whats the most race ready quad?

YFZ450-R. The YFZ is probably the most potent (commonly-seen) ATV on the market in stock form. It has good shocks, a well-engineered frame, and an effective EFI system on the "R" version. The engine is pretty stout right from the factory. Add a pipe, fuel tuner, and a tether kill switch, and you are just about ready to hit the track.

The Can-Am DS450's are nice, too, and will give the competition a run for its money.
 
My vote goes to the gas gas 300 HP. Sure, it has some steering issues that need adjusting but id rather race one of those than a Katoom.
 
i have rode :yfz450 full walsh build(owned it) ,ktm450sx,stock yfz(owned one) ,stock ltr(owned one) ,kfx450,trx450 ...and by far the ltr was the best and easiest to ride fast ,centre of gravity is perfect on them .feels like it will never roll
 
probably the cam-am in stock form.

but if you are gonna build it its a honda, ask anyone lol.
 
there should be a poll so we can vote on witch atv but if you are planning on buildlding it out the ass honda450r if not yfx 450 if you want a 400 my cousim is selling his artic cat 400 and it is badass he races it with the 450s and there by no means stock and he beats them most of the time
 
Apex... Not really a "stock" quad but race winning ready right out of the box.

$13k is a tough pill to swallow though
