The faint redline now appears at 12,500 rpm, reflecting a 1,000-rpm increase from the F model thanks to improvements that include a higher compression ratio (11.6:1 versus 11.4:1), redesigned piston, revised cam profile, and dual ram-air intakes. Honda says the updated motor develops 5 percent more power above 10,000 rpm. American Honda doesn’t quote official power figures, though in other markets the CBR is claimed to put out 94 hp at 12,000 rpm and 47 pound-feet of torque at 8,500 rpm. The acceleration doesn’t feel like there are 94 horses rotating the front sprocket, but it’s still plenty fast to have fun with, and slipper/assist clutch makes it easy to enjoy what the motor has to offer.
