An EPA document listing motorcycle emission data for 2013 has revealed details of the new, American market-oriented Kawasaki Ninja 300 and a return to 636cc capacity for the 2013 Kawasaki ZX-6R.That new Ninja is powered by a 296cc parallel twin developing 39bhp at 11,000rpm, a marked improvement from the current model’s 31bhp figure and significantly more than the bike’s closest rival, the 26bhp Honda CBR250R. The 30 is fuel-injected, also a welcome upgrade from the carb’d 250 that’s been sold in the US.The new, 636cc ZX-6R will make 129bhp, which should make it the most powerful “600″ on sale next year.We’ve previously seen spy shots of the 2013 Kawasaki ZX-6R and the 2013 Kawasaki Ninja 250 was just officially unveiled. It’s likely the 300 will ape that model’s styling, because there’s no tiered-licensing laws in the US, Kawasaki is free to punch the engine out for a little more power. Recently, the CBR250R has captured more than half the Ninja’s market share; it was previously the 5th best selling motorcycle of any type in the US.The Ninja 400 has been listed on this document in previous years, but hasn’t been brought to the US.
