some bike like suzuki have retard built in in 6th gear. that limits them to 186. even without them. none of current bikes will go 200. yamaha is not speed limited but gearing,hp, aero will only allow 183 or so.

I don't believe that is true. Not long ago I saw 189 on my 05 R1 (indicated of course), but it was still climbing pretty steadily up until it felt like it hit a brick wall at that point. It either cut out fuel or electronics, couldn't tell which one. If it were aerodynamics or gearing that were your only limitations, it wouldn't stop that suddenly. Instead you would gradually reach whatever the top speed is.

On the other hand, if you're saying these bikes are kept from reaching more than 183 mph (actual) due to aerodynamic or gearing limitations, then yeah I can see that.

 

is there a "certain" specific speed that all bike are limited too? Or is that the 186 you were referring to? O and one more related question while i'm at it. Isn't there a limit on HP per liter on all automobiles in the US? And does anyone know if the european bikes have the fuel or ignition cut at a certain speed, i only ask cuz i know they have the autobaun and stuff. No fuel cut defense electronics out there to combat ur top speed if u were to want to go like 200+????? Big thanks to all who reply

 

My 2005 R1 is not electronically limited, unless you call a rev limiter a speed limiter. My bike, completely stock, continues to accelerate past an indicated 186 (the speedo stops reading at that point) for at least another 1500 rpm until the 14000 rev limiter. People that say it won't go any faster than an indicated 186 probably haven't actually tried it.

Having said that, I have only been able to do that in the right conditions (no headwind and probably a tailwind).

 

My Gixxer is certainly limited to 186. I've tried it myself. It rips up to 186 and then comes up against a smooth limiter. There was certainly more to come from the bike. My buddy has a K2 with a de-limiter on it and he has had his bike into the high 190's . But thats indicated speed not true speed of course.

I can confirm this for a fact... I have done it at least 3 times on the 05 R1 and everytime she will run right up to 189 nice and steady then bam no more... If it where reaching a top speed due to wind resistance gearing etc wouldn't it slowly climb a tad then stop? Whereas this is like a sudden stopping point of 189 indicated.

Edit - This of course is by no means an actual 189mph but I think this thread is running on indicated speed since he said the GSXR stops at 186mph and that is their indicated speed limit from the factory.

 

Speedohealer is needed for precise readings i believe.
;p

 

Due to fear of the government limiting/banning sportbikes, in europe the manufacturers had whats known as a "Gentleman's Agreement"

No stock motorcycle will go over 186 mph, limited from factory.

This is due to the high speed wars of the hayabusa and zx12r. Thats why the new zx14 doesn't make any claims of max speed, and why they stopped saying "fastest production motorcycle" in advertising.

im not talking bout the speedo.. it will only go to and stop at 189. im generally refering to actual speeds with gps, and not dyno either.

BUT WE are talking bout bone stock bike right off showroom floor... bone stock R1 with stock gearing and exhaust.. nothing touched on it period... wont pull to revlimter in top gear...and its not electronically stopped. its the bike wont pull any more RPMs with the stock exhaust and the aero of bike. now we can adjust this with gearing, pipe, pc3 and whatever... but for manufacturers they have to make it so that as you buy it, it will meet requirements... now what you do with it when you get home.. well thats up to you.

Actually, it will. But like I said before, it won't do it everytime which leads me to believe that I probably had a tailwind or at least no headwind. It will pull all the way until the 14k redline

 

I too can confirm redline in top on a stock bike.

 

When it cuts off like that you're hitting the hard limiter which is there to protect the engine..Not to limit your speed...It should do that in every gear if you rev it too far.


I know some people will see higher numbers than 186 on their speedos...Their speedos are off and they are actually going slower...The true top speed of the R1 is somewhere in the low 180's (or high 170's)depending on the conditions and how heavy the person riding it is...

Simply put a stock 1000cc bike will not see much more (if any at all) than a TRUE 186 because there's simply just not enough HP/torque..I know of a few guys on ZX10's that have seen 189 or 190 on GPS but I think they had exhaust and fuel mapping mods....

The ZX14 and Hayabusa do have these restrictions in top gear...If they were allowed to run up to their redlines in top gear they will run over a TRUE 186 mph..these bikes have enough torque to do it but are not allowed to because they want to limit the speed..

This speed limiter is not the same as the limiter you have at redline that cuts the bike off to protect the engine...The one on the ZX14 and Hayabusa is an actual speed limiter programmed into the electronics.

To bypass the speed limiter on the ZX14 and Hayabusa you can install a speedo healer and set it to read much lower than the actual speed and depending on conditions/rider weight you should be able to get into a TRUE 190's.

 

I will spare the lecture on just how dangerous going that fast on the street is.

It is easy to program the stock ECU to limit the top speed of the bike in any number of ways. Whether it is remains a secret, but it wouldn't shock me. Another thing, at that speed sticking your elbow out an inch or two will feel like hitting a brick wall. Resistance to the air in front of you increases as the SQUARE of your velocity. The HP required to get over 200 is about 205 by my calculations and that's provided you can cram yourself tightly enough in there.

 

I too can confirm redline in top on a stock bike.

redline or rev limiter? im sure with correct conditions and right wind, it would do it bone stock. but still its not more the 183-185 actual MPH which is below the government 186 mph standard they have in place. but who cares... reallot not much difference in 180 or 186 mph.. still fast.


now i have been 187 mph on a bike in 1/4 mile on turbo busa.

 

My Gixxer is certainly limited to 186. I've tried it myself. It rips up to 186 and then comes up against a smooth limiter. There was certainly more to come from the bike. My buddy has a K2 with a de-limiter on it and he has had his bike into the high 190's . But thats indicated speed not true speed of course.

:iamwithst

I also have an 03 GSXR and when i see 302-303 km/h (186mph=300km/h) it also have that smooth limiter feeling, just like if somebody had pin a trailer to my bike. It's probably good for another 5 mph because it still pull hard before it happen.

this does make lots of sense to me. Over the past years the bikes 1/4 mile times have dropped and the hp has risen, but the top speed has stayed the same.....always seemed a little fishy.

 

here the speed limiter is a guy on the side of the road with lights on his roof and a police radio.

 

Oh yeah? Well I just did the kessel run in less than 12 parsecs!

So what then manufacturers?!?!?! I didnt feel no rev limiter!!!

hmm, i've never heard of the millenium r1...
