450R Swinger mount to a 85 R?

**Fox250R** · 02-02-2005, 04:18 PM

Hey i just got a 2005 TRX450R swinger from a friend who didnt want it anymore.I was wondering if you any of you guys would know if i could mount that to my 85 R? And what the weight differance would be..

My guess would be that without some modding the arm probly wont bolt up, being as the 450R is heavier and a fourstroke, the swingarm is probably beefier, but also heavier.

well you have the swinger right? and you have the 250R right? couldn't you just go and spend an hour to try it out?

i wouldnt do it...completely pointless...considering 250r swingarms last forever without 30 ft tabletops and constant racing...i think that it wouldnt be worth the custom shock valving, and/or custom linkage, and customizing the swingarm to do it...unless your pumping out monster HP, keep the 250r swinger...unless you have a lot of extra time and money.....

the stock 250R swingers suck they all crack back on the pinch bolt areas and the 450R swinger is cast alum i think so steel vs alum hmmmmm

the 450r swinger is also shorter, for some good, but most want a longer one.

i have never heard of a stock swinger cracking under normal use and proper maintenance, i have also never heard of a pinch bolt area cracking, this could only happen if you crank the ^@#$ out of the bolt, and if you do jumping of course it will break eventually....

I've heard of a lot of them breaking. I say if it fit, why not? I doubt it will fit but that's why he needs to try it.

I have one on my 86 r, i had to make a longer linkage bushing for where the link mounts to the bottom of the frame because the 450r link is narrower than the 250r, also you have to do the same to the top shock mount for the same reasons. Another thing is you will have to shave 1/8-1/4 inch off of the end of the steel tube where your airbox is ducted too. You can no longer use the duct due to the resivoir on the shock. I personally like it better than the 250 shock, its a little bit stiffer. Dont forget the 04-05 swingarms are shorter than a stock 250 by an inch or so. I also used the 450r axle it is a little bit wider than the 250r Sorry the brakes arent hooked up, had to rebuild the master and havent put it back on yet. It also is from a 450r

that looks nice but i would be laying on my butt!! i cant keep the front wheel down as is

**SYKO** · 01-09-2007, 11:38 PM

sweet jeff, I have been thinking of doing that to my 85 but set it up for flat tracking, did you use the 450r carier and axle or is that the 250r stuff?

**Billy Golightly** · 01-09-2007, 11:41 PM

This looks like a very beneficial mod...nice find and congrats on being probably one of the first people to actually do it

**jeffatc250r** · 01-10-2007, 12:01 AM

Yes thats a 450 carrier and axle. It didnt cost me much either, all from ebay the total price of everything was about $250. It is relatively simple
