Anyone?

I don't actually know, but I would doubt that it is much better than stock. Kawi knows the 300K cut-off, and has probably set the motor, transmission and so on for the best performance to that speed. I would be interested to know what the bike would do with small changes to increase speed (ie no nitrous of supercharging).

Well, I've heard rumors that the time machine from Back to the Future has been revamped, but can only be achieved by using a zx14

I did a certified 190.8 mph in the standing mile at the Texas Mile in 2010 on my 2007 stock motor with full Yoshi system and a power commander. (unrestricted). And At 6'5" 239lbs I am not what you would call aerodynamic. LOL. I think my 2013 ZX14R will do at least 200 in the mile. Top end is really dependent on gearing. The new ZX14 has more displacement and more horsepower. If you switch the stock exhausts out to a titanium Brocks system and get the ECU flashed/ delimited. (Ie..Timing advance in first four gears restored and secondaries opening in a linear fashion to the primaries) and add the PCMV with Brocks map like I did you should have NO problem! I probably dropped 45 lbs of weight just switching the exhaust. The Brocks system only weighs 8.4 lbs. The stock system weighs a good 55 lbs

My problem is keeping a rear tire on it more than 1500 miles

I put on a full TI Force titanium 4-2-1 and weighed both the TI Force and stock systems the weight loss was an even 30 pounds for mine. The bike is a 2006 ZX14 I got 8 years ago used, it came with the TI Force system and Ontario set up power commander both new in the original boxes. Ontario had a dyno and checked stock at 165 hp, with pipe and power commander it was 185 hp. These are near sea level numbers at the rear wheel.

About 160 for me.Hard to see at that speed.6 foot 2 and 270lbs is hard to squeeze behind the screen.Fast enough for me.

I re-calibrated my Speedohealer the other day and came across this little gem:

"For 200 mph runs, set the Speedohealer to -99.99% correction factor"

Tried it (the reset, not the gonzo run) and the speedo needle wouldn't even move. Apparently, as long as the ECU doesn't sense you're approaching 186, no limiter kicks in.

You can set it at 50%, so you just double your speed indication to get your actual speed. That effectively defeats the speed limiter too since there is not much chance of going 372 mph to kick in the limiter showing 50% speed.

I hit 203.00418 on my 2009 Monster with an SS head 48 MM throttel bodies and a 30 shot of NOS. Last year I hit 190.26 with no NOS....So maybe it would be around 188 to 192....My baby puts down 206 RWH

well, fastest on my old VFR was 151 mph.\

fastest in my camaro on the highway, GPS verified was 175 mph, that was rock solid! that was only in 4th gear, lol!!!

this bike really makes my old VFR feel like it was a toy.

I dont know the answer to your question, but you know it will be over double the posted speed limit, fastest I have had mine since installing the SH.

De restricted with a ECU flash and a taller gear( and the balls to hold the throttle wide open) the new ZX14R will easily do over 205mph! With enough real estate you could probably hit 210mph with a three tooth smaller sprocket on the rear. This bike has the torque and horsepower to pull a much higher gear. my old 2007 did 190.8 at the TX Mile back in 2010 The newer model is much more powerful!
There is no replacement for displacement! 98 more cc's, bigger injectors and throttle bodies with stronger rods etc. All add up to more power! :crazyloco

someday, I shall find out for myself after I've lightened it up a bit and done a few lil things. one of the reasons I got the Hulk... to get my 200+ license. hopefully I can do it without a turbo. I'd like to keep my bike as close to stock as possible without adding the really big power adders. if need be, guess I could add NOS just for the run. But would rather do without. can't wait.

on a sidenote, is the 14r unstable at high speeds? my busa was rock solid at 165. so far, not that I've gone that fast on the Hulk, but the Hulk has been smooth as glass up to 130 approx...

as far as having it hard to hold onto, sounds like too many weak handed folks. LOL they need more alone time. LMAO. j/k

14R is definitely smooth as glass at speed.

I've only had mine to 152, but it was still pulling hard. Lowering and a damper help high speed stability a lot, but even stock it had no drama.
