The rumor mill has been rife with whispers that the 2011 Kawasaki ZX-10R could meet or exceed 200 horsepower. Well, that number was looking to, in all actuality, be a still-screaming 197 hp…until the EPA intervened.
The Environmental Protection Agency has regulations governing not only typical atmospheric pollution, but noise pollution as well. This is governed under the EPA Noise Control Act. In unmodified spec, the ZX-10R did not comply with EPA regulations. How Kawasaki allowed this unexpected turn of events to occur is unknown. What has been confirmed is that the ZX-10R rev limit will be lowered by 750 RPM for US-destined models.
Currently, it is unknown how much this RPM reduction will affect peak horsepower. Of course, the aftermarket will surely – and quickly – respond with ECU modifications which will override the OEM rev limiter.
