im planning on building a mildly modified 250r...what speed do normal 250rs with pipes do?how would they get on against a 450r or 700r stock

[leager-n-ky]

I beleive honda used to claim 69 mph stock, but it is going to depend on what pipe, what gearing, and carb, etc..... that you use.

fmf pipe....how could a 250r keep up 2 a raptor 700?

[Honda 250r 001]

a fmf piped 250r would NOT keep up with a 700 raptor. im sorry but its just the truth. Get a esr trx 5 center mount. www.esr250.com

To keep up with a stock raptor (no pipes or anything), you will need some work.
For example.. A few years ago I had Paul Turner 89 race pipe, 38A/S (pump gas) K&N, Lightened flywheel, cleanup porting, stock bore, 13-39 gearing, (tried second and first gear starts). I dragged a guy on stock raptor up a mellow hill a bunch of times. He would pull me a minimum of 1 bike length out of the hole every time. (More than that with first gear launches). I could not pull him in, I would be hitting the top of fourth gear at the end and he would always have me by 1 or 1/2 bike lengths....
My motor was feeling a little low on power (probably had the same piston in it for 7 years, when I rebuilt it I had to have it bored .20 over instead of .10 to clean up the cylinder), and I had a hole in the exhaust from the mounting tab ripping apart though..


My wifes bike on the other hand has an FMF fatty, 38 a/s and would probably be dead even with that raptor. (she also has a +4 swinger)

hope that gives a little perspective.

I can add a little insight but only with moded 660 Raptors. We have 3 250Rs and 2 Raptor 660s we go out with.

Both raptors have all the bolt on mods and pipes.

2 of the 250rs are stock but have pipes (1 FMF and 1 PT race pipe) Both will pull the Raptors in a drag race.

My bike will destroy the Raptors like they hit the brake. I have a 275cc PC2000 with PT Eliminator pipe setup. I never counted the bike lengths as they are too far back to count while trying to slow down :)

I did have the privledge of racing a modded out YFZ450R Yamaha the sad thing is the Raptors did better.

I know the 700 raptor is faster stock than the 660 but hard to believe it would stay with a modded 660.

Well, when I had my old cylinder, it was a stock cyl. bored to 68mm, 36pwk, boyeson rad valve, FMF SST pipe, and I drag raced a few 700 Raptors and I got beat by anywhere from 2 to 4 bikes.

I'm hoping with my new set-up, I'll be a little different. But then again where not comparing apples to apples. 700cc's should outrun 250cc's!!! Let me have a 700cc 2-stroke, then we'll see who's out front.

wow guys you must suck, I have never had a problem hanging in there with a craptor 700, stock trx250r goes 84mph clocked! this is bull... Raptor makes about 40hp stock( http://www.ctracing.com/raptor_700.htm ) blue one is stock hp, the trx250r has 37-38 stock, with a pipe and reed set up well into the mid 40's...

[mcboomport]

you didnt read the posts very carefully did you.. what all is done to your bike since you dont suck and all of us do.

what do you mean hanging in there with a craptor? No one said they have been destroyed by one.

[05LSR250R]

As far as Craptors go..........a couple guys I ride with own them. One is a 700 and one is a 660. I destroy the 660 in short order every time!
The 700 I can beat, but only if the drag race is about 300 feet! The 700 slowly starts to creep by once were both tapped out! However, I completely own his *** till about the 300 yard mark!:devil:

[factoryX]

at least somebody gets it....:o

nto the mid 40's... Who said anything about the 250r going 84 mph clocked??

[factoryX]

a stock 86 atc250r trike will hit 84-86mph stock, And I am saying that since the trx250r has the same motor but with more wieght, I'd say around 80-84mph is correct. the 250r trikes are nuts.

And you must be nuts too!! The atc 250r does 84-86 mph stock??????? LMFAO

[86 Quad R]

lmao! rof even. i've got an ATC sitting in the shop floor as we speak that will cruse at 92 mph. stock gearing............... at least that's what the talk of the town is, rumored by the previous owner prior to selling to a buddy o mine. that's juss nucking futs. :rolleyes:

I like the stock gearing part, but what else is done to it?

You are an idiot. On PAVEMENT a COMPLETELY bone stock TRX250R would not hit the 75 mph mark, let alone 80-84! Haha!

An otherwise stock 250R with just reeds and a pipe WILL NOT be well into the mid 40s hp at the REAR WHEELS. A stock 250R with just a pipe will probably be more like mid 30s hp at the rear wheels.

[Honda 250r 001]

stock hp on a 250r is like 37. and yes wit pipe and reeds its possible to get mid-low 40's

[8686]

Oh boy. Here we go. Have you ever had your quad on a dyno? I have. You're probably thinking of hp numbers at the crank, not at the rear wheels. Until you become humbled by actually strapping your 250R on a dyno, don't talk about hp numbers.

[Honda 250r 001]

man its fuc kin common sence. How the fu ck can a quad with aftermarket parts on it make less horsepower than a stocker? HUH? answer that. Prove that sh it. got any pics? dyno sheets? toruqe numbers?

You're probably thinking about when the manufacturers release hp numbers for a quad. They always refer to the hp rating at the crank, not the rear wheels. And what do you mean "pics? dyno sheets?". Do you think I would lie about standing right there when my 250R was dynoed? Please...

[Honda 250r 001]

I dont see a reply with dyno sheets and pics!

[8686]

Patience, little one. I just got off the phone with my engine builder. He said just last week he had a stock 1987 TRX250R with a pipe on the dyno. Guess what it made? Not low to mid 40s! It made 37 hp AT THE REAR WHEELS. A piped stock 250R, just like you said. Dyno sheets are on the way.

[Honda 250r 001]

what pipe. esr trx 5? and v-force reeds? its possible man.

[8686]

My engine builder said bone stock 250R's make about 31-32 hp at the rear wheels. There isn't a pipe and reeds in the world that are going to gain 10-15 hp on a bone stock engine with no other mods at all. It's just not going to happen. The thing is, everyone thinks they are making way more hp than they actually are. One of the main reasons is they read too many magazines and look at what the manufacturers say their machines put out. The problem with that is those numbers are at the crank, not at the rear wheels. A bone stock 250R puts out about 37 hp, AT THE CRANK. You can factor in about a 15% drivetrain loss to give you a rear wheel hp number, which leaves you with 31-32 hp at the rear wheels.

It was a little longer than I remembered and a lot lower. Here was a bone stock 86 R with a pro circuit pipe and silencer, boyseen reeds. This motor even had the stock thick head gasket. The first pull was with a 158 main jet, we switched it to a 152 and picked up a couple.

Here is a bone stock Raptor 700, the little bit better run was with the air box lid removed.

Do yourself a favor and STOP trying to bypass the word filter. Keep it clean or just keep it to yourself!!:grr:

You just burned your only "get outta jail free" pass.

[factoryX]

The trx250r rexceived a less powerful motor! they wanted to make it a less of a danger for people to ride it! the water cooler three wheeler was more powerful than the 87-89 trx250r... so what you are telling me is that a blaster, with a pipe/carb/reed is more powerful than a trx250r motor with a pipe? Also, this is a chassis dyno, so you loose about 5-7hp, I am talking about hp at the crank...I agree that 80mph is a strech, but it goes over 70mph for sure...

[mcboomport]

Wait a minute. FactoryX, what are you talking about? You just said the complete opposite on the first page of this thread. Do you have any clue what your talking about, or are you seriously talking trash on this thread as well as two others i've seen you on!!??

"a stock 86 atc250r trike will hit 84-86mph stock, And I am saying that since the trx250r has the same motor but with more wieght, I'd say around 80-84mph is correct. the 250r trikes are nuts."

[factoryX]

lol, what I said is what I stand by, but what I am talking about now is that I disagree with people saying that these bikes barely make 32hp stock. okay, I have seen videos where these bikes have pulled 84mph and was told that they close if not 82-84mph stock, that is where I got my info for the the stock mph. The thread is about a trx250r vs. a raptor 700. I was simply pointing out that the 250r should be hanging in there with a stock 700r, but where is there a stock 700r?
The 1986 tecate 3 wheeler is pushing 40hp, okay, the 85-86 atc/trx250r was made to compete with it right? yes these bikes are fast and I think people do not give them enough credit.

[8686]

Horsepower numbers at the crank hardly mean squat. It's what you can lay down at the rear wheels that means anything. A monkey knows that. Hey factoryX, maybe you should stop talking for a while and maybe people will forget what an idiot you sound like. Try it.

[mcboomport]

I would go with Machwon and 8686 on this one....

it has a pipe, Rad valve, 38 a/s, cool head with race dome, 200 psi and a play port. it was also rumored to have a 300 b/b sleeve and a 4mm strock as well but i shot that down within 5 mins. of rolling it into the shop. :cool:
