what do you mean by quickest? drag race-lt 500 track-yfz 450 i dont know about highest top speed but im guessing the lt 500 has it. and if your talking about which sport atv that is currently in production, then i believe the ds 650 will take the drag race, and either the ds or raptor will have the highest top speed.

 

dont forget about cannondales

 

i dunno why, but now my zilla is doing about 81. all ive done is chnaged oil brands from motul600 to yamalube, but that cant have anything to do with it........

 

change the tires and add teeth to the front over a hundred. figurd out zilla at 102.3 but that doesn't take in wind and fat bodies.

 

what do you mean by that???????

 

if u *** teeth to the front u wll b doing ova 100mph

 

KTM520 will go over 100 stock. now. what piped only banshee will do that.

 

i want to put one of those high horsepower dirt bike engines in a quad and mod them a little bit. what a dune machine that would be.

 

EVERYONE KNOWS THE DS IS THE FASTEST OVERALL. WHY DO I KEEP HEARING ALL THIS STUFF ABOUT THE CRAPTOR. THE DS IS HEAVIER AND LESS CC'S AND STILL PULLS BY IT IN THE END

 

get an eraser u can pick wat engine u want in it suspension its crazy
