which one is the true horsepower champ? this could get ugly.

 

LOL Roost, JUST when things were startin to cool down you start this. Your ratings gonna end up back to 1 again. lol

 

I try my best.

 

How many years did they make the YZ 490? I know my neighbor used to have an early or mid 80's model CR480 and it was bored over and the guy who bought it from him was driving it down the road in 1st gear at 35mph and got scared when he put it in 2nd so he went back to 1st. It has rediculous power.

 

The answer is 100% positively the KX500.

It is known to be the fastest off road bike ever.

 

Check this out, a 700 2 stroke!!!

ATK 700 Intimidator

 

Ah yes, I remember that.

There was talk about putting that 700 motor into a quad frame a while back.
That thing would surely take the crown nowadays.
