My brother owns the 2008 ZX-14 special edition.
We went on a trip (100KM) and stopped for an ice-cream. He asked if I wanted to ride it. I finished that ice-cream really quickly.
I'm not going to lie; if you're power hungry the ZX-14 is your best remedy. It's the most badass bike I've ever ridden. It's just pure power. All the parts are really tight, because even just placing your hand on the throttle will cause it to accelerate.
The good news:
1) Pure power.
2) Looks so badass it scares people.
3) They don't call it a Ninja for nothing; the bike is hauntingly quiet.
4) Stops NOW! Just placing your hand on the brake-lever makes the bike STOP.
5) VERY EASY to service. Coolant, battery and oil changes are in their own "shelves." That's right, you unscrew a hatch and there's the section you want. It's ingenious. R1 oil-changes are a pain in the ass.
6) The only mod you want is bracket framesliders. That is all.
7) 300 KM/ hour and VERY STABLE at that speed. (Yes, we dragged it).
8) Don't underestimate the handling. Even with the long swingarm, it still has FANTASTIC handling. DO NOT RACE A ZX-14 WITH AN FZ6 - YOUR CHANCES OF WINNING ARE VERY SLIM. EVEN IN A 10-TURN RACE. It's the frame, tires, forks, suspension, brakes...the list goes on and on.
I've ridden both bikes; trust me.
Now for the BAD NEWS:
1) The bike gets really hot really fast.
2) The ZX-14 is a pure afterburner. BINGO FUEL!!
* The fuel consumption is only a little bit more than an R6...
3) Insurance is very, very, very expensive.
4) You guys complain about the 1st-gear "clunk" on an FZ6??
------The ZX-14 has a 1st-gear CRUNCH. It feels like stomping on a skull. I'm not kidding. It makes the most grotesque CRUNCH from Neutral to 1st gear. Gah! I'll never forget it.
5) Although all the lights are automatically flushmounted, I have a feeling there's something bad about that...don't know what it is...just a bad feeling.
6) The 2008 special edition is not a gloss finish...it's matte. It's really difficult to clean. Looks cool though.
There you have it. I hope this enlightened you.
