Personally I think most of you don’t know anything. The whole 400ex vs 700 raptor really depends on the rider. To truly tell which is faster and by how much the only accurate way is to have a computer dyno run so there are no mistakes no weight differences from riders no terrain changes. Back 13 years ago I had a stock 93 Mitsu eclipse and drag raced a t/a. The t/a should have raped me but he lost because he couldn’t drive at all. The rider is the biggest difference to all of you who claim you can outrun this bike or that one. As far as it’s concerned the fastest quad produced is one most people don’t even know about. The Suzuki quadzilla with a monstrous 500 two stroke they will outrun e Rey stock quad out there. They quit making them because people wouldn’t buy them because they outpowered the riders and were not controllable. As far as racing. I have yet to lose to a stock raptor or yfz with my modded 400 ex. I’m a professional builder and know how to utilize the power my quad puts down. And most of the people that ride raptors are in the 180 up weight range I weigh 128 and am 5,7 so my quad is not bogged by me. Makes a huge difference. I can outrun my cousins 660r that has a jet kit. K&n and ct full exhaust easily. He weighs 427 pounds see my point. Get over yourselves and learn your facts before you say something otherwise save yourself the trouble open mouth insert foot.

Most of have no clue what your talking about. First off if you know how to ride and build your quad correctly a rev box will not kill it. Second a 440 turbo is a Timebomb. And third when you take the weight gearing and hp of the raptor compared to a 400 they end up having a 1 hp difference in power to weight ratio. So they are pretty much both the same power. My 400 is modded. 03 400ex 426 13:1 JE piston. Stage 3 hotcam. Ported and polished head with oversized valves five angle face. Ct full ceramic exhaust. Moose unlimited rev cdi. Msd ignition coil. Billet clutch hub. Moose clutches. Fcr 39 mm carb dynotek jets. Hotrod crank rod and bearing kit. Dura blue rear axle moose fat bars. Billet case saver. Esr shiftlever. Fox suspension. Ac bumper Regina z ring chain and sprockets and a dyno hp total of 63 hp to the wheels.

dont get a rev box they pretty much kill ur 4 wheeler good for the time they let ur four wheeler run thts about it, if u think not tell me and those ones about the 250ex and 90 r jokes im makein fun of some of the dumbasses on here tht r full of them selfs and there 4 wheelers

and any fag who says yamahas are more reliable than hondas dont no nothin about honds so shut up

the raptor may out run the 700xx but honda has better riders than yamaha in baja ,honda 700xx won in atvs ,and crf somethin i forget won the dirtbikes

and a preadtor 90 tht blow any of urs away to it goes 30 stock tht how fast ur 400s r they probaly dont even run aand even if they do u probaly couldnt ride worth musk ox ass. u dum fuks and hondas are the best besides urs because. im big and bad and run high octane fuel u dumb fast 400 guy on page 2 ur stupid

hey my friend has a 250ex stock and ita blow ur y asses away it goes 10-15 stock

to tht "fast 400" guy on page 2 ur stupid face it i dont care wat kind of fuel u have in a stock 400 anything it wont go 145 mph,and u sure its not a stock gsxr 600 motor gahh lee!!!

to yamaha fans,
all you have is a yfz450, the raptor . any 450 and keep can keep up/beat a raptor. btw a raptor has like 700cc witch is 250cc more the a 400ex and a 400 can keep up. honda is the best and always will be!!!

any one who thinks a 400ex is going to do more than 90 with out a coustizm 500 kit in it in the dumbest person ever and should be shot in the

the 400 might not but check out the 450 ex it will keep up with the new raptor

the raptor 700r would walk over the new honda 700xx all day no matter what the raptor is an all around better atv

hey im 14 and i just got an 04 honda 400ex with itp tires and rims and a blindstar bumper and grab bar and fly handlebars. do any of you boys have some tips for me to soup her up a lil bit?

good luck smoking my dad on his yamaha raptor 700 with a k&n you wounldnt even smoke a stock yamaha raptor 700
