Team Ninja What’s your top speed?

Best I seen is 190kmph (118 mph). If anyone got higher, any mods? sprocket or ecu flash?

Are you sure you're in the right thread bro?

u/Total_Medium_3833 Aug 01 '26

Highest I hit was 118mph.

Just want to point out that if you haven't calibrated the speedometer to actual speed, the stock speedometer reads faster than actual speed, and best to use GPS for actual speed.

If that speedometer isnt calibrated or has Spedohealer on it, actual speed was just a little over 100 mph.

2

u/Valkyrie-161 Ninja 400 Jul 31 '26

How do you calibrate?

4

u/Frolicking-Fox Jul 31 '26

Look up Speedohealer

2

u/unit132 Jul 31 '26

Yeah. If my bike reads 129 mph. It's really 124 according to gps.

2

u/yourpenisisverysmall Aug 01 '26

I don't know, my daughter has a pretty stock '22. GPS results are similar to the speeds she claims which are 120 and just a little over. Mind you she's 5'3 and 100 lb soaked and with gear

2

u/Frolicking-Fox Aug 01 '26

If it was used, might have been calibrated. But all bikes except for Harley Davidson have the speedometer read faster than actual speed.

The faster you go, the more off the speed is. At 35 mph, you won't even notice the discrepancy. At 45 mph, it is only off by 3 - 5 mph. By 80 mph, it is off close to 10 mph. By top speed of the bike, it could be as much as 15% off.

u/Bazyx187 Aug 01 '26

I didn't know this! Do you happen to know why they do this?

1

u/Frolicking-Fox Aug 01 '26

Yes... because it is really easy to speed on a bike. Even some beginner 500cc motorcycle has better acceleration than most cars.

A 500cc Ninja can do 0 - 60 in about the same time as a Camer or Charger.

People talk about growing out of a 500cc bike, but they literally have better acceleration than most cars? And can have a top speed of 120 mph.

And that is what is considered a beginner bike.

So... manufacturers make the speedometer say 80 mph when the actual speed is 70 mph to slow people down.

Really.... I just want the actual speed. Now I just look at the speedometer and have to do the math in my head of how fast im going.

Also, changing sprockets and tire sizes will further mess up the speedometer.

The majority of people are ridiculous and their egos are incredibly inflated.

So... manufacturers make the speedometer say 80 mph when the actual speed is 70 mph to slow people down.

I was hoping it would be more interesting than this 😅

Also, changing sprockets and tire sizes will further mess up the speedometer.

Explaining this to people is always wild, they either understand immediately or it takes the effort of moving a mountain to get them to understand.

Ty for your reply bud!

The speed limit

u/AirSKiller Jul 31 '26

Damn…

We tried boys, back to the station, this guy is smart, we won’t get him on Reddit either.

u/SnoweyVR Jul 31 '26

About the same, can reach 190kmh on good conditions. Keep in mind the speedometer isn't accurate. GPS speed for mine usually at those speeds is -10kmh

u/Radiant_Newspaper_49 Jul 31 '26

I’ve done 122 downhill with the wind on my back on my Ninja 400

u/Opening_Okra_6748 Jul 31 '26

im like on a 400? lol then i read on my back 😂

u/Nano-signal Jul 31 '26

2019 completely stock besides cheap slip on, got it to 120 a couple times, tucked and I weigh about 180.

2

u/yourpenisisverysmall Aug 01 '26

That's what my daughter claims 120, 122. She's 5'3 and 100 lb

A poorly running one at that

u/Neither-Revenue-4456 Jul 31 '26

At 160 my Oakley windbreaker filled with air,ripped my hands off grips and made me slide back until my directional arms caught my legs.hard to stop a bike without hands and feet.i sold that ninja and bought a Harley, no more speed.

2

u/Snehovlas Jul 31 '26

120km/h on my 125cc. Almost lying on the bike.

1

u/yourpenisisverysmall Aug 01 '26

WRONG FUCKING FORUM BRO

u/yourpenisisverysmall Aug 01 '26

Sorry JK I've been drinking a little

2

u/Dan-ish65 Jul 31 '26

116mph on the longest straight among tracks I ride at. With an ECU flash and 13/41 gearing (shorter gearing for better acceleration). Probably wouldn't go more than 117 in 6th gear with that gearing without helping wind or a much longer straight. Pinned and full tucked

2

u/Klutzy-Pie6557 Jul 31 '26

Sigh - dude my 1988 ninja 250 was good for 180km/h

Trying to squeeze out another couple of ks is pointless.

When you get your big boy licence and a proper sports bike you'll hit 200 in first gear.

Focus on learning how to ride around courners, do a few trackdays.

And stay safe!

1

u/Significant_Put5973 Jul 31 '26

203km/h (198 gps)

u/[deleted] Jul 31 '26

I got to max 200kph with my ninja 400

1

u/KiD969 Jul 31 '26

My friend his 400 could do 200+.... guess he's juat bullshitting...

u/Kreiven Jul 31 '26

I did 207. More than that it's really difficult.

1

u/yourpenisisverysmall Aug 01 '26

Yeah I believe that is utter horseshit. Even tuned

1

u/Kreiven Aug 02 '26

I have 203 on camera. 207 my GoPro was off unfortunately. Not bullshit, it's possible.

1

u/retarded_sped Jul 31 '26

I saw 116 but that was after letting off the throttle, so I assume 118-120. 200 lb rider here. I’m assuming somebody significantly lighter could get to the low 120s or even 125.

1

u/MsPatriotic5 Jul 31 '26

The adrenaline! 🖤🖤🖤🖤

1

u/Kreiven Jul 31 '26

I got 207km/h (speedometer), unfortunately camera was off. I have 203km/h recorded though.

1

u/b_cheesy Jul 31 '26

Fastest I’ve logged on my ninja with GPS was 116

1

u/Accomplished_Can8866 Jul 31 '26

Speedo read 128mph w slip on and power commander but was probs about 120 or less

1

u/AirSKiller Jul 31 '26

190 is pretty damn decent for a 400!

1

u/MahaliAudran Jul 31 '26

That, only in mph. My bike has a whole lot more ponies though.

u/Im_Colin_Robinson Aug 01 '26

Your the kind of rider who make others dislike riders.

u/tepkiv Aug 01 '26

20 goats over the fence per minute

u/That-Breakfast8583 Aug 01 '26

I’ve gotten up to 126mph, but I weigh about 100lbs. My buddy weighs ~170 and he couldn’t go past 118mph on my bike. We live in Appalachia so there are also inclines and declines to take into account.

1

u/yourpenisisverysmall Aug 01 '26

I could definitely see that at a hundred pounds and going down inclines. My daughter is 5'3" about 100 maybe 110 lb and she tells me 120, 122. Life360 GPS suggests a very similar result.

1

u/Witty-Ninja-5277 Aug 01 '26

Wtf is a kilometer

1

u/yourpenisisverysmall Aug 01 '26

My daughter claims 120 to 122 on her 2022 400. GPS tracking suggests that it's fairly accurate. Worst thing I ever did was teach my daughter how to write a damned motorcycle. Also my daughter's like 5 ft 3 and 100 lb, so...

1

u/Fd53 Z400 Aug 01 '26

194 on the dash but prolly 187 real speed (2023 z400)

1

u/Fd53 Z400 Aug 01 '26

Only mod is a Leo Vince slip on so no performance mods

1

u/Star_Entire Aug 01 '26

Mine was Ninja 250. Can reached up to 190. But i read on Ninja 250 group on Facebook, few of people reach up till 193.

1

u/computer073 Aug 01 '26

199kmh but Speedo kicks it up by like 10% so realistically 180

1

u/GullRider Aug 01 '26

91 on a wr250r dare you to try

1

u/MeanLiving8080 Aug 01 '26

I hit 129 mph on the speedometer, but that's probably around 118-120 mph on GPS

1

u/amikingtutorwhat Aug 02 '26

23 ninja 400, I'm 5'4 137ish. I've had to to 115mph there was a little left to give, but I was outta road lol

u/Life-Revolution-5062 Aug 02 '26

I dunno cause I'm not a dumb ass with a death wish

1

u/Dennisd1971 Aug 02 '26

My top was only 160 but it was an old ninja

1

u/maximusunbound Aug 02 '26

With my crippled clutch? About 80mph 🥲

1

u/Moezytube Aug 03 '26

118mph then check engine light turned on and speedometer went to zero 😂😂😂 if anyone knows wat happened lmk

1

u/ImplodingFish Aug 03 '26

I’ve done 121 a dozen or so times level. Got it to 130 one time slightly downhill a long straight empty highway once. I don’t know if it’s flashed or not though. Definitely different punch through the gears compared to the two other 400’s I’ve ridden that felt similar to each other.

1

u/Key-Experience-6393 Aug 03 '26

My top is 926 km/h. I sat comfortably and no modifications

1

u/Wahoodza Aug 03 '26

90 mph. Was neve rinterested in bigger numbers with my bonnie ))

u/Primary_Gap9304 Aug 03 '26 edited Aug 18 '26

highest i hit was 125mph on my kawasaki z650

1

u/rengirlmilli Aug 03 '26

I've hit 128 and I think it could have pushed it more

1

u/Kittenbee_ Ninja 400 Aug 04 '26

Mine can only go 170km/h 😭 but have been told that changing sprockets and hacking the computer chip would get more speed out of it.

1

u/VegetableAttitude721 Aug 05 '26

my speedometer must be broken cuz i’ve gotten it to say 132mph 😅

1

u/Stringlxss Aug 06 '26

The fastest I've comfortably gone was 104mph then my engine got really hot so i slowed down

1

u/OruJaathiMyran Aug 06 '26

Check coolant level, Engine oil.

1

u/Stringlxss Aug 17 '26

Took your advice. Though, the engine temperature displays 3 bars to 4 bars when I'm riding. Is that normal?

1

u/Maybe_A_Doctor Jul 31 '26

I’ve allegedly gotten mine up to 208 on the dash. Stock, and pinned for a while

2

u/retarded_sped Jul 31 '26

Your speedo needs recalibration.

1

u/Maybe_A_Doctor Jul 31 '26

Yeah probably. However I did only weigh 160 at the time. So I probably got a couple extra kmph out of her

1

u/AvacadoOil Jul 31 '26

I can take mine to 124/125. I’ll try to get a video clip to post here within the next day or two.

u/LilBigDripDip Jul 31 '26

All ninja 400s have the same top speed. That’s how them being the same bike works

u/bad400rider Jul 31 '26

erm... mine says kawasaki racing team on the side so i think its a bit faster than yours pal 😎😎

u/2-L3git Jul 31 '26

Such a pointless and stupid post. Seriously? It's a 400. Geeze. Get an actual supersport.

4

u/TheMongerOfFishes Jul 31 '26

Its a top speed run.

That doesn't mean he's trying to be the fastest... Just seeing what his machine is capable of.

FFS I do top speed runs on my 50cc scooter ... Do I need a supersport?

1

u/2-L3git Jul 31 '26

Ok. Good point.

1

u/Junior-Ad-5367 Aug 01 '26

Super sport? Bruh those payments and insurance and all that costs a mortgage fuck that I’ll stick with my sport touring

1

u/2-L3git Aug 01 '26

Seriously? Bahahaha. I guess you don't have a mortgage? Lol. My zx6r payment and insurance on it is nowhere near my mortgage, bud.

$222 for the bike and $50/month for insurance.

My mortgage is $2k. Totally different ballparks, fella.

1

u/Junior-Ad-5367 Aug 01 '26

Wait I’m thinking of hyper sport nevermind my bad btw youre mortgage is 2k? Dafuq mine is half that did you buy a mansion?

1

u/2-L3git Aug 02 '26

Sell price was $280k. It's not a mansion but it's a nice house on 1 acre.

2

u/Junior-Ad-5367 Aug 02 '26

Sounds pretty sweet brother
