Graves Motorsports Kawasaki ZX-4RR Top Speed Dyno Run

[MK-hbxc]

Just remember it takes about 4X power to make 2X speed on the road against the wind... aerodynamic drag.

Oh my.
Sounds amazing.
Nice downshifting too. 😉

Graves is the man.. PERIOD.. I wish you would get a airport run on the bike top it out and show How badass This bike is I say real world 150MPH From a 400 I AWESOME.

Nice job with the dyno run. I used to build race engines for 2 strokes. Alot goes into building a motor. 🤣 Skills I'll never use again. I know I have just over 10 years of dyno tuning. 3 - 5 tests a day for 5 - 6 days a week, for 10 years. Running that dyno takes practice. Operating the bike, the dyno brake, shift points, starting the run. Single gear or all gear run. My buddy I raced motocross with worked with us for about 2 years. He was faster than me on the track, but could never figure out the braking and operation of the dyno. He would constantly stall the engine by hitting the dyno brake instead of the test button. 😂 I would laugh and he would get so pissed off. My dad was the owner of the shop. He would yell and say, "Get him off that F'n dyno, you do it Paul!" 🤣👍

For people confused all it means is that’s the highest top speed that bike can achieve with stock gearing if you have upgrades and optimal conditions and probability a very lightweight rider 😂 there is nothing to slow the bike down like on the road so you are able to easily achieve the maximum speed your gearbox allows like the bike has 200hp

Thank you very much so much for this video. Very informative.

What are the hp & tq numbers? Why is no one posting dyno results?

[motoevelocidade]

173 MP/H = 278 KM/H But the RPM limit at 17500, its stock? Or have you made any changes to the ECU to release more RPM?

[RT-pbpp]

Now that is what a 400 should sound like, no twin 400 comes close to that power or sound. Sorry guys the twins ain't shit compared to sweet small displacement inline 4

This speed is stock or already flash ECU sir?

[DarkyMoto]

What type of ZG Windscreen is this? Is this the Corsa or Sport Touring?

[JamesHester-zn]

So, theoretically, this bike can reach a top speed of 171 mph. I'm guessing that is with a ECU flash and am exhaust replacement.

[VishalNehra]

God damnn 😳 and I thought 253kmph by Kawi Indonesia was too much

[vaheyepremyan]

this dude's downshifts prove that I still don't know how to ride.

[mchaelc]

How loud was it? Whats the decebel sir?

[entername]

My friend please clarify whether it's km/hr o Miles per hour?

[APtS_GhstHuntR]

wait this is on mph? so around 265kph? how come this doing the same speeds and the zx6r?

[gameadventures]

The fact this 400 makes as much power as mt sv650😭

[JavierV]

Quiero reprogramar la ECU de mi zx4rr, estoy en chicago, como debo hacer ?
