Piped both is a different story, but stock the raptor beats it in top speed, it also beats the YFZ. And yes brad, the predddy does beat both too. And also, kawasaki never said anything about coking out with a new 450 did they? I know suzuki is but notkawa.

Trust me when i say i don't need to be told about comp ratios,carb,etc.I am not some teenager with big dreams,no sense.I am 32 years old and i have a built drag car,hi-po watercraft,snowmobile,zr2 s10,450r,
and i have logged over a million miles driving truck.Not bragging,just letting you know where I am coming from.
Let me break it down for ya.
CC's 450R=449/YFZ-439/raptor-660 comp ratio 450R 10.5.1/YFZ 11.9.1/raptor-9.4.1. max rpms 450R 9850/YFZ-10750/raptor-9200 Weight 450R-350/YFZ-350/raptor-399 Carb 450R-42mm keihin/YFZ-39 fcr
keihin/raptor-twin 33mm mukini bsr...
Now,obviously a big cc engine does not rev out as high as a smaller one(reciprocating mass)whether it is a
quad,car,etc.As far as comp ratio the 450r is middle of the pack.The weight difference is minimal.So what I am saying is the fact that the 450R will hang with both of these quads says something about honda engineering.I don't doubt you may have beat a 450R,but iI have seen a 450R beat a YFZ and many of your
fellow yami fans say they can beat a raptor.When it comes to top speed the raptor has always been known to do 74 mph give or take a couple mph,so unless something has changed that drastically how is it
that you think they are so much faster.I have not radared mine yet but from what i see and hear 450R is around 75 mph and YFZ is 73-74.I am talking stock here,no mods.With mods there are too many variables to consider.This not a flaming,but i have read so many threads dissing the honda and i feel it should be given the respect it deserves.
Just my.03 cents..keep the change!
