Get your facts straight bro .... Kawasaki is always be on better side ,Due to more dispalcement of power in the relevent catagory area!
Also more HP and Torque is the thing which makes bike throttle response agressive !
Here you go with the specs link :
2013 Kawasaki Ninja ZX-6R ABS vs 2013 Yamaha YZF-R6 in Motorcycles
P.S I am not the supporter of any of the above mentioned bikes .... Even If I get my hands on any of the mentioned bike ,I will be more than happy
