Hmm...

My old '87 250r had an FMF Fatty Pipe, Duncan Fatboy 2 Silencer, CT Reed Cage, Boyesen Reeds, Reed Spacer, .40 over Pro X, UNI Filter, and cr250 head gasket. It flew!

It was definatly faster then my old cammed/piped/ported/polished/filtered/jetted 400ex.
I haven't gotten the 400 back from its transformation to a 426, but I'd be willing to bet it would have given the old R a run for its money in a drag, if not beat it.

250rs are quick, don't get me wrong, but they aren't the fastest. There's plenty of atvs that could stomp one.

A stock 250R has ~ 28-32 RWHP
How much does a stock 400EX have?

 

Stock for Stock a 250R will smoke a 400ex. and i am willing to say that it could take all the 400's 450's 660 700 (not the 350 shee) 300 all them

 

I think it's about that. Except I think it's at least 30 but I'm unsure if it's at the engine.

 

i think stock for stock you may be right but i would watch out for thoes 450's!!!!! they are pretty quick off the line

 

If you are going stock to stock, the 250r will NOT take a 450. I dragged my brothers LT250R('87) and embarrassed him bad enough he bought a YFZ also. My Yamaha was stock, he had a Pipe/filter and a freshly resleeved cylinder. We did switch riders with similar results, repeated a bunch of times.

 

And I am willing to say your wrong because I have owned a modded one and I didn't beat a stock raptor in a drag.

250r are dieing out 4 stokes are just chetching up yea they were good but y have one u need to fix and work on these days when u can have a 4 stoke and just put some quick stuff on and have a warentee and more reliablity? its many the rider if they are about tie.

ill wreck u on any terrain on my 4 stroke with a rider jsut as good as me on a 250r thats for sure!

 

Thats a pretty big statement to make.
The 250R is a pretty good ATV in MANY differen't situations!

Sand comes to mind as one place where you might have trouble keeping up with one.
I've seen the Canondales out at St. Anthony, and yes they are fast powerful ATVs, but I think there are more than a few 250Rs you'd have a problem "wrecking" [img]i/expressions/face-icon-small-wink.gif[/img]

 

before i got rid of my 250 it was very reliable. i rode it for 2 1/2 years before i repalced the rings in it. its all a matter of keeping it jetted right and keeping the gas/oil mix correct.
