does anyone know what it is? | ||

If you use a wet weight of 465 lbs and a rear wheel horsepower of 124, it comes out to 3.75 lbs/hp. If you make it more realistic when comparing to a car writeup in a magazine, you should use the crank hp and add the weight of the rider. Using 146 crank hp, and a 180 lb rider it comes out to 4.42 lbs/hp. | ||

just to give you a comparison a Ferrari enzo has 4.56 pounds per horsepower. | ||

Some math wiz do a lbs. per HP per $$? And based on fire sale price of say $6500? Stick that next to the Ferrari deal. | ||

.00000228=2.28*10^-6 lb/hp/dollar-ferrai .00068=6.8*10^-4-lb/hp/dollar-buell | ||

The Enzo is also rated at 8mpg combined  | ||

Ariel Atom = 4.01 lbs/hp, unless you opt for their new V-8 version with 500bhp. Then it's 2.41 lbs/hp The Enzo is so 2004! | ||
| Dktechguy112 |
wow, that's the first car that has beat a sportbike in power to weight. plus the ariel atom is around $30k? and the enzo is 2 million. | ||

The 300HP version is at least $70K, the 500HP is a LOT more In light vehicles you need to count the driver/rider because that will be more accurate.. unless someone weighs 2lbs That's the only 'advantage' of a car, the driver won't affect a lot the ratio, in a bike it does, and sometimes A LOT | ||
| Duphuckincati |
But the Ariel is a car with a motorcycle company name! (look it up kids) And Dk, thanks for the math. But my ignorance prevents me from a clear understanding of the bottom line.? | ||

I think the Caterham Levante probably completely owns the power to weight ratio title though, 1.35 with the optional 1000hp V-8. | ||

A Top Fuel Dragster weighs 2,225 pounds, produces 8,000 horsepower...that works out to 3.59 Horsepower per pound....the fuel economy thing is out the window at 64 gallons per mile....and maintenance is steep at 60 to 80 thousand dollars per mile... But that is the King Daddy of tire driven power ....My old antique air cooled 2 valve dragbike made 2.18 Lb/Hp | ||

.00000228=2.28*10^-6 lb/hp/dollar-ferrai .00068=6.8*10^-4-lb/hp/dollar-buell if you look at the values, higher is better in this case, so the buell is higher by a factor of about 3*10^2, or 300. the math essentially says that the ferrari may be close in weight to power, but when you factor in the cost, the buell is 300 times better! | ||

Well the space shuttle has 37 million horsepower and hauls 240k lbs at liftoff. So thats 0.00648648 Lbs per horsepower, or 154.1 HP per pound | ||
| Fast1075 |
I thought of that before I posted the dragster thing Froggy....But I figured I would stay with piston engine and friction drive...good point tho....  | ||
| Imonabuss |
Gotta put the dollar factor into that space shuttle equation though, Froggy... | ||
| Dktechguy112 |
and the fact that it takes a multi billion dollar gov facility to launch it, a 300 million dollar plane to fly it back to the launch site, and not to mention the maintenance bill. | ||
| Froggy |
At least it gets 7.64mpg including all the time coasting around in space and re-entry.... | ||

only when they can't land it back here in Fl | ||

| Duphuckincati |
Thanks Dk, my math was off since I think a Buell is a bazillion times better than some sissy Ferrari! But 300x is ok. | ||

I'm fairly certain that the wet weight listed on Wikipedia & elsewhere is wrong... It should be 420 lbs wet. The Weight:Power ratio would then be 4.11 Lbs/HP assuming a 180 Lb rider. See my entry on the Wikipedia Buell 1125R talk page for calculations. https://en.wikipedia.org/wiki/Talk:Buell_1125R |
