Why are you calling these wet/dry numbers curious?? When you consider for instance the C'dale, add a couple gallons of gas at 7 pounds per gallon, a gallon of antifreeze/water in the radiator at 8 pounds, 3 quarts of oil in the crankcase and transmission, 1 pound per quart, that equals 25 additional pounds. So the chart above showing 375/396 is pretty accurate in my opinion!

Now the Raptor on the other hand either has a 5 gallon fuel tank or Yamaha didn't want to tip that 400 pound limit but obviously they did!!

 

WHat if the C-dale holds 2 gallons of fuel...and less than 3 quarts of oil....and I bet it does'nt hold a gallon of coolant either? More realistic number then. The Raptor holds 3.2 gallons of fuel.

 

The cannondale is an American quad, the Japanese quads are the ones with suspicious dry weights.
Dry weight you see advertised in a magazine = whatever magic number the manufacturer wants to use (nearly a useless number to be used in your equation)
Wet weight = actual weight of a ready to run quad, measured on a scale.
You can see from ATV Sport’s measured weights, some surprises like the Predator actually being 7 pounds lighter then the Raptor. (and thats with more fuel weight to boot)

Another example is my Z compared to the Predator. When I was deciding weather I was going to buy a Z or wait a couple months and buy a Predator, I compared the claimed dry weights and saw the Predator was 43 pounds heavier. When in all actuality it only weighs 34 pounds more, and that’s with a bigger motor using more coolant, oil, and fuel.
See what I’m saying here?

 

I said this before in another post some place but any ways. There was an article in one of the magazines that for the 2002 model year Yamaha made some durability upgrades to strengthen some of the parts on the raptor. This resulted in adding 8 pounds of "dry" weight. The raptor ended up weighing in at 406 pounds dry but Yamaha never changed any of the statistics the show to reflect it. I also agree that the weight of your quad ready to ride plus the weight of the rider that's going to ride it is the weight to do your hp to weight ratio with because that's the real world performance number each rider is working with.

 

Well the new yamaha 450yfz needs to be added, I took the liberty to make an estimate of the probable horsepower for this atv. According to yamaha's claim that the the yfz450 has the highest power to weight ratio of any four stroke ever made, we can take the Cannibals claimed power to weight ratio of .1013 and multiply that by the yfz450's claimed wieght of 350lbs to get 35.455 hp. So it looks like the yzf450 will have about 35.5hp, if not more, to be able to live up to yamaha's claims. And as we all know it may have a ton of hp at the crank and loose abunch along the way to the rear wheels and not be at the top of this list with respect to that.

 

From what I've read in other forums (or elsewhere on this one), Yamaha doesn't seem to consider Cannondale ATV's in their claims. Many of the "First on an ATV" features of the YFZ400 as listed on the Yamaha site have allready appeared on Cannodale's.

 

Just out of curiosity, where did the numbers for the V Force come from? I bought one (today as a matter of fact) and it feels like it has every bit of 45 to 46 HP, but I would have thought that the automatic transmission + shaft drive would have eaten more than 5 HP (based on the 49-50 crank HP that is the accepted power output of the impressive V Force engine). Just curious....

 

looks all good and is very very helpfull. Wonder why someone doesnt put this kinda info on a website.

 

I cnt believe that the clear winner still isnt on the list

2003 Ketchum 250 318 lbs ------------ 60 HP
