nothing.... if you take the 450s out of the picture, the Raptor is the fastest thing out there... well, I the new outlaw 525 may be up there, havent seen one yet.

 

hey guys
i have a06 kfx700 and i love it you can speculate about which bike is faster or a better ride, but the truth is it makes a huge difference if you are a big guy or an average guy. i am 280 and 6ft3 and i cant ride a raptor and be comfortable. i saddle up my vforce and its on. i searched and searched and my neighbor and ggod friend bought a 07 raptor se orange and black, it is probably the sexiest bike ever made but i wouldnt trade mine for 2 of them, doesnt mean its not a great bike its just not for me. i have dual hmfs magnum cdi box, rear wheel spacers and i can motocross it or cross country it, drag it, mud it, or hill climb it and it has never failed me yet. i also have a prairie 300 i bought new in 99, i have only spent 250 dollars on it, no complaints, my raptor 350 has cost me a fortune and its an 05, maybe the kawi can take a little more abuse. the prairie was my first atv and i didnt take real good care of it.

my advice would be go set on both bikes maybe even ride them and you will be able to make your decision, good luck and happy trails

 

Very good point... I traded my KFX for the raptor because im 6' but only 145 lbs. Raptor just fits me better.

 

my buddy is 6 4 and 160, he loves his but he still rides mine every chance he gets. i call my bike the lazy mans hot rod, i am lookin to make some spring and clutch changes do you have any advice

 

EPI maroon spring. No stall and runs great....

If you want a little stall dalton orange/ blue and the dalton clutch weights.

Both are great choices.

 

What I don't understand is how a 450cc is faster than a 700cc? I have heard it is, but it must be due to gearing or higher compression. Is this true?

 

Compression, weight, and gearing.

 

raptor is a really good drag quad
