So, maybe I'm retarded, but why are the speedos inaccurate from the factory?

That just seems like a liability for Kawasaki and I can't think of any logical reason they do it, but obviously there is because they do it.

On a side note, or I guess more on topic haha, you guys are a bad influence. This thread is making push my top speed. Hit 149 today (without a speedo healer).

Don't have a clue. New car speedos are extremely accurate.

I think they're under the mistaken impression that it will keep us alive, as maybe we won't ride as fast if we think we're going faster than we are. This is, of course, completely retarded.

i did an indicated 176. Yes I know no one will believe me because it wasnt there bike but it was on a cold dense air 50 degree day. k&n filter full micron/yosh system jumper mod, gas tank on e and throttle pinned. I am sure my speedometer is off but im sure its more of a true 164-166

6R,191MPH.....what internal mods can be done?

 

[JBear]

Bored, stroked, ported, polished, knife edged, lighter materials, treated parts, gasket swaps, bumped compression, yadda yadda vroom vroom...

 

[MegaBytesz]

^^ I'll add more, Cams, Pistons, Head, Crankshaft Rods, Crank, Gears, CCT, Valves, Clutch, yadda yadda vroom vroom...

True, but what fun is that....

157mph with my backpack on. no speedo healer so not sure how accurate it was. I've done mid 70's in first. Never really tried to see first gear top speed.

i just did the -1 front on my 05 zx6r,the other nite i was riding w a group of friends and i put it in 6th and held it wide open.it said 174 all 5 times that i looked down.i way 205 in full gear.this was on a cool nite on a long flat rode.all i have is a modded stock muffler and the -1 frnt sprocket.

 

[Markao20]

Since i have fitted a full system had a power commander set up and smaller rear sprocket i pulled a true 172 as i have a speedo healer fitted

Here's a spreadsheet that shows mathematically that the top speed of an 07-08 ZX6R completely stock is 183 mph at the 16,500 RPM redline.

It will actually probably be less because even with high tire pressure, your rear tire is going to deform a small amount and reduce the distance between the axle and ground by a small amount. And if you also consider a small amount of tire slip you're probably around 178-180 mph.

Of course this is theoretical because a stock ZX6R doesn't make enough power to push it through the wind at 180 mph. Seems like most people hit between 160 and 165 mph depending on rider weight.

Finally hit the rev limiter in 6th earlier tonight... managed a sweet 161mph. I've never seen lines fly by me that fast, it was crazy!

Cool, what track were you at?

 

[Ibz]

I don't need to tell all you guys to ride safe. I have not been to the track yet but my bike has, its a track bike I bought off a track guy. The bike tells me to give it more all the time. I hit top speeds only once in a while on the local, almost always clear highways here in N.S. It's the mid range of this bike that im most impressed with.

Last summer on the 91HW in Riverside I hit 159 before I had to slow down, seems like I had a little more in it... and my bike was stock.

 

[Luwi Kawasaki]

Theres a video on you tube where a zx6r p8 hits 281kph on the autobahn, which is 173 mph.

 

[JBear]

If I had a video camera, I could easily make a video for Youtube with my 10R hitting 300mph on the two lane road outside my house.

Buddy of mine was in an accident with his '95 Cobra. He had a 150 shot hooked up in the trunk. Accident wasn't his fault, and he would have been fine. Thanks to the NOS, he left the scene in cuffs. They take it very seriously around here.

Why would he leave it hooked up? It only takes a couple minutes to unhook

 

[JBear]

He was a street racer.
