If only Honda would produce their version of a 500 two stroke quad.I would bet that thing would eat up zilla's.Oh well,i don't think we will ever see another high performance two stroke quad produced.[img]i/expressions/face-icon-small-frown.gif[/img]

 

i remember the husaberg enforcer!! but what about the rebel star full race quad? i bet that mighta been faster than a zilla. or maybe a Tiger super 4. i heard those were fast *** too! both the rebel star and the tiger had 250 2 stroke rotax engines so who knows...

 

the fastest? Sbarro 1000...what about 145hp and 125mph+ to speed???

For the more "normal" (read mass-produced) quads, the quadzilla was probably the fastest...

 

And don't forget about the Ravage 1000 that you get for beating "pro-career mode". [img]i/expressions/face-icon-small-wink.gif[/img]

 

Quadzilla's stock had low 50's HP, put a pipe,and reeds on it and they are close to 60 HP. They were detuned by taking the RM500 motor and reducing the port size by about 1/3, lower the exhaust port to produce more bottom end, and putting a more restrictive exhhaust on. If you look at an 86 CR500 motor (The most powerful CR500 ever) it had 65 HP stock

 

Are those HP numbers at the crank or at the rear wheels. I'm guessing at the crank.
