Ah, thanks. I’ve seen that version, but didn’t connect the dots in my fit of snarkiness. :)

the carbon version upsets me, it looks like some of it is just stick on panels and a waste, like on the rear brake reservoir and dash for example. Don't get me wrong I love cf, but some of it is just too far.

So after Lamgvnchy posted here Zx25r Stats and N400

I tried to find the source and came across an Indonesian website.
Apparently the zx25r has been dyno'd by Akrapovic and in stock form is putting down 41.43 HP at 15,350 Rpm and 20.8Nm at 12,700 Rpm
Presumably at the rear wheel.

Yeah I just saw that thread too. That's not very impressive power figures. My LAMS N400 with a slip on and a ECU tickle up is doing a touch under 45 at rear wheel, so I'm glad I didnt throw a deposit down on one of those at $16K a pop lol

It may not be a high-spinning “real” Sportbike and it has two fewer cylinders, but the N400 does have 60% more displacement.

Ha ha! yeah fair call. I guess some of us got sucked into the hype back at the start. Remember the 60HP claims etc. I was thinking realistically maybe high forties as the original ZXR250 was rated at 45HP back in the day. So throw in a few technological advances over the last 30 years and some slippery $hit added to various rubbing surfaces and such like and you would hope for a bit of an increase... maybe. Probably out weighed though by the need to meet all the emission and noise reg BS. :(

Yeah I expected between 50-60 hp. I hope It sells, as I like small bikes that rev, but I‘m not currently feeling like I’m missing anything by having bought the N400. I think the N/Z400 is a lot of bike for the money and I am really enjoying mine when the rubber side stays on the bottom. So much fun to ride such a light & flickable bike.

Man, only 41 whp / 15 ft-lb. But that's still approx +64% power and +15% torque over my first Ninja 250, and I had a lot of fun on that bike.

I've flip-flopped. If it ever materializes in the USA, I'd buy it, 41 whp is perfectly fine.

The video shows 5th gear 160 kph @ 17K though we know small bikes tend to have optimistic speedometers, perhaps this one is more accurate given it is upscale.

I did audio analysis:

1st-2nd 1.3659
2nd-3rd 1.2720
3rd-4th 1.2706
4th-5th 1.2086
5th-6th 1.1597

1st: 37.25 mph (*might be more like 41 ...)
2nd: 50.88 (*might be more like 55 ...)
3rd: 64.72 (*69.6 per new Kawasaki video)
4th: 82.24 (*84.5 per new Kawasaki video)
5th: 99.40 (per track video 160 kph)
6th: 115.28

The data was calculated from 5th gear. That means 4th and 6th are the best estimates, and the error bars grow from 3rd to 1st, with 1st being the least accurate estimation.

Compared to the Ninja 400, this is basically 0.8, 1.2, 2, 3, 4, 5. Oh yeah, this bike will be revving a lot that's for sure! 11.8K at 80 mph.

Speak up!
LOL OK, I will speak up and say that I am sometimes not so good at reading dyno plots. I called BS (5252 rpm rule) on the graphs referenced here before I put my glasses on (or pulled my head out of a dark place, you decide) and realized there were different scales on the left & right for hp and torque.

Sorry to make you confess ha ha, but if you know about the 5252 rule on dyno charts then your probably ahead of most folk. It would be handy to have the option to delete a thread huh.

For those not sure what we talking about:
