approximate Power-toWeight Ratios of all the Sport Quads !!!
#73
well i know the tecate 4 is overweighted in the chart. kawasaki has it listed at 328, and there are so many horsepower numbers off i dont even know where to begin, why cant you use hp numbers from the crank???????
the weight of all these quads can be found at www.offroadhaven.com and they are direct from the manufactuerer. as far as the hp numbers are concerned it would be much easier to find the numbers at the crank/flywheel

He said he gathered the numbers from magazines and websites so that is where any inaccuracy comes from. To be truly accurate you would not only have to have all the numbers at the same place like the crank or the rear wheels but they would have to be done on the same dyno. you would have to at least know that they were all done on the same type dyno since one type gives lower numbers than the other (superflow). Even then if you did them on the same type of dyno but in different parts of the country with different elevations/climates you would have different numbers. I think DSAPP has done a good job for tossing it together without making a major project out of it. If you can find better numbers go for it I would love to see the list be as accurate as possible and I'm sure DSAPP would too.

yeah!
thanks Dirt Diggler
I'm trying
and yes.... no one cares what the horspower is at the crank..... it's the HP to the ground that makes you go

The comparison of the quads dry weight to its approximate horsepower is interesting, but not quite accurate.
Japanese manufacturer claimed dry weights are notoriously lighter then they actually are, and bigger engines use more oil, coolant, and gas then smaller ones, none of which are included in claimed dry weights.
You would need to weigh each quad wet, ready to ride with equal amounts of gas in each.
Another problem is that you are not considering the weight of the rider. A quad like the Blaster looks like a real hot rod until you put a 175 pound rider on it. Then its lower HP number is more obvious.
Do the same chart with wet weights and throw in a 175 pound rider for each and your numbers would be much closer to reality.

Just some interesting dry weight claims compared to actual wet weights I thought you guys would find interesting.
Quad claimed dry weight / actual wet weight
DS650----------- 470 / 516
440 Cannibal--- 375 / 396
400EX----------- 375 / 399
Z400------------ 372 / 410
Predator------- 415 / 444
Raptor---------- 398 / 451
Banshee------- 386 / 425
Wet weights were measured by ATV SPORT magazine and were with a full tank of gas.
