Has anyone seen or heard of someone using the 250r ninja or 250 honda cbr street bike motors in a quad

 

Did honda even make a 250 cbr? I dont think they did. I think the smallest cbr was a 400.
As for the 250 ninja motor, i've never seen it done and that's probably because it's not that fast of a motor to begin with. Usually if somebody is going to go through all of the trouble of putting a motorcycle motor in a quad they get something bigger like the 500 cc ninja motor. Now that conversion has been done at least a few times before.

 

don't mojave's have the ninja 250 engine in them?

 

your right i dont think honda did make a 250, oh well thanks for replying

 

No mojave's don't have ninja 250r motors in them.THe ninja 250 motor is a twin I am pretty sure.They are quick for a 250 though I rode on and it rode a wheelie in to 4th!It scared me.The dudes with hayabusa's and cbr929's are crazy!

 

What I think would be a killer set up is a RC51 motor (Vtwin Honda crotch rocket) in a 400EX frame. It would be a narrow motor and scream.

 

i knopw some1 that has a 250 ninja. i'll go take a look at it tommarow maybe. i think it is one cylender but i'm probably wrong. and yoru right they are quick for a 250. i know some1 that had a gsx 1000 and he would ride wheelies down my street going really really fast.

 

The ninja 250 is a parallel twin(8 valve).

The kawi website claims that the ninja250 weighs in at 300 pounds...does not say anything about horsepower. It might be a bit underpowered for a quad.
I agree with what was posted above....most people would not go through the hassle of fabricating mounts and fittings to make such a small motorcycle engine work in a quad.... The 500 might be a better option.

 

A 250 ninja has around 27 horsepower and 16 lb ft of torque. Basically it would get spanked by a 400ex. Also, I would like to see someone ride a 4th gear wheelie on a 250 ninja

 

Honda did make a 250 but it wasn't a cbr,I can't remember the model but it looked like a small VFR
