I have a modified ZX14, full exhaust, filter, ECU flash and risers and a 2014 Ninja 1000. Power wise the 1000 feels like a moped compared to the ZX14 to me. Don't get me wrong, the 1000 will get up and go but I have to really give it the throttle and rpm to get it going compared to the ZX14. I can just bump the throttle in the ZX in 1st, second to only 6-7k and hit tripple digits before you realize you are going that fast. On the highway the ZX feels better, more stable and less wind on you. The seat also feels a lot more comfortable on the ZX. As for the 1000, I would say it is a little more nimble in the corners and has a more comfortable handle bar height. I can do 250 mile mountain rides on either bike with the limiting factor on the 1000 being the factory seat and riding position the limiting factor on the ZX. I think with a Sargent seat the 1000 could be an all day any mileage riding bike. To sum it up, the Ninja 1000 has smooth predictable power through out the rpm range and the ZX14 has a violent power delivery after the secondary throttle plates open fully with more power than I care to try. I could not imagine full throttle 11k rpm on that bike. It is more fun to drive though unless you are in really really tight curves like on the Tail of the Dragon then it becomes work. I plan on taking the Ninja 1000 there this year.
