There should be a .0688 for the 800

 

you need 1hp to move 10lbs to keep a perfect 1to1 power to weight ratio is it the same for torque

 

how do you get to the hp ratings on that site

 

never mined i had to read some of it to find it

 

Well, of course my "twice that" remark was WAY off in real world applications...... I was just waxing poetic..... I actually meant twice the ratio, not twice the HP. In reality if a chain drive ATV loses 10hp in the drive-train, a CV-joint set up might lose 12 or something more realistic..... but as I said that would be a guess in exact numbers ....

 

exrider91, where did you get that 10 lbs 1 hp ratio because it's wrong...

 

i know many people that built racecars,dune buggys and sports bike and they know the formal.let me expain it to you simplely like 1hp / by 10 pounds you get .1 thats a perfect 1 to 1 power to weight ratio.if you understand this well you will know that you have .1hp pushing 1 pound.even with the same gearing the car with a power ratio thats closier to .1 wil always win because their is less effort needed to move the weight.their is no power gain by running lightier only less load on the engine letting you gear highier andor get lower times on the drag strip so in simple words lossing 10lbs will be the same as gaining 1hp.

 

72 nm = about 45 lbs torq ... 1 newton meter = .737 ft. lbs of torque

 

It's actually about 53lbs of torque.

 

I herd that the 450r with the optional HRC power kit has 50hp. I don't know if it is right of not though.
