If any of you are following the Thread titled "banshee vs predator response to idiots" posted by our one and only Sparky (2004ds650), you will notice my same responce. But since my Heart belongs to this Thread, I had to put it here too. [img]i/expressions/face-icon-small-happy.gif[/img]




Hey 2004ds650, You do understand the difference between a 2 wheel Motorcycle and a 4 wheel ATV, Right?

That's right, 2 wheels!!! Now on with the lesson.

First off, you are comparing Apples and Oranges. Now before you head to the refridgerator to compare the two, what I mean is that they are 2 completely different vehicles (Motorcycles & ATV's). The motor in a quad, has to have more TORQUE than a Motorcycle, because it not only has more weight, but due to the 4 wheels, and the overall size, it has more resistence (Rolling Mass). When you tune a motor to give it more Torque, it tends to suffer in the HP department (Read on to find out why you can't just have both).

A motorcycle, because of it lower resistence (Only 2 wheels) and less rotating mass, doesn't require as much Torque, and therefore can rely on HP to get the job done.

As with any motorized vehicle, you can do all kinds of things to increase both Torque and HP. At some point however, (Here is the part about not having both) you get to the point where Reliability and Safety becomes an issue. The Manufacturers need to build Reliable, SAFE machines to sell to the public. The Aftermarket Companies then take over giving you the option of increasing the performance of your quad. How far you take it is up to you.

Now be sure and study the information I have given you, there May be a Test, and go ahead and eat both the Apple and the Orange, fruit is good for you.

 

oh great, it's the whole "put a car engine into a truck" debate. *bah*

 

Just stating the FACTS.

 

my hp numbers arent wrong. different dynos different days. i read the crf has about 50 at the rear wheel, 54 at the crank. if ur going to compare hp numbers, do them both on the same day on the same dyno

I know, it's just that thread-starter started talking solely about peak HP and not torque curve characteristics.

 

they are weak every where.

 

if i remember correctly from what i read, the tecate was the fastest 250 2 stroke. it used a kx engine. now who says they dont have enough torque? heres proof

Since the four-wheeler weights in a 100 pounds more than the KX250, the KXF would have to have some serious mid-range to rocket from corner to corner. The Tecate-4's Kawasaki Integrated Power Valve System (KIPS) has been revised to provide a better mid-range hit; different gearing in the KIPS brings on the mid-range hook faster and longer than the KX250. Also, the KX250's 38mm Mikuni didn't offer enough mid-range bark, so a 34mm Mikuni took its place on the KXF.



Any builder who has tried to slip a motocross motor into an ATV will tell you that vibration is a nightmare. Would you believe the vibes froth the brake fluid and render brakes useless? Kawasaki added a water-pump-driven counterbalancer to the KXF250 to help reduce vibration, but the remaining resonance is still noticeable and a tad fatiguing.



Other KX-inherited motor features include the Fresh Air Intake System, which draws in air from in front of the gas tank and channels it to the airbox via the frame backbone; fiber reeds; a reed power booster and a six-speed transmission. Although the expansion chamber closely resembles the KX250 unit, the Tecate-4 is equipped with a heavy, flow-robbing muffler. For trail ridding, the stocker provides a quiet exhaust note, but racers will junk the canister for a lighter, better-flowing aftermarket silencer. As delivered, the 249cc two-stroke single puts out 42 horsepower, and the KXF boasts a 90-day limited warranty.

the only reason it needs more torque is for weight, but u dont feel the extra torque because its taken away by the weight. 42hp? hmmm sounds like kx numbers

 

What in the Sam Hill does all that gibberish have to do with anything?

Put down the Magazine, you're Scaring me.

That is the first half way intelligent post you have ever made, Too bad you stole all that enlightening info out of some article, and it still does nothing to prove your statement that, "Raptors are Slow"

Oh by the way, that's Plagiarism (That means copying someone elses writtings without crediting them).

 

ok i kinda get his pt.. that he WAS trying to make but to make it more clear he made himself more dumb.. he was trying to say that stock quads are slower then stock quads like a recon to a rincon and a 250ex to a 400ex.. and a blaster to a raptor.. but he was tryin to state that if u took a blaster and say modded to the max it would be a raptor modded to the max.. but thats wyhen he made himslef sound more intelligent then what he is.. cuz no way u can beat a mod rappy with a moded blaster.. and the raptor is not slow compare it to a warrior one of the most reailable quads made ti aitn gonna beat a raptor not with only 18hp with some mods it might touch it.. or say like ur Ds its not gonna beat a Suzuki Quadracer 500r or Lt500r or Quadzillia all the same thing 3 diff names.. and does QuadZILLIA mean ne thing to you. zillia is someting huge and engoumous and the zillia was the fastest prodcution quad ever made and still is..
