Raptor660R/YFZ450

im pretty sure the yfz tops out at more like 73-75 and the raptor at least 75-77. in those ranges. think about it... raptor<u>660</u> yfz<u>450</u>. displacement has a lot to do with top speed. bigger dispacement, more torque to spin the wheels faster and therefore have a higher top speed. gearing is the #1 speed restraint but if you dont have usable power or enough power to get there then whats the point. who cruises around at 90 miles an hour? top speed/ acceleration can be changed simply by changing sprockets size or tire diameter. your not going to get a really consistant # for the top speed of any quad. it depends on other things like elevation, how well your motor has been maintained etc. anyways, thats it...

In the real world we ran 3 honda 450rs and 2 yfz's and 2 raptors. and the raptors ar a couple MPH fast then all of them. in an all out 2 mile run on flat sand. tests were conducted last weekend in florence, Oregon. but in reality it dont matter. its whats the most comfortable to you, what power suits how you ride.
