want a piece of this? The ZX-10R overpowers Suzuki's Hayabusa (156.1 at 9500 rpm), Honda's new CBR1000RR (153.3 at 11,250 rpm) and Yamaha's latest R1 (158.3 at 12,500 rpm). And here's the kicker. Add that 433-pound wet weight to the 170-pound rider we use for spec-chart calculations, divide by 161.9 horsepower, and you have a weight/power ratio of 3.72 pounds per. It just doesn't get any better than that, sports fans.
