Exact specs are apparently more than a quick google search away.
Think about it though, 10mmx10mm x 6 cylinders won't get you to 249cc.
I so want one of those bikes.
You're right, my numbers were wrong.
I must have been thinking of the 125 RC 149 5 cylinder. Even then my numbers are still off. I can't think of what it was I was remembering.

I do remember reading about something Honda tested but never raced.
I thought it was a 125cc 6 or 50cc 6 or something like that. Rev'ed to 25K with like 8 or 9 speed gear box.

It was too long ago. Maybe not a Honda?

Anyway, my bad. Sorry.

These are examples of the last performance based products Honda cared to build.

I feel like people on this forum don't know how to read...

All I can say is if RPM equals power then why does that honda only make 16 hp if it will rev all the way to 20k?

You mean 60 hp with only 17 lb/ft torque?

No one said RPM equals power. It is part of the equation in determining power.

The Honda NR500, although unsuceesful, it ran at 19,500 rpm in race tune for 81.

http://www.motorcyclespecs.co.za/mod...racer_1979.htm

But the '66 RC116 was 21,500 rpm putting out 16hp with 50cc's. Pretty incredible.

This is the post I was referencing about 16hp

And this is what I was referencing about rpm equalling horsepower. Back to you ogre.

P.S.
RPM is part of the equation that most people use for power because it's a simple equation and RPM happens to equate to time, although the actual equation uses time depending on what type of horsepower you are calculating.

Hp is a time related measurement of how much work can or is being done in a minute, so rpm IS horsepower.

I can read just fine. I just figured you had no fucking idea what you were asking, so I corrected you before looking uninformed.

This would only be true if every combustion engine produced the same amount of torque because in our case "torque" is the "work" that is being done.

Uhhhh, no. Torque, like force, is not work.

Torque x angular displecement = work, work / time = power
Force x distance = work, work / time = power

In HP equation, the use of R.P.M. has both the angular displacement and time components covered

Thank you to the intelligent people on this forum. I finally have something more intelligent to read and the ability to learn it

...and the feeling is that there are no stupid questions just people that pose them.

Because an engine is an air pump, the more air you can get in and out of the pump the more power it makes. A small air pump can only suck in and blow out so much air, so if you increase the RPM and everything else being able to sustain more airflow in and out of the pump, you can pump more air, making more power. Hence why big slow spinning engines can make so much power, because they can suck in and expel more air at every given engine cycle.

torque is measured in lb/ft (in America). one lb/ft is a 12 inch lever, set horizontally with a 1 lb weight on it. 2 lbs on a 6 inch lever would also be 1 lb/ft. when you rotate this lever at a certain amount of rpm, that determines how much hp. it you can spin it twice as fast, you double your hp. that is why i said hp is simply a time factor, because basically, it is.

torque is how hard is pushes, hp is how fast it is pushing that hard.

we can throw some real numbers at this, if you like. it sometimes helps it make more sense.

You'd have to ask how much torque is made by a 6 cylinder 250cc motor at 5250 rpm.
That's where the curves cross. Most motors rev past that rpm. So the HP continues to clime.
So at 20,000 rpm it makes 60 HP.

Those little bikes wont pull at all under 4 or 5k.
Shit my RG500 doesn't want to pull it's self away from a light under 2500 to 3k.
FUCKING IDIOTS

Second sentence says what? Oh, it's part of a formula...

It is a standard combustion engine............for a helicopter

P.S Output power is fuel (minus losses). Rpm is merely a product of more fuel for a given time. It's not rocket science.
