The 2013 Kawasaki Ninja ZX-6R is set to return to a 636cc displacement, according to a spreadsheet released by the United States Environmental Protection Agency (EPA). With alleged spy shots of the new ZX-6R already hitting the press, the supersport-class bike noticeably takes a design cue from its liter-bike counterpart — a move that should surprise no one.
Listed by the EPA as making 129 hp (96.4 kW) at the crank, the move to have the 2013 Kawasaki Ninja ZX-6R be a 636cc displacement machine is interesting, as the EPA’s document does not list a 599cc Kawasaki Ninja ZX-6RR analog, something the Japanese brand did last time it bumped its middleweight’s displacement figure beyond the norm.
Not a true 600cc-class machine, Kawasaki will have a hard time racing the ZX-6R in any proper supersport class here in the United States, though we doubt it would be hard for Team Green to get the bike homologated for AMA Pro Racing’s Daytona SportBike class mash-up, but that’s not saying much.
Other pieces of information gleaned from the EPA’s document is that the 2013 Kawasaki Ninja ZX-6R has a 13,500 rpm red line, optional ABS, four-cylinders, and four-valves per cylinder. Expect the new 6R to debut this fall, at either the INTERMOT or EICMA show.
