Based off the existing ’12 ZX-6R Inline Four engine, the 2013 configuration makes use of the same bore (67mm) but a 2.6mm-longer stroke (45.1mm). A number of other enhancements were also made including updated cylinder head porting and camshafts. Refinements were also made to the intake and exhaust systems to work with the new engine spec. The design of the wet-style slipper clutch is new as well.

The chassis received some love highlighted by the use of a new Showa big piston fork that features separate function technology similar to what Team Green employs on its 2011-plus KX250F motocrosser. For the sportbike application however, it uses springs in each fork leg but preload adjustment is made on the left leg while compression and rebound damping is handled on the right side. The ZX-6R also gets new monobloc-style (machined from a solid piece of aluminum for added rigidity) radial-mount braking calipers sourced from Nissin.

The ’13 ZX-6R is the first Japanese middleweight to offer traction control. Derived from the systems used on the Ninja ZX-10R and ZX-14R/Concours, the electronics offer three levels of adjustment based on road conditions or rider preference. Two different engine power modes (Low/Hi) are offered. The shape of the body panels has also been revised for more efficient aerodynamics. The improvements come at a substantial cost with the 2013 ZX-6R costing $1400 more than this year’s model.

This should turn out to be an awesome performer but one problem I see is the body panels. Where I live a big rig can pull 75 legally and with all those voids I know well that bike will start dancing at 200ft on approach to the rig's dirty air. One day these engineers will understand we ride on the hiways not the track and as such are forced to deal with adverse dirty air. Come up on that rig at 100mph and things get interesting for the run through it's wake of trashed out air.

Probably another capable performer, but with typical Japanese styling - way overdone with panel breakups and colors. I'll take my MV F3 anytime, everytime.

So many negative wannabe business analyst! Good looking bike. I want one.

@ koko46 - The 2012 Honda CBR600RR has a "wet" weight of 410 pounds. Not sure I get this bike - if Kawasaki is going to make it too large to be a super-sport, why not bump up the displacement to 749cc to compete with the Suzuki GSX-R750?

Traction control should be useful on damp,wet,sand/gravel, broken pavement etc. Don't know why people think it wouldn't be valuable on a two wheeled machine, wish I had it on my bike.

Is this bike really coming with a 190/55 stock?

@Gary22, I read that they are making a 600cc bike for the Japanese market. I don't know how that will help anyone racing here in the states but it will be on the grid in WSS.

Will this bike be able to compete in the 600 cc racing class?

Well I am glad that this bike is out as i finally think kawasaki has made a good looking bike. My new favorite supersport although i don't think the traction control is necessary for a 600 although you can make the argument that it can be turned off. Just a quick question at a curb weight of 423lbs does this make it lighter than the cbr600rr which is the current lightest supersport?
