Yes Yankee99 the 2013 has 32 crank-hp and the 2008-2012 has 33 crank-hp.

And you and Mania are right about the weather, but we have to take it like it is. thumbsup.gif

Maybe one more thing like Mania always tells us about the bore and stroke where he is absolute right the 300 now is (excuse me I don't know the english word) a more long-stroker and that means the engine doesn't like high rpms (here the best example is the Jaguar E-Type, make this engine rev high and you'll kill it).

Take the Ninja from 1987 up to 2007 and you'll see this one likes to rev up to 14,000 / 14,500 rpm while the 2008-2012 does this only up to 12,500 rpm.

Maybe this could be one reason for Kwaki to install a lighter alternator in the 300 Ninja to give it the chance to rev a little bit higher then it normally could.

I see the sun's coming out and when you out have a safe ride.

This is an interesting clip I found on a Thai site.

Some things to note that they were talking about.

1- This is in Brazil on the Kawasaki 300

( I cannot help but laugh a bit at how crazy they are to be in shorts & slippers

not unlike many young Thai's )

2- The Thai guys are pointing out that in this clip they think the ABS interferes with

the slipper clutch being a big benefit. ( I don't know & have not really analyzed it )

3- They point out that the 300 can only seem to do 178-179 kph on this long slightly downhill section unaided.

Wind resistance etc. limits it at that point even with mirror folded back & it is out of steam.

4- They note that the 194 kph can be achieved by the fact that he tucks in behind a CB500

& drafts it up to 194 kph

Anyway just something to see.

Good find Mania

at least it takes the 300 rev up to 13,500 rpms to go 195 km/h speed.

I did the calculation only up to 13,000 showing on the thumbnail but 195 km/h is 13,500 rpm in real.

And when you remember that all respectable tuner talk about 12,500 as the highest realistic rpm for the 300, so hm...

tbh, it seems surprisingly slow accelerating from around 130/140 up. If the speedo is optimistic even more so.

Hey Mania, if you don't mind me asking, I believe the great sound from the N250 is also due to the firing sequence, where each piston is fired separately, giving it a much smoother and less thumper like sound? I think the H500's and K650's are the opposite and both pistons fire at the same time, giving them a less smooth more thumper like sound. Is that actually correct? And if so I presume the N300 follows suit and has the same firing sequence as the N250?

I dont know but maybe Gomyway will chime in.

I would tend to think they are the same though because really

the 300 is just a stroked 250 for the most part

having a longer stroke does not neccessarily mean it wont like to rev high.

when i stroked my bike, it performed better in every single rev range, of course there are limits as too how much you can increase it though before it gets too out of balance - keyword is balance ;)

I think it will have similar characteristics to your current n250, just more torque.

They lowered the compression ratio, more than likely increased valve size and ports, and the alternator as pointed out is down 2 amperes, this sounds like they shaved the magnetic flywheel to lighten it up opposed to rewinding the stator, probably increasing the ID diameter by around 1-3 milimeters. The slipper clutch, if its lighter would also lighten up the chain of moving assemblies attached to the crank. Since they didnt increase bore, they didnt increase piston weight either. All these point to an engine that has been engineered to keep revs up.

I keep wondering though if its a different crank or just an offset crankpin. If its a different crank, there could be a chance that the clutch and flywheel might not be a direct swap out if they changed the diameter of the crank shafts on either side of the engine.

But, yeah im just guessing.smile.png

Before I start talking please let me say that all of you are right with what you're saying.

About the firing order from what I know the 650 Kwaki is the same like the 250 and 300 and I'm not sure (didn't look now) but I think the H500 is the same also.

And now please let me show you a picture and I'm sure it makes it easier to understand.

Mania I'm sorry to contradict you since you calculate bore against stroke we do it the opposite way, but at least the result always points in the same way.

To compare apples with apples you have to take the pears away and so I'd bring all bikes to the same cubic capacity from about 1000cc, this makes it easier to look at the value of power.

Panigale 1198 195 162,8 10750 112 60,8 0,54 1,84

The columns show: Bike, cc, hp, hp per 1000 cc, rpm, bore, stroke, stroke to bore ratio. In the last row I show the bore against stroke, the way how Mania's doing.

Interesting is the Suzuki GSX-R600 has the highest power ratio and even when the Panigale doesn't show it in this picture, never forget it's a 2-cylinder and this bike has the same weight like the bike with the lowest power - the Ninja 250. (Also it's a given fact that in reality there is no BMW S1000 below 200 hp when it leaves the factory, the spread from this engine is always in the higher range).

One very important thing about the numbers also is and this makes the Honda looking in a brighter light: It's all about EMISSIONS and once again Emissions and also for sure the MPG...

I wish you to have a good start in the new week and a safe ride.

Gomyway I really enjoyed that post

You did a good job of normalizing things & then look at the engine characteristics

in a sense

Very interesting

Also funny & interesting to see the S/B ratio

For the engine RPM figures are you using the manufacturers claimed rpm or a formula?

I have seen 5252xhp/torque used as a formula but I know your not using that as it would give the 250

a value of about 9500 rpm

Thanks for the interesting post I am going to save it

Like you I know numbers are just numbers but like looking wink.png

Looks like another wet day or two here

wishing to try my new front springs but looks like not today sad.png

Thank you Mania for your agreement, I appreciate it.

Thx for reminding me, the rpm figures are the factory given for power not for torque.

It looks like today is no day for going out with the bike...

They have all 3 colors now in Cm Kawasaki

I wonder why they used red rim stripes on all three this year

The green last year looked better I think

Just noticed the 300 comes with a tank protector already in place

Also a big difference in how they run the exhaust

must be something to do with the added torque.

I know when I ran the devil pipe it added large amounts of mid

Some folks were asking about 2013 used prices now.

This one is less than 3 months old & 3xxx kilometers run
This guy is willing to take a pretty good hit considering the parts he has installed already
total 54k baht. Full 2 brother system etc.

He is selling for 154k

1016863_639540066065273_945257600_n.jpg

If it is too move up to a 300 kinda nuts IMO

The 300 is great for new buyers as it is 20k or so more than the 250

But if a guy with a low mileage 250 sell for such a loss & then add the new price + insure & reg of 300

they are looking at 100k to upgrade 50cc & the slipper clutch/abs?

Not such a great deal in my mind.

Not to mention if he is asking 154k he will probably take less

There is a notice in Thai that some of the 300's are being recalled for ECU

I believe they have listed the affected bikes as being

manufactured in the period 16 July 2012 to 27 April 2013,

Problem causes bike to stall during deceleration

Yes all US bikes are being recalled for the Stalling fault (ECU replacement) and a second fault with the ABS on some bikes.

Will Thailand recall bikes if such problems exist with the bikes here.......... I certainly hope so!

Just to keep things clear; the ABS issue isn't limited to Kawasaki but rather the Nissin unit. Apparently the unit has been used on the Honda CTX700, Suzuki Haybusa, etc.

That new swingarm from RSV looks good

I have to say I like the 2013 color schemes better than this years colors though.

I was planning on getting new tyres for my Ninja this weekend. I contacted Showpow about the Rosso IIs and they are sold out of the front tyre until next month. They have Sport Demons at 5750B for the pair.

Does anyone have Sport Demons? How are they on the Ninja?

Macknife, check big wheel Bangkok.

maybe they have rosso2s in stock. Their service is also good with free balancing, labor and ac waiting area.

Sport Demons should be fine.

I'm not sure now but I was under the impression Sport Demon is just the narrower version of the DRIIs, e.g. for smaller displacement bikes. Didn't even know you can fit DRIIs on a Ninja 300.

Thanks Nik.

DR2s are very popular on the ninjas.
