125 hybrid

[250rider1]

anybody have pics of a hybrid with a 125 2 stroke out of a dirt bike?

[Tri-valleyracin]

in wat quad?

[Ripitupfilms]

y would any one do that

[ZeroLogic]

for racing


its been done but with a cr85 motor in a 300ex or 400ex frame i forget but i saw it and it was forsale

[Tri-valleyracin]

if u goin to do a hybrid like that do a cr250 or crf 250 motor in a 300ex or blaster maybe a 400 but that would have no point. dont forget the like a lot of $ cuse once u have a fast motor u need suspention and tires and every thing. but if u have the race parts already that would be sick.

i wouldnt put a cr250 in a quad frame it dosnt have a counter balance ( i think) so the vibration is insane and it can crack the frame

[Ripitupfilms]

Your ideas make no sense y would you put a cr250 engine in a 300ex or blaster frame... thats dumb thats y they made 250r's . and why put a big forstroke engine in a blaster or 300ex thats about pointless like he said put it in a 400frame . also do you think im dumb dude duhhh 85cc bike engines are but in all types of frames for racing

[Tri-valleyracin]

then y do they put yz250 motors in blaster frames ifs the have 250rs. its cuse u can and it wil hall a**. if u had the right set up for it it would prolly smoke a trx250r. and its the $ wise to not every one can aford a 250r or 450 so the got to work with wat they got and get small things here and there. think before u talk guy. for the vibration of the cr u put rubber stopers on the motor mounts to cut the vibration down. i have do the research for it belive me. but a counter balanced motor would be alot nicer but like i said work with wat u got. a 125 bike motor would suck in a quad. go 250 2 or 4 stroke. if it was in a 400ex frame it would be piont less cuse the 400ex motor could be made to blow the cr or yz motors in the smaller bikes away.

[Ripitupfilms]

(((( get off me ))) (((( think before u talk guy.))haha funny guy) haha nice coment ...ok let me see a quad(blaster) that has a 250yz engine in it and actually is faster than a 250r also just to let you know your gona have to work crap out of the clutch to get it to go fast enough to keep up

your statement doesnt make sense you said $ wise its cheaper but you also said the blaster has to be set up rite. which means to have the handling and suspension of a R your have to put money in it even stock to stock the shocks are way better.

[Tri-valleyracin]

yes the shocks on the 250r are kinda better but its cheaper to mod a blaster than a 250r. i have seen blaster beet 450's, 250r's and other quads. its only wat u can afore though. and how would u have to work the clutch to be faster. its just like wen they out the cr80 motosrs in a 300ex chassis they hall a** and they dont work the clutch. a yz250 motor i n a blaster would beas fast as a 250r or if not faster in a drag. on the track it realy depends on the rider. my friend has a 250r and its fast but it has its up and downs. i was say in 4 stroke before that wouldn't be as fast but on ther track and the right rider it would keep up to the 250r depending on wat mods it has. have u seen the price tags on the 250r's not eey on can buy one. i know i cant but on the other had i dont want one cuse there old. ya there fast but a yz250 motor in a blaster would keep up no prob.( if it was put in the frame right)

[Ripitupfilms]

another dumb coment y would you put a 250F engine in a blaster thats stupid as hell. thats even more money than buying a 250r. ANd again you dumb the 85cc powered quads the rider has to feather the clutch constantly. Also hmm a blaster beating a 450,,, yeah the 450 guy must have been garbage and the blaster rider must have been a very goood rider..IT ALL RIDER . come to D-6 where i know a kid with a stock blaster that will kill you in a mx race

[Tri-valleyracin]

o boy u know a kid wow i know alot of kids and a kid that raced a stock 300ex and won the pionts race. but this ant wat this post is about now is it. the 125 motor in a quad would suck a yz250r motor in a blaster would hall cuse it has more power and u can get them cheap. if u want four stroke get a regular 300 or some thing. a blaster motor can be fast but its not a racing motor like a yz or a cr. all u have to do is moint a radiator and custom motor mounts and rubber stoppers. it would be alot faster than a blaster. i think im goin to be do a hybrid like this , this winter. ill show how it turns out.

[Ripitupfilms]

iight throw me some pics

[kyleschonert]

I race in the Mid America arena Cross series. And the dominant bikes in the mini are 300ex and 400ex frames with CR85 motors in them. Nobody uses blaster frames. And if you put a yz250 motor in a blaster frame that thing would dog *** the whole time and would wheelie like crazy. If you wanna do that, get a 400ex frame with a YZ250F motor in it. 32HP stock, i think. And i race against a kid with that and no one can beat him. But dont use a blaster frame for a hybrid, get a 300 or 400.

[250rider1]

why would a 125 be so horrible? have u guys ridden one. they arent a lot slower than the 250 4 strokes and if you mod the 125 its easily just as fast.

[Tri-valleyracin]

the 250f have more h low end and mid than top and a 125 motor wouldnt have the guts to push a quad around i mean if u put in a light quad and mod the thing to hell and back then ya it would be fast but a250 would be much faster and prolly more up to the task of that job. my friend is thinking about putting a yz250 in his blaster so he has a chance aginst the 450s on the track and he dosnt have to $ to buy and mod a 450. im shure if iu put the time and $ into a 125 motor it would be fast but that time and $ in to a 250 4 or 2 stroke would be much more nicer to have than a 125.

just my .02

ok here ready for this

a cr 125 dirtbike weighs 197 lbs dry
a blaster weighs 324 lbs dry, a blaster is only a 200cc engine and stock it does about 53ish. A CR 125 is almost about half of the blaster engine so put that into a frame and it would do about 40-45MPH. Now if your gonna mod it like pipe and reeds it would get more accelartion and not to much top speed unless you change the sprockets. If you change the sprockets its gonna take alot of accelartion away and if your gonna race it thats now what you want.
Now say your gonna put a 12 year old kid on it and he weighs about 130lbs. so far you have about a 300lbs quad with a CR 125 engine in it plus the kid thats 130. so now your up to 430 lbs and thats alot of weight for a little engine so your not gonna be going to fast. even if you mod the hell out of it.
if you put it into a 300ex or 400ex frame it would go even slower because those frames weigh more than the blaster frame.

[rancid]

this ex blaster has a yz250 in it and it does vibrate a little when at idle, but when riding you dont even notice it.

[Tri-valleyracin]

lol know i want one
no ill rather get a 250f and put it in my 300. o ya best place to find parts is a bike salvage yard. im goin to one soon to find some parts.

hey rancid u got any more pics of like the motor and the mounts and stuff like that . that blaster is prolly the sickest blaster i have ever seen.

[rancid]

i will get more.

[BLRacing619]

ive seen many many many cr85 engines in blasters and they are even, ive only seen one 125 and it was also sick, and ive seen many many manp pictures of 250 engines in blasters and they rip

[Tri-valleyracin]

thanks that thing is sick

are you dumb? just because its a 125 doesnt mean anything. a yz80 smokes blasters. a 125 poos all over blasters. wow. i hate when people are like o its a 125 and a blaster is 200 so the blaster must be faster.

holy chit dude read before you flame me
i know a 125 can smoke a blaster and a 85 can too ive done it my self!
i was saying if you put a 125 engine into a blaster frame its gonna go slower because more weight

[Ripitupfilms]

weight dont matter riding ability . i weigh twice your weight and ill give it to you any day

i weigh 180 lol
and of course you would on a track because i hardy ever go on tracks but i dout that in the woods

[Ripitupfilms]

id beat you in the woods too i used to harescramble

[rancid]

so all i do is ride on trails that are rocky and smooth
i kept up with my friend when he was rideing his CR 250
and he didnt think i could either

[Ripitupfilms]

kewl come to rausch it give it to you on both i also cook for hershey park and make wonderful cookies

[kicker696]

i've heard of a couple guys putting the new crf250 motor inside 250r's and 400ex's, only seen one once, but it hauled ***. I built a 300ex with a crf250 motor in it that was pretty kickass, you would def. want to mod the suspension if you do either, cause let me tell you that thing is fast! We put a weld in 250r front end and a 250r rear on it for suspension

dude your an *******.............lots of people have done the conversion for a blaster with a yz250 motor, and actually im thinking of doing it myself, the vibrations arent that big of a deal if you arnt such a *****......and the rubber stoppers will help alot!! also this yz250 blaster would SMOKE an R there powervalved, for one, not 20 years old which makes it aalot more reliable. and it has alot more power than an R. dont get me wrong i love 250r i used to have. just leave the guy alone with what he wants to do maybe he wants to build a 125 powerd bike for his son to ride or somthing its not your deal so dont be such a dick

[Ripitupfilms]

woohhooo look here cool guy this post is old chill im just messing with him dam .. and i don't know were you live man put there are plenty of quads out there frame wise for just as much money to put the 250 engine in

scoooorree you got +1

[rancid]

i have one freind with a 265r with mild potring and a high rev pipe gets its *** kicked by my project 250 blaster and that motor is stock with a cpi inframe drag pipe and a open filter and it gets a good 4-6 bikes on it up the valley at little sahara, utah. i im not a 250r hater. and the vibration isnt bad either, it,s only noticable when it sits and idles.

[Ripitupfilms]

he must not know how to ride.

[rancid]

what it is, is the 250 blaster weighs less than the 250r and puts out more power, and its really noticable on the lowend. the bottom end is awsome on the yz250 motor.

yes it is!!!!!!!!!!!!!! that motor was meant to really move even stock...........

[rancid]

and its pretty cool when your rolling around the dunes on somthing that most people dont know what motor it is and most dont even know what quad it started out as. then when it kicks the crap out of the honda or some new bad 4 strokes thats even better.

[QuadJunkies]

well we are in the middle of a Blaster/YZ125 build and you can lighten the quad up to compensate for weight. I have heard of one other that has this conversion and was told it rips!

If you have kids who are too big for a mini, but still want to race Nationals in a shifter class with other kids ther own age then this is not such a bad idea. My Daughter weighs roughly 96 lbs. she is not a very big rider,just TALL...

Our build starts in one month!

if you put it into a 300ex or 400ex frame it would go even slower because those frames weigh more than the blaster frame.

That is not completly accuate.. The motors are NOT the same and CC's doesnt completly decide your power and performance.your comparing apples to Oranges. Im sorry, but I dont completly agree with this. I will be curious to find out what each motor weighs wil they are both pulled out. Im sure we will be learning ALOT on this build, should be interesting to say the least! LOL
