A spreadsheet from the United States Environmental Protection Agency listing 2013 motorcycle certification data includes information about new an all-new Kawasaki Ninja 300 and the Ninja 400R, while also confirming reports the new ZX-6R will return to a 636cc engine displacement.
Appearing on the EPA's spreadsheet doesn't necessarily mean these models will be introduced to the U.S. market however. The Kawasaki Ninja 400R was included in a similar document for 2012 but was never introduced. The 2013 document does not include a Ninja 250 (pictured above) which was recently updated for other markets, so it is likely to be replaced by the new Ninja 300.
According to the EPA document, the 2013 Kawasaki Ninja 300 will be powered by a fuel-injected 296cc four-valve twin-cylinder engine. Power is listed at 29 kW (which translates to 39hp) at 11,000 rpm.The documents lists both an ABS and a non-ABS version.
