An agreement between ATV manufactures was established a few years back saying that an atv can not exceed 80 mph stock. If that agreement was never made sure the 700R and DS650 would proably be getting up to 80. I think a stock Zilla on a good day can hit the 80 mph mark if its properly tuned, but is there really any stock Zillas left today?

 

Then you have some internal work done, because even a piped raptor wont consistantly beat a stock zilla.

 

My raptor is piped amd jetted and I can beat a stock zilla,but I never raced a pipe zilla.

 

ehh, I dont know about that.

I'm guessing special circumstances if it actually happened. And just because you beat him once doesnt mean you're faster, its when you can repeat such a win over and over again with multiple different competitors.

 

Raced 5-7 times in 600ft....me beating him by 3 bikes.

 

As for the top speed: Before I got my 89 lt250r I briefly had an 86, my brother was on his 87 with same mods as my 89. We left a pit and my cousin was in his car clocking us. My brother shot ahead of me (I had to shift 1st to 3rd-bad second gear) and my cousin clocked him. He was going 75 on a 250 stock gearing but he had 22s on it. I'm not sure if they came with 20s stock, but my 89 had 20s on it when I got it. I'm pretty sure I remember seeing 22s for rear tires on specs on top of air box. Anyways, it the 250 does 75 then the 500 has to go faster than that.
PS It definetely doesn't take a mile to wind it out. Probably around 1/4 mile.

 

Maybe he can't ride the thing, try and swap riders.

 

Maybe you are right or maybe I am just faster.

 

On atv sports latest magazine it has a whole 6 pages the zila and the top speed is 76mph. the pages are from 58 to 63 the top speed is on page 63. its the november mag.
