250R Swingarms

[OldSchoolin86]

EDIT: Does anyone know if a swingarm from a 400EX or a 450R will work on an ATC250R? I'm tossing some ideas around about aluminum swingarms as well and if I can do it and have it lengthened by 4" or 5", it may be a project for next year.

The 400ex and 450r swingarms are all cast aluminum. I won't say it's impossible but you couldn't get me to ride on stretched cast aluminum swinger. The 88-89R swinger tho just has cast ends, the middle would be a lot easier to stretch but you'd be pushing your cast linkage mount back too.

Just as 3legged said the 400ex swinger will bolt into the frame but I couldn't tell you about if the R linkage would mount to it. I know the 400ex shock and linkage didn't want to fit on the R frame.

That's good info on the 400 and 450 OS86, thanks. The 88-89 swingarm does look like it would be tough to stretch becasue the place to cut it right in front of the carrier is pretty solid looking with no exposed tube. Are you saying that it's cast at that point?

You know you might be able to chop the 88-89 right behind the housing but I don't know what you'll find when you open it. I'd guess it's mostly hollow there and the bonus is that the outside members are not cast and they run all the way to the housing. To be perfectly honest tho, I don't know jack about extentions but what I know about metals says that if you're gonna do it, that would be the one to try on.

That's exactly what I was thinking and one I've been watching. I'd cut it where your green arrow is and go from there. But, since it's already 1" shorter than my swingarm, I'd need to add 5" minimum to get to where I want to be. I'm sure it could be beefed up enough to be strong, but it could be dicey.

LOL!!!!!!!!!!!!! YOU TWO GUYS STILL CRACK ME UP!!!!!! i remember the days of desert union when nobody knew you were brothers!!! wonder what ever happened to paul???? keep it up

Yep, the good old days of Desert Union were something else. All 250R's all the time! There were some seriously pissed off people there that didn't catch on to BS that was going on, but Red and I didn't start it, it was all Mucho Mas's fault, hhhhhhhhhheeeeeeeeeeee dint knnnowwwwww waht kinded uf havocs heeeeeeeeeee wus cuasing, it was just his language barrier and stickey keyboard. I heard he was deported so I don't think he'll ever show up here! As for Paul, who knows? Wasn't he one of Mymint87's buds?

LOL. I'm with you boys. Desert Union was a great site. Shame it isn't still up. At the height of the Sandman Vs Redrider post, I'd logon every day just to see the lastest installment. It just got better and better. It was hilarious to watch everyone begin to react to your guys' posts, not knowing that you were brothers.

Long live the good old days

Cheers,

Back to the subject at hand...Kasey, what swinger set up do you have on your 500? Is it a custom aftermarket unit or a reworked/lengthened R swingarm?

i extended a stock 85 arm to 6+ i really like the way it handles ... still jumps great.. i also think the swingarm is stronger than some of the aftermarket ones i have seen too.
