Just curious about the top end of the Z, although I'll never get very close. I've seen it posted, I believe, that the Z will top out around 150. Is this correct? I've noticed that the full-on repliracers that displace the same as the Z can run up to 175 or so, depending on which bike. What's the difference? Is it for lack of a fairing . . . aerodynamics? Is it because the Z engine is slightly detuned and biased for good midrange and torque? Or does the Z just run out of HP or gearing?
Inquiring minds want to know . . . so does my IBM (itty bitty mind).

my '03 can hit 150 with a +3 rear sprocket before it runs out of gear, so with the stocker on there I'm thinking maybe155-160? It is because of all of those things you mentioned. Less hp, lower gearing, heavier and less aerodynamic. Who really cares though when 99% of your fun is had at less than 100 mph? You're back will appreciate the z more, that's for sure.

I suspect you're exactly right on all counts. Nice to know it will pull redline in top gear (even with the +3)
Thanks.

i agree. my fun is zero to 100. but i also like to cruise at 70. as soon as my pipe comes i'm going to a 16 front to lower cruising rpm not for more top end.:eek::eek::eek:

so far mine has seen 135mph and still pulling but running out of steam. it's seen 126 in the 1/4 mile, so i figure it would top out maybe by the 1/2 mile mark. my 2006 r1 has seen 168 mph with room to spare, but that is apples to oranges. advertized at 150-160 mph i think so. have fun testing yours.

Yeah, mine starts to run out of steam at about 135. 140 to 150 takes a while.:D That's speedo speed, but I have a speedo healer on there that makes it pretty accurate.

I know this because I got tagged by a cop when my speedo read 115.:eek::eek::eek: When he walked up to my bike, he said I was going 115.

No ticket though because I was trying to get away from a swerving drunk at 230 am. Lucky too because 100 mph and over is an automatic license suspension for 6 months here in MN. I know this because I got clocked on my '77 cb750f at 101 last year.:(

i think my 2010 will hit 150 easy now had her to 140 the other day by accident. pulled out to pass a couple of cars on a short straight stretch. down shifted to 4th on pinnned it to get by quickly bythe time i hit 6th glanced down saw 140. looked in my mirror and my buddy was on my tail on his cbr1000rr. couldn't slow down sow eased over to give him room then let off. was still pulling very hard. no loss of steam. stock gearing so far, still ahven't put my 16 sprocket on. maybe next week. oh, by the way i like to have my fun at 100 or less. not changing for top end but for less cruising rpms.:screwy::screwy::screwy:

Does anybody know the top speed of the new ninja1000/z1000sx ?
I was just reading a review on the new ninja (sports rider mag I think) and they said that because of the gearing differences that it has a little bit lower hp rating then the z1000. Also said it lost a little in the midrange.

I know that with 15/42 gearing on a first gen, a couple of people have reported hitting between 155-160mph on the dyno. Of course many other factors come into play when you actually attempt it riding the bike...

I've seen 137 on a short burst still not fully broken in yet,but seems to be making more power as its breaking in.
Dont know what the rpms were was watching the road not the instruments,if you know what i mean.
Just glanced down when i let go of the throttle.
I think it had at LEAST another 15 to 20mph in it.
It was pullin like a freight train!

hey, barry did you change your redline when you added tuner. also did tou change gearing yet. it would seem the rev limiter would kick in at the same rpm so top speed would actually be the same as stock. just would get there quicker and easier with the added hp.:screwy::screwy::screwy:

Hit 170mph on stock gearing. No speedo healer so probably closer to 155-160.. Never again.

No point in going that fast. I plan on changing the gearing also when I change chain/sprockets in a few weeks to give me a lower cruising rpm and better MPG!

28K miles on stock chain/sprockets..

:lol:, Yeah that's pretty fast on a bike with hardly any wind protection.
