hello does anyone know how much horsepower a stock kx100 has?
About 22 to 25 I belive!!!!!
20.1 at the wheel lol
The KX100 makes around 26 rwhp.
well witht he bore and stroke probably making it around a 99.8 cc, there is probably 99.8 horsepower because everybody knows that one cc is one horsepower. I suppose 25ish sounds about right when a 125 makes around 31ish.
Standard calculation of a modern 2t motor is 0.2 hp per cc.
The standard for the 4t is 0.12
20 HP just as a rule of thumb.
You would need a 166 4t to be of equal.
This calculation is paraphrased from a article
by the designer of the "Yamaha" engine.
As chokey said, about 26 or so. I have a friend that had an Eric Gorr built 107 for his son. They dynoed just for the hell of it, 37hp. It was wicked.
holy shit 37hp thats dirty
37... whp or bhp?
37... whp or bhp?
What's the difference?
What's the difference? Thanks,
Where its measured, at the rear wheel or at the output shaft I think he is talking. Bike dyno's normally measure it at the wheel, there maybe a machine to measure it at the output?
chokey, i couldn't find any percentages for bikes so i guessed. and suposedly automatic AWD cars have a around 25% i don't believe that though
but damm, 37 out of a 100(107) is crazy thats like riding a 170lb 144 with tiny wheels, i couldn't keep the front end down on a regular 100......
i couldn't keep the front end down......
Why is that the statement everyone uses to describe the awesome power on a mini....any adult on a mini will find that the front wheel is hard to keep down -
an indication of power....not so much....
an indication that your A$$ and center of gravity is way to far back because the ergonomics are not designed for someone of your size....more so....

An auto AWD car will lose much more than 25%. Typical rear drive automatics lose 20-25% of hp going to rear wheels. Stick shift about 15%. The only way to improve on an auto is to have a purpose built tranny that has custom valve body, better clutch packs, etc. But even on a dyno, you seem to lose more hp because you run a stall converter. But your e.t.'s drop drastically.
As for the 100 I was referring to, I was just reminded that it did have a phathead flat top piston & head set up running 118 octane mixed at 50:1.
So yea, it ripped.
A 65 makes 18.5 at the crank, so a 100 probably makew 21 22, but I hear its extremely tame and you will need a pipe to wake it up.
My Manufacturer's Statement of Origin from Kawasaki reads 29.2 horsepower. I'm not saying that it's correct but to put it into perspective, a KX125 with only 25 more CC's is in the low to mid 30's. It's also 50 lbs heavier
its not HP, its the rider, pointless to figure it out.
