How much power do other motorbikes have compared to my ninja 250?
I was watching some stunt videos on youtube, and I kept thinking to myself holy ****!!!
My ninja 250 can't wheelie purely on power, I need to pop the clutch for any wheelieness. It also cannot pull a "stoppie", the front wheel will skid... but that's not power related.
If I full throttle the 250, it's not really a big deal. Maybe in 1st gear it takes some skill, but in just about any other gear it's not particularly crazy.

So how much power do other bikes have compared to a 250?

I just can't imagine a bike having so much power that it'll wheelie 3rd, 4th, or even 5th gear....
Insane.

The 250 is definitely not a big horsepower bike, which is why its able to achieve such good fuel economy. These, the 500 and 650R aren't even in the same class as the supersport bikes that most of the stunters use. It takes a lot more effort to pull up the front wheel on these bikes than an SS, particularly the ZX-10 and ZX-14. Those are the kinds of bikes that will take off so fast you'll feel like your eyes are being sucked into the back of your skull, and your arms are being ripped out of their sockets.

I personally think that the 600 class is the best class to have for the every day rider... not too big... not to small... enough power to make you smile, but yet still good on gas and looks.

The short answer is that stunters use bikes in the 100-130 hp range. These vary from inline 4 supersports to 800/1000 cc twins (Buells, BMWs, the like).

What you must keep in mind is that all stunters change the gearing on their bikes in order to get more grunt down low at the expense of top-end speed (which they obviously don't need) - so whereas my 636 does not come up under power unless at the top of the rev range in 1st gear... the 636 of a stunter will easily come up in 2nd under power alone... maybe even 3rd. However all stunters pull the bike up with the aid of the clutch, as that's what you need to do to get the front wheel up in confined spaces.

a 250 has around 25hp. the new zx6r has around 100. Just imagine 4 times the power and thats what you got. I remember the first time i rode a 600 after being on the 250. I got off the 600 and my knees were shaking. I couldn't believe the power and that was a slow yzf600 with only about 80hp.

Try 125 hp which means 5 times the power :biggrin:

My 06 636 has 130 :biggrin::biggrin:

unless you've done something to it it doesn't have 130hp. I have an 06 as well and they say it has 133 or whatever from the factory but it doesn't. I bet if you dynoed it it would have about 115 with slip on jumper mod and a power commander. Same with the 07's which are slower then the 06's. They have around 95hp even though kawi may claim something higher.

Any time the manufacturers claim horsepower and torque figures, they are reporting average horsepower and torque measurements taken at the crank.

So whereas I can agree with you that at the wheel a 636 only puts out about 115 hp (and I think it could do it stock quite easily, no need for mods), I do not doubt that the figures for horsepower and torque at the crank are pretty much on the money. The important thing is to compare apples with apples - if you are talking power at the crank it is one thing, at the wheel it is another.

Since the number that almost everyone knows about their own bike is taken at the crank, usually that's what people refer to when they talk about horsepower and torque figures.

Lots of the serious stunters also put huge sprockets on the back too, don't they? That allows them to pull the front end up right away without even using much of the power. Put one of them on your 250 and I'm sure you could get it off the ground, but not very ridable on the street. I believe there's a guy from europe who posted on the 650 board that he uses a 650 over there to stunt with.

With the right gearing you could stunt with pretty much anything!


Adn yeah most of the horsepower numbers from the factory are at the crank....not the wheel. You gotta take into account parasitic losses. :)

my 650 (07 ninja) is rated 70hp, and its fast enough for me, on 2 wheels at least. :)

I ride an 07' ninja 250 and although I realize the power is minimal compared to even a 600cc bike let alone 1000+cc bikes, but the power it offers is plenty for a pretty new rider. I got my bike nearly 6 months ago and I think it is great. I have so much fun on it and it offers enough power for that but not so much that I can't handle it. I do hope to own a zx6r in a few years when I finish up with college and get out in the real world, but I don't want to jump into something bigger before I have mastered my skills on the 250.

Oh and I can pop a wheelie by clutching it, only have done it in an empty parking lot and that is enough for me, I would rather not kill myself trying to show off in traffic.
