Stock ECU Vs Tuned! Ninja ZX-4RR Acceleration Comparison! 

We had inline-4 250's, 400's in New Zealand in the 80's and 90's. You can still buy the older ones. I've had the CBR250R (red-linded at 19,000 rpm) Yamaha FZR250R, and the Suzuki Katana 250. The GSX-R 250 had the best power to weight at 138kg and 45hp. I remember going to high school with my mates on our 250-4s sounded like a F-1 race.

Awesome video, I cant wait until i get my first bike

I was regretting trading my 2022 z900 RS 50th anniversary. Then asked about the 400 rr . Dealer said sorry sold out. Get on line. So knowing that the 40th ninja was ust coming out the Salesman said no they don't make one. Then the Other salesman ( a kawi nut like me) said" Yes they do. We have only one coming . So I lucked out. Its got my name on it. The 900 was too brutal . So now seeing this video makes me NOT sorry. The 400 won't loop out in 4th gear but still has 4 cyl sound and giggle factor. I'm pumped. Great video.

Thank you for the follow up!!!

I’m about to get my Two Wheel dyno works tune done, I can’t wait.

I had my zx4rr dyno tuned by Chris Moore at Moore mafia graves slip on and race air filter made 71hp and now my top speed is 153mph 😎

Nice!!! I Enjoyed the video

Ride safe man! Hope to own one soon! Great vid!!

Nice. Looking to get it tuned from them soon

Awesome !!!!!!!!!!

was worried at first but glad it all worked out! what company did you go through again? can they flash back to stock if you have to get warranty work or do you think kawi could even tell? thanks again and awesome video

Can't wait to flash mine. Have you looked into aftermarket exhausts? I'm considering a Coffman shorty exhaust for it

Love your bike I am JELLY.. have ever topped out 6th gear ?? what is the speed i think it can do 150mph

What tune did you go with?

Hey im not onw to sell once i get bored you think this would be a good first bike?

hi bro,i just want to ask i am thinking of getting this zx4r,i know the r7 has alot more torque,is it possible to tune this zx4r too have as much torque as the r7?i am new to the bike world, thks

What all mods do you have on your ZX?

I have one untuned. It's the most fun bike! I don't regret anything

How goes from 100-200 kph please ?

🔥🔥🔥🔥🔥🔥🔥

Brilliant, Kawasaki engineers are complete nutters! I am ordering one.

What octane do you use now? And did you have to disable the O2 sensor, exhaust valve and pair valve?

Specs on the official kawi website here in in the philippines is 79hp bone stock.

Holy cowww😮😮😮

How did you clear the flashing dash and check engine light after the tune?

How long did it take you to receive your ecu back from the tuner?

50hp and after a tune up a whooping 71 HP . Wow , in Malaysia we'll get ours in 2024 . A rebadged under Modenas zx4r SE or RR both comes standard with 77 HP out of the box. 👍

doesnt the zx4rr has 77hp stock ? or am i wrong

So no rear power gain other than you picked up about 5mph? For all that cost is it really worth it. So you get what 50 hp instead 44?

In UK this model got 77HP stock.

thats how it came from the factory here in asia. 80hp

Bro I can make 125mph on 4th gear without reaching the limit full stock

Damn it sucks that I’d have to get a r6 or better to beat my fucking Gti 😂😭😭 my Gti fuckin scoots

8.5 from 30 to 96

05:41 - 52hp to 71hp

can you keep the quick shifter on all the time? or will it wear out the engine/transmission over time.

bike needs 80-90 hp, no I dont want zx6rr hp. I am about to sell mine

In Italia ha 80 cv 🎉🎉🎉 però è troppo costoso meglio zx6R 😂

But at similar price point of 6R its way too costly to justify its price.
