ATC 250R vs. 440EX

[rippn250R]

My buddy just got a 440ex and he keeps bragging to me that it is the fastest thing ever built. He says it will smoke my 85 atc 250r. My R has a pipe, jet kit,k&n and a flatslide carb. Of course his is built up too. I havent had a chance to race him yet, so I was woundering what you guys think. Its probably a stupid question anyway.

[Lots_Of_Nothing]

i think your friend will be seeing your ass end alot

[350Xccelerator]

well all the 440ex's ive seen would kill an atc250r, if he's a good rider he'll smoke you. :?

[AirManCam]

The 440ex should chew you up and spit you out. :?

[ATC crazy]

The 440 will kill you in the woods. I'm not sure about the drags, but I would watch out...

[350Xccelerator]

ive seen a 440ex with R4 pipe, bigger carb, jets and filter woop the crap out of everything that faced it, the guy on the 440 would beat piped raptors z-400s predators and others easily, sometimes he gave the other quads head starts and he would catch up, ive never seen a quad with more bottom end than that 440ex i saw.

[badtriz]

ive raced a 490 and it wasnt that big of a deal, he did pull me on top because i had heavy ass v paddles and he was on stockers

[Manny55]

440ex would be fun to have lol.

[Manny55]

Man if I asked a question like that i would be yelled at thats gay.

Manny

[MR ATC]

faster aceleration...250R
faster top speed...250R
faster on a track or in the trails...depends on rider.

[350Xccelerator]

there is no way a 250r would have more acceleration than a 440ex. NO WAY! :rolleyes:

[groundfly]

hmmmmm..i got an idea, how about you race him, and let us know who won. :idea:

[350Xccelerator]

I dont have one, but ive seen many that'll smoke almost any 250r though

[MR ATC]

there is no way a 250r would have more acceleration than a 440ex. NO WAY! :rolleyes:


no?, and why is that?

a 250R weighs 290 and puts out about 43 h.p. with the mods he listed. it is also a faster reving 2 stroke. it also has less drag with one front wheel.

a 440ex weighs about 360 and puts out about 40+ h.p. and is a slower reving 4 stroke. it has more drag with TWO wheels.

explaine to me why it ( a 250R ) would not have more acceleration.

[350Xccelerator]

rippin250r race your buddy then tell us how it went and don't lie, get pics because i think that the 440ex will beat your 250r, i like 250rs but the 440ex is too much. :?

[AirManCam]

Mr atc. A stock 250r doesnt have 43 hp. And the 440ex would kick the rs ass the only place the r would have a chance to win would be in acceleration. Manny make your ex a 440. :twisted:

[Levithan]

Hehe, well i personally think that a quadzilla would smoke either of the 2. Heh, just my 2 cents. My friend is gonna get a quadzilla soon :twisted:

[Darius1502]

What is a 440ex? Thats not a bored out Honda 400ex is it?

[AirManCam]

I had a quadzilla. They will run about 82ish stock :twisted:

[350Xccelerator]

What is a 440ex? Thats not a bored out Honda 400ex is it?

Yeah it is.

well the 440ex i saw would kill a 250r in acceleration, the guy on it would give other quads head starts and he would catch up!

[ATC crazy]

Just because it has more cc's dosent mean its faster...

[TimSr]

More guys racing the 400EX at the local MX tracks here have the 440 big bore kit, than dont. If I get taken on the holeshot by a 440EX, its not by much, and its about 50% of the time on my mostly stock TRX250R. The guy on the Predator usually gets the holeshot, just in front of the couple of guys on highly modifed TRX250R's, and the Banshee guy. Thats is until last week when a guy started running his new Yammie. Its stock other than pipe, and he ran right with the Predator to the first corner.

[MR ATC]

Mr atc. A stock 250r doesnt have 43 hp. And the 440ex would kick the rs arse the only place the r would have a chance to win would be in acceleration. Manny make your ex a 440. :twisted:

AMC, re-read what i said,...

"a 250R weighs 290 and puts out about 43 h.p. with the mods he listed"...

keywords THE MODS he listed.

so now you have two machines with about the same H.P. but one is a lighter (by about 70lbs.) 2 stroke. listen to what your saying do you really believe it. :rolleyes: :rolleyes: :rolleyes:

[250rmanfmf]

you can have my R to race him and then you'll beat him no question. I have a drag 85 250r. I agree with Mr ATC. He has raced them before. If anybody knows he does!

also depends on who built the motors on both bikes, one could be dialed in perfect and one could be running like trailprotrailprotrailprotrailprotrailpro. That will make a deference.

[Mike Fort Laud]

Boy all of you must either be high or have never ridden a Honda ATC 250R. I dont give a crap how bad you make a 400EX, 440EX,or how ever many more cc's you can squeeze into that 4 stroke piece of junk. You can take any new 4 stroke 4 wheeler off the showroom floor and put whatever bolt on items you can buy and after you spend all of that money I will then show you how an 18 year old 250R will smoke your ass. And as far as those Banshees go I have out run many of those unless they have motor work and a lot of money sunk into it. And about that acceleration you guys want to brag about on your quads,just think about all that extra weight you have to hold the front WHEELS down. Unless I sit on the handlebars and put my feet on the front fender my light front end will wheelie to the sky,so us 3 wheelerguys have to feather the clutch a little more. I pop the clutch then let of the gas for a split second then nail it and let that power band pull me right past you about second gear,then buy third gear you get to read the C-YA sticker on the back. The only thing that has ever out run my 250R are a couple of highly worked Banshees. But the best part is that my R is not highly modified,But after I do some more motor work on it I may need wheelie bars.. 4 STROKE QUADS SUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[rippn250R]

Well,i went down to his house to see the 440ex, and to race him but he said that he doesnt want to race me now because he just rbuilt the engine and he doesnt want to blow it up. Maybe hes just afraid i might beat him.Its a quick quad but I like the 2 stroke power better!!!

[sandrooster]

... he said that he doesnt want to race me now because he just rbuilt the engine and he doesnt want to blow it up.

Sooo, whats he gonna do with his rebuilt ride. Take pictures for the web?

[N8s250r]

My buddy had a completly bone stock 1985 atc 250r and raced a 400ex that was piped and had a k&n air filter. the race was neck and neck the whole way until at the end the 250r hit 6th gear, pulled ahead, and one the race. so with that being said... i think the 440 will beat the R but it will be pretty close, neither machine will be blown away. :D every one has a different opinion. everybody's machine is faster than the other guys simply because its there machine. even after you may beat the opponent there 4 million excuses that they come up with. :-D

[MR ATC]

so with that being said... i think the 440 will beat the R but it will be pretty close, neither machine will be blown away. :D every one has a different opinion. :-D

i don't think i know your wrong on this.

stock 250R puts out about 38 h.p. and weighs 295 lbs

stock 400ex puts out about 28 h.p. and weighs 375lbs

stock 350X puts out about 28 h.p. and weighs 320 lbs.

pipe and jetted 400ex puts out about 30-32 h.p.

a 440ex puts out about 40+ h.p.

a piped and carbed 250R outs out about 42 h.p.

now a stock 250R will walk away from a 350X. a stock 350X is slightly faster the a stock 400ex. there is no way a 400ex will hang with a 250R. even a 440 ex will not be able to beat a 250R.

now this is the important part ,the rider on a 400/440ex may be better then the rider on the 250R but that does not mean the 250R is slower.

if you still are not convinced of this, look at the TRX250R that is faster then a 400/440ex and a TRX 250R is slower then a ATC250R.

LONG LIVE THE KING...ATC 250R

[md1985250r]

AMEN ....MR.ATC

[Lots_Of_Nothing]

hmmm idk what you gys are talking about, but i rode my friends 440ex, with dg exhuast, wiseco piston, and a few other things, and it didnt seem like very much at all

[rippn250R]

I'm running 18in. tires and a 38 tooth rear sprocket. How does that effect my speed/acceleration. Im guessing i might loose alittle top end.

[smokinwrench]

I just put 18" turf tamers on my R. I have 13/39 gears. It is the same for acceleration. I have the exact same top end as a stock 2003 Raptor. I was very disappointed not to be pulling away from him. My top end is very slow compared to before. I will never buy any more 18" tires.

Josh

[Yardbird]

I agree with Mr. ATC that the 250R will walk away from the 350X. My buddy bought a new 250R and I picked up the 350X both brand new in 85. We were both same weight and comparable skill. Every time the 350X would jump out....1st then 2nd gear and by the time I was halfway through 3rd that 250R had wound itself up and would go by easily and keep pullin away.
I still have mine (didn't ride it for 14 years) and haven't raced any 400EX's with it but they usually don't follow me up the steep dunes and such. If what Mr. ATC says about the 400EX being similar to the 350X in power:weight I don't think an extra 40cc's of four stroke power will be enough to take the Mighty R. Especially if it's been modified somewhat.
I've been thinking of having the Powroll 430cc package done to one of the 350X's I've got. Anybody had any work done by them or know of anyone using them? http://www.powroll.com/printer_h_atc350x.htm It does look interesting to say the least as for modifying the 350X.

[TimSr]

if you still are not convinced of this, look at the TRX250R that is faster then a 400/440ex and a TRX 250R is slower then a ATC250R.


Exactly my point.

[Kilborg]

As far as raw speed and horsepower to weight ratio, the 250r reigns supreme. Ill take my 250r throw a couple bucks into it and smoke most any 400ex you can build.

[trikerider2oo7]

Who gives a rats @$$? trikes are better than quads... So lets leave it as that.

[NOS_350X]

ok take a look/ride/race the new yfz450 and trx450 they will smoke your 250r unless you have taken a 2ed morgage on trailprotrailpro house to pay for your modds

[MR ATC]

for pure aceleration and top speed i'd put a piped ATC 250R up against those two anyday.

[Kilborg]

Look at it this way....

Your comparing apples to oranges. If honda put anywhere as NEAR as much technology into the 2 strokes as they are with the 4 strokes, it wouldnt be a comparison. We would have 70 horsepower STOCK 250cc engines (naturally aspirated). The new breed of 4 strokes are in a very high state of tune from the factory. The aftermarket will be hard pressed to gain much more power out of what is already there with the traditional methods. So basically, it took honda 20 years of f1 racing and 200 extra cubic centimeters to make a production bike that could hold a candle to the old, decrepid 250r. Great job, honda. Yes, I'm well aware of the differences between 2 and 4 strokes (something I have been very seriously studying since I was able to read and turn a wrench).

[kdagenais]

Just something to think about is on motocross (Dirtbike) racing they allow the YZ450F & CRF450R (4 Stroke) bikes run with all of the 250 2 storke bikes in the same class. If the more cc's was that big of a differnce the 4 strokes would have a separate class in its self. Like I said in the beginning just something to think about in the terms of cc comparison.

[TimSr]

May be the case where you race, but AMA, and CRA both have 4 stroke only and 2 stroke only classes which are considered advanced classes. Beginner quad classes are mixed, and Senior (30 and older) classes are mixed. They also allow 300EX and 250X to run in the 200cc Blaster classes.

[theeechozen1]

my buddies 452ex with edelbrock carb, yosh pipe, running race gas is the fastest slowhundred ex i have ever ridden, very fun bike, but my R is just piped and filtered on p3 wiesco and I pull about 1/2 bike legth every time I shift...you have to win the lottery to make those things REALLY fast

[Manny55]

Mr atc. A stock 250r doesnt have 43 hp. And the 440ex would kick the rs arse the only place the r would have a chance to win would be in acceleration. Manny make your ex a 440. :twisted:

AMC, re-read what i said,...

"a 250R weighs 290 and puts out about 43 h.p. with the mods he listed"...

so now you have two machines with about the same H.P. but one is a lighter (by about 70lbs.) 2 stroke. listen to what your saying do you really believe it. :rolleyes: :rolleyes: :rolleyes:


The 250r is acutely almost 90 lbs lighter then the 400ex, the ex weighs 377 dry weight. And AMC i'm thinking about making my 400ex a 440 but it cost a lot of money 440 kit $200, then i need to get a bigger carb not sure how much those cost then for the labor for boring and the 440 kit installation. Its pretty spendy.

[Manny55]

Well thats your opinion. Talk is cheap punk, banshee's would smoke a 1985-86 250r any day stock for stock.

[MR ATC]

Well thats your opinion. Talk is cheap punk, banshee's would smoke a 1985-86 250r any day stock for stock.


No, it's FACT.

and Manny, Mike is no "punk" he is one of the most knowlegable people here and has forgot more about motors then you know.

a stock 85/86 ATC 250R will eat a Banshee up for lunch.
a stock TRX 250R will smoke a Banshee and the TRX is slower the the ATC.

you can now remove your foot from your mouth.

[PLJ.]

We should settle this by the weekend. My brother-in-law sent out his 400EX top end to have the 440 treatment, full porting, polish, valve job, cam, I think to someone on the West Coast, in addition, Hinson basket, Performer carb, White bros E series, Sparks ignition, etc. "Total cost well over $2,000.00" He should have all the parts back by the weekend. I have a bone stock 85 ATC250R, stock gearing, tires, pipe, etc. His 400 with a pipe, jet kit, k+n never proved any match for the ATC. We will see soon. I hope that he doesnt beat me, for I will have to ruin my "stock" "cherry" with the Trinity Drag Pipe, FTZ Reed cage, 37mm PJ Keihn and the new K+N Filter all of which are sitting on my bench ready to go if a four stroker beats her. Will post results.

unless you can get this on video im not going to believe i dont care what u say.

[250rmanfmf]

MR ATC IS RIGHT!!!!!! Banshee is slower than both 250r's, also the banshee handles like trailprotrailprotrailprotrailprotrailpro compared to the Trx 250r. the TRX 250r is a way better bike. Expericenced riders/racers know what they are talking about! Believe it. if you dont, go buy a stock banshee and race a stock 250r and tell me who wins!

[Ace Mon]

Will a 440 would kill a 250r ??? First of all its a rebored bike . I have a 250 r with a 300 kit 42 mm carb paul turner full race pipe and lots of extras . So in the end you are pitting a modded machine against a stock250 r ? This hardly seems fair by comparison .

[TimSr]

Believe it. if you dont, go buy a stock banshee and race a stock 250r and tell me who wins!


I have a stock TRX250R, and my brother runs a Banshee setup strictly for low end. On a drag, I take him until he puts on a passenger to reduce wheelspin, and then its not even close, the Banshee is way out front. On a MX track, sure the R toasts him.

But since this post is ATC250R vs 440EX on a drag, My stock TRX250R runs about even with the 440's, which I test almost weekly at the track, and since the ATC250R is the same thing as mine, only quite a bit lighter, Id have to conclude its probably got an edge on the TRX, and an edge on the 440. With the Raptor and Pedator out there, the 440 is no big deal, and cant pull the holeshot with either one.

This whole thread is kind of a dumb armchair racer useless debate anyways. How 'bout you guys just race, post the results, so we can all shut up already.

[theeechozen1]

I am gonna disagree with the trx being faster than a banshee stock for stock in a drag race..the R will hook up and get the jump but by the time you hit 3rd (on decent hard pack) the shee will have traction and fly right by the R and the trx will not catch up...period
I beat piped banshee's on my atc250R all the time drag racing, but that extra 80 some pounds is plenty enough to slow you down

Your right one of my neighbors has a MINT I mean mint trx 250r I think its an 87 and I raced him he got me off the start and then I cought up and passed him I only beat him by about 15 feet thats not much at all but its still winning ;)

[ATC crazy]

A Banshee has a higher top speed than the TRX, but the TRX will get the jump on the 'shee, and the TRX will SMOKE the 'shee everywhere else....period ;)

[AirManCam]

If I could Trade my 03 banshee for a MINT trx 250r I would do it in a heart beat! :twisted:

[theeechozen1]

i dont know about everywhere else, I mean we are talking drag racing here,
hard pack- trx will take the banshee but not by the end of the race
sand- banshee will take a trx the whole way after first gear
street- the trx better have NO2 :D
