Really really hoping that these guys got the same canada gearing and that in america/EU we get a shorter gearing.

"For reasons", I'm suggesting these are the realistic mph at 16K: 55 / 78 / 99 / 120 / 139 / 155. Particularly this aligns 130 mph in 5th at 15k peak power.

Still don't understand why the Mustang video is indicating insane 193 kph / 120 mph top of 3rd. Maybe PH got a 15T/43T Frankenstein bike -- their engine stroke (+0.2mm) is already different than the rest of the world to satisfy their local 401cc freeway law. The bike is not even mentioned on Kawasaki PH website.

Confirmed that at least one PH bike (YT: Kenji Moto) doesn't have 14/48. Rider reported 43T rear. I assume 15T front, which makes GC numbers about what we see in the first video. USA has 14/48 for sure.

Looks different too. The overly zoomed one is from the US kawasaki site, other one from a YT video.

A poster after my own heart. I looked for 20 minutes for a clear PH rear sprocket shot from the left side!!! Every video pans up and over the sprocket like clockwork, lol.

So if I got that right this means US gearing is a lot shorter right?

Yes, it seems PH sprockets are overall 19.6% taller. See post #21 for US values.

According to a trusted source for ZX4RR specifications, I performed a calculation based on the gearing ratio of the ZX4RR 2023 model using Gearingcommander.com. Here are the results. I believe there must be a significant difference between the ZX4RR speedometer and GPS (actual speed).

Thanks for doing this @VFR400R NC24 VN. Welcome to the forum!

USA 14/48 ... (PH has different sprockets) edit: Indonesia (14/48) video out today, confirmed.

If PH applied 14/48, i believe speedometer will have huge error compared to GPS =)). Could you please provide PH sprocket gearing data?

 

[kaanivore]

Anything near a top speed of 150 would be pretty amazing imo

 

[Archany]

150 is what I was expecting, since the ones years ago made like 143 or so

 

[xorbe]

Could you please provide PH sprocket gearing data?

I was told 43T rear by PH owner, and I am guessing 15T front. I asked several YTers if they could tell me PH sprockets, but only answers for rear, nobody takes off the cover to look at front.

I'm looking forward of listening to bikes on USA soil with different full exhausts on TSTs dyno !!

This photo was taken from the ZX4RR owners manual. (Philippines)

Looks like PH gets 43/15 and ID (Indonesia?) gets 48/14.
Hope this helps.

 

[xorbe]

Well there it is. I wonder what they think about it.

Thank you for your data. After recalculating, the results looked unreal to me. =))

Man, those number look crazy. I don't even think a zx6r goes that fast

really interesting calculating data, can't wait to see actual dyno data and GPS verified top speed for US vs Asia Version.

 

[xorbe]

actual dyno data

cough post #29 cough

edit: Looks like they make 13T for Ninja 400, and looks like they make up to 54T for Kawasaki in general, so running -1/+1 (13/49) should be fun without having to change the chain.
