I’ve got a honda 400ex with a bore kit that bored it out to 440cc and a pipe and little ins and outs and i got a top speed of 130mph!! so dont tell me their not fast i almost pooped my pants

thats great.. i love when people say it does like 100mph.. wtf.. are you crazy... or just on glue.. dont use a car to get your topspeed.. use a radar or a speed trap.. i have a 400ex with mods revbox.. and i doubt that it does close to 90 maybe 70 if im lucky.. but yes.. the 400ex is the best quad all around.. you can do whatever you want with it.. race. have fun. work. you can even tow stuff with a trailer kit.. so if you dont want anything fancy.. go with the 400ex..

i have a 2006 400 ex with power core 4 exaust the top speed your gonna get out of a 400 is about 70 mph if you hook a 450 to it and drag it you might go 80

All you guys are retarted, The 400EX is a dinosaur. Its been virtually unchanged since it came out in 1999. For all of you that think your 400 does 75+ then your being unrealistic, Im not not even gonna start with the kid who thinks his does 90. I’ll put it this way. The new-age 4- strokes (YFZ450, TRX450R, R450) are all much more high performance than the 400, their not even close. They are lighter, faster, handle better. The list goes on and on... These machines will do 75. Maybe 80 MaX. (Were talking stock) And dont tell me otherwise. I have a YFZ and A 450R. My first quad was also a 400EX when i was younger. Dont get me wrong the 400 is a good quad, and its reliability is unmatched, but it will not do what you guys are advertising.

dude that kid that said that his bones stock 400ex does 90mph man what are u smokin what ever it is i want some i drag race a 400ex that is all worked up and i dont evn get 85mph all that working them up does is let u get to the top speed faster intill u start playing with spockets

both of them stock a honda 450 will beat it but the yamahas 450 has more power then hondas

a 450r will be the yamaha 450

My 2007 400 ex topped out at 76 mph on the road with a car driving beside me. Only upgrade to it is a K&N air filter.

A stock 400ex doesn’t go 70-75mph it goes around 65mph and even if you add a pipe and airfilter that doesn’t increase you top speed it just lets you get there faster to increase you top speed I would start with getting a Rev Box.

LOOKING FOR A WAY TO GET MORE POWER AND SPEED OUT OF MY 05 HONDA TRX450R. I HAVE A WHITE BROS.EXHAUST,180 MAIN JET,SRP REV BOX,AND K&N FITER. I RACED OTHER 450’S THAT WHERE A LITTLE POWERD UP AND THEY WERE ABLE TO GET ME AT THE FINISH LINE ON A 100M DASH. ANY SUGGUEST. THANKS ,ARMANDO

my friend was in front of me in his car and he just started pulling away at 95 and my 400ex is stock, so it does well over 90mph

hello i live in the netherlands do you also shipping atv’s to the netherlands and what is the total price to shipping and buy the atv honda trx400ex to the netherlands

The stock 400ex goes anywhere from 70-75 mph

The dude Miguel that beat the 450R by 5 miles was they pushin the 450R or did it even have tires on it?

My YFZ450 smoked a 2006 400ex that was jetted with a yoshimura exhaust and a 440 big bore kit in it and my 450 was stock by almost a mile and i was like WOW!!

What is the top speed of the 2006 TRX400 ?

my 400 Beat a trx450r and it had a pipe jetted and it had rev box in it and i beat it by 5 miles it almost will beat a predator that is jetted and piped.

yeah my TRX 400EX goes like 36mph i pust some new muffler bearing in it. yeah i beat a 2005 Yamaha Banshee that had Big Bore carb kit, white brothers series exhaust, and a kick stand. i was like whooa! yeah I beat him by 4.8 sec. it was nuts!

billy
