About top speed?

[Vad18]

So.. I can not hit past 86 ish...
I checked, I am in 6th gear, at 86 I red line.
I weigh 135 pounds so its not my weight, I tuck in too..

Its not like I need to go past 80 anyways, but I heard that the ninja can do 100 without a problem almost, I am struggling to 80?

[alex.s]

by red line you mean you actually hit the rev limiter? or it just stops going faster?

are you tucked?

Tucked yes,
It touches the red line, so it wont go all the way. After I posted, I saw some similar posts pop up, someone said do 80 on 5th, then switch.

What are your RMPS at in 6th @ 60pmh? Mines around 8.5-9k

the inaccurate tach touches the red line? or the bike actually hits the rev limiter. if you don't know the difference look it up.

Just touches the red line. I mean It probably could hit 90. its a slight uphill, don't really have too many places to test it out.

[cbinker]

run 5th till the rev limiter.

[alex.s]

so you are just stopping because of what the tach says? not because the bike stopped accelerating?

Alright ill probably try, and tell you how it goes.
@alex.s Well I thought I was killing the bike , but I had the throttle all the way, might be that I need a straight road to try it on, and maybe redline 5th then go 6th.

I just thought that it should hit the 100 before the rev limiter, but I guess it can still accelerate more.

[alex.s]

i will say... its probably not smart to go that fast on a public road... you will get put in jail if you get caught going that fast. not to mention its stupid and dangerous.

but... it will probably do it fine. and its fine for it to run at high RPMs. what hurts the motor is spiking the revs past the limiter using engine braking.

the limiter makes the bike sound like "BWahhp BWahhp BWahhp BWahhp BWahhp BWahhp" instead of just "vroooooooom"

it's not great to bounce off the limiter though.

[jeffb502]

Here's my Ninja 250 indicating 80mph at 9000 RPM in 6th gear. Still plenty of room to redline and if I wanted to go faster than indicated 80mph it would have done it no problem.

Link to original page on YouTube.

I never did try to reach the top speed on my 250. On my 300 the fastest the speedometer has read has been 110, near the top of 6th gear.

Well it is a public road, but its like a backroad, but yeah I know, probably will stay with the limit. I just thought there was something wrong with the bike.

see this is what im talking about, why am I at 9000k at 60? Is it just the sproket change?

Did you change the sprockets on yours to make it accelerate quicker? If so then yes, you lose top speed when you change sprockets to improve acceleration.

[Vad18]

I didn't but maybe the guy before me did. I will need to run again to see what its at, but yeah. Is your's fully stock?

[jeffb502]

I just assumed my 250 was stock; I didn't know how to check.

[Vad18]

So which one is the one that I would need to check for the teeth amount, the front sprocket or rear?

[Klondike1020]

Count the teeth on your sprockets and see what they are, thats probably the reason.
step two
IF you need to go faster than 80 you must live in germany and be driving on the autobahn.

in that case sell your ninja and buy a liter bike
finally
if you really need to make it go faster
Drop it off a cliff. it should reach 100 before it hits the ground.

make sure duck tape your phone to it so that the accelerometer can tell you how fast it was going before it stopped

also use a otter box. if the phone doesn't survive you will never know how fast it went

Well highways in the United States now average 75-85 speed limit so I guess we all need to get a liter bike. Its also called traveling at the speed of traffic just because the speed limit is 65 drivers are still doing 75-90 in phx and if your going the speed limit your going to have a bad time.

Oh don't worry. The 250 is plenty fast for me. I went from a 50 to a 250 . Its not that i need to go faster. But my rpms are so freaken high. I thought it was normal to be at 9k at 60. But after i tried going top speed and hit 86 at the rev limiter. I asked the top speed question here. I will need to open it up better to count the teeth but it looks like the front has 13 or even 12.. And stock is at 14. So looks like it was swaped. I just dont want to be on the freeway going at 9-10.5k rmpz. Plus i need to go faster during situations and i cant

by your own statement you say speeding at a minimum of +25 on back roads is not fast enough. but you then contradict yourself because you realize how stupid that sounds.

how long have you been riding? sounds like not very long. i think you should reevaluate your skills and come to a better conclusion about what is safe and was is flat out stupid. i don't like being an asshole to people but i will absolutely be one if someone is acting like an idiot. and based on what you are saying you are absolutely acting like a child with a toy that can kill in an instant.

not to be a wet towel. nobody likes a negative nancy. but be smarter. a public street is not a drag strip. you clearly are not comfortable mechanically with the bike as you don't even know what the final drive is after going out and counting the teeth. how can you say that the bike is even safe to ride at 65, let alone 100?

you are acting like a squid. sorry to be blunt. learn more. be more humble. and slow the **** down dude.

[broilmebk]

Don't let it get you down though. Educate yourself, that's what this forum is here for.

Side note: I keep seeing the '# out of # members found this post helpful'. Is that option only for certain members?

[EsrTek]

Go outside .. take off front sprocket cover and count the teeth (write it down)
do same for rear sprocket..

Take that info and goto this site:
http://www.gearingcommander.com/

Load the stock for your bike (should be Kawi>ninja>250 08-12)
It will load stock gearing, which shows you speeds@rpms below
Compare that to what is on your bike...
I bet you see why your doing 80@xxx rpms

It is possible that your clutch is slipping due to poor adjustment, bad cable, wear or bad oil.

If the clutch is OK, then either the speedometer or the tachometer are giving you a false reading.

It is very dangerous, for you and for others sharing the road with you.
A bike out of control at 80 mph is not a pretty experience.

@ Fishdip - I totally agree, Thats why I got a 750. I am so squid its for real

Now that everyone is done tongue lashing you(or keyboard whipping you ) or whatever people are calling it these days.

Assuming you are a responsible safe rider operator because I have no reason to believe otherwise…. I recommend you use GPS or Mobile phone GPS to measure your actual speed

if sprockets are swapped out then it is likely the speedo is inaccurate

OR at least do it barney style and count the darn Teeth.

get it all sorted out.

I know you are not out to go super fast and risk lives if you are ridding a two fiddy other wise you would be ridding a GSXR with a wheelie bar and mohawk helmet thingy.

Also traveling 60 at 9K can mean a very buzzy commute.

I would get it sorted out so you can really enjoy the bike.

Good luck and NEVER SQUID AND TELL

hahaha

Really man? Did I ever state that I regularly ride @ 80+ mph? Btw, the back road, is the i-90, call it a back road since theres like no traffic there and its all country. Speed limit there is 75 mph. People go Way higher than that. Why was I going 80+? Well because I can. The reason I posted here was because I could not go any faster, I'm not a squid. I always wear my gear, am endorsed, I ride the speed limit, the only reason I went over this time was because I was at 80 and at 12k RMP and wanted to see how much higher it would go, and it only went to 86.! People go fking 90 on there. This is why I made this post, because I was sure that this bike could go up to 100, so I thought something was wrong okay? Doesnt mean I want to go up to 100, but I was sure it was not suppose to be at 12k at 80. Well in this thread I found out that it must be the sprocket.

(Quote) you don't even know what the final drive is after going out and counting the teeth.

Right, dude I went into my garage, took out my phone, turned on the flash light, lit up the bracket where the front sprocket is, and counted the teeth I saw, I saw 6, so I just estimated that there were 12-13, I can count okay? If I took my time, which I will, I just came home, I will lift the bike and check the teeth properly. I have been riding for over 6 years and not only in America, but in 3 other countries.

When I said 50 to 250, its called a joke okay? The guy before was joking with me to go to a liter bike, so I joked back. I have been on bigger bikes before, but the only reason I bought this 250 was because of the insurance and just the amount of fun it is to ride, comfort etc.

Thanks for the information, the public roads speed limit is 75.

The sprockets do not change the speedo, the speedo reads the front wheel. Now the rpms at given speed will be different than stock if changed.

[csmith12]

Yo! Relax, alex means no harm but does speak bluntly, I know, I meet him face to face.

Now as far as 6yrs go, some say this; I have ridding for 10yrs and I have had one year of experience 10 times. So take that into consideration when you read the replies here.

Know for sure your sprocket setup and let's take it from there because my bike on stock sprockets and me being 195lbs hits about 103 or so. Let's get you figgered out.

You should have to count the teeth on the front sprocket, the rear should have a number stamped right into the metal. Check both sides in case it was put on backward.

You are welcome

Insisting on rolling fast in a sustained manner with a slipping clutch can hurt your engine (mainly bearings) because the abnormal increased temperature of the oil.
The faster you try to go, the more the clutch slips and the hotter the oil becomes while the engine is creating more torque and friction among parts.
There is no much surface in these engines too cool the oil down.

Sorry, I didn't know that you were an experienced and careful rider.
Please, disregard my previous comment about loosing control while speeding.

[Vad18]

So I counted 14 teeth..
Alright so I will check the clutch, looks a little loose.

Rears 45,

I have tightended the clutch cable, Seems better now, will go for a quick ride down the highway

[csmith12]

Sweet! Stock gearing, you should have no problem hitting triple digits @ 135lbs in a full tuck.

you are so right

I forgot. I sold my ninja and lost the speedo Cable

I shoulda remembered how that worked.

I was thinking context of my bike.

different sprockets = wrong SPEEDo

+1 for you , 0 me

If the clutch is slipping, the cause of that might be a cable that is too tight. I believe you should have loosened it. I think there should be 1-2 mm of free play in the clutch lever.

[Vad18]

Yeah so I tightended it way too much, the engagement point was so far, so I loosened it up. So RPMS are the same, so am I not counting the damn teeth correctly or its something else, I recounted and even had a friend count them got 14.

These are my current RPMs, I counted while I was changing gears and was engaged in 6th.

40mph: 6,000rmp
50mph: 7,500rmp
60mph: 9,000rmp
70mph: 10,000 and almost 10,5 rpm.

[DaBlue1]

Since you haven't had the bike very long, you've probably haven't gone over it with a fine tooth comb.

Other than the obvious problems you can actually see (i.e. disconnected brake caliper), have you noticed any thing odd with the tach bouncing or reading differently under similar riding conditions. Have you noticed the lights slightly flickering while idling? If so, you need to tighten your battery terminals. Some tend to loosen over time. Despite the fact they may appear snug, they may still be able to be tightened and correct the stated issues. You may also want to check your connections on the back of the tach as well.

If all else checks out, it is possible you have a faulty tach or IC Ignitor. You may need to test the rpms externally to see how accurate the tach is.
You can use an inductive pickup clip accessory on a digital multimeter. The clip attaches to the spark plug wire. If the multimeter is good, it can be set up to convert electrical pulses into a rpm format. With this I believe you will be able to tell if there is a different reading between the tach and actual spark output.
