450R Swinger mount to a 85 R?

[Fox250R]

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..

[Tri-Z Pilot]

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.

[BigGreenMachine]

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?

[Curtis-Tecate3]

^^^^What he said.......
My thoughts exactly.

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.....

[Xowner]

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

[deathman53]

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

[hrc85250r]

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.

[hrc85250r]

my stocker is 20 yrs old...no breaks yet, and it has been down 15 ft drops....and jumped........lol,...

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]

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]

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

[jeffatc250r]

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

[ProCarbine2k1]

very nice... i think theres a lot of stuff from the newer machines that could go on our trikes with minimal modification... it just takes one person to give it a shot... good job!!

[torker]

Wowww.
Does this thing actually lings up???
More pics please!!!!!!
Do you know the difference in weight?
Imagine, 450R rear susoension and KTM upside down fron susp. NUFF SAID!!!

I know it takes a lot more than just putting the parts, tunning and setting, but man...This is bringing the dinosaurs back to life!!!!!!!

THAT ROCKSSSSSSS.
TORKER.

[jeffatc250r]

Ive had this on for 5 months or so and prob have over 50 hrs on it and nothing has given me a problem, chain lines up perfect, everything works mint!! Ill post more pics tomm, what exactly do you want to see??

[jeffatc250r]

Oh and the weight is about the same i think

[Billy Golightly]

So the 250R and 450R sprockets take the same pattern? How about brake disc and such. Do the axles interchange? Damn I might want to get rid of my Z and go all modern suspension 250R now :drool:

[jeffatc250r]

I used a new 250r sprocket i had kicking around, the sprocket allen bolts are bigger on the 450 i had to get them at the honda shop for $30. I think the brake disc and hub are the same as the 250r but i havent tried this yet so not 100 percent sure, i have a 450 disc and hub. I think the axles interchange too. If you use the 450 axle you have to get 450 hubs as the 250r wheel hubs arent the same size.

[torker]

Would love to see the top part of the shock and the swingarm/frame mounting point.
This just keep getting better!!!!!!

TORKER.

[Fox250R]

Thanks for the help guys , but i traded the swinger for a gun like umm,, over a year ago lol...Jesus this thread is really 2 years old? Holycrap time flys!

[petesatc]

the 06/07 450r have a 1" longer swinger .......so if you want a standard 250r swinger length go for the 06/07

[jeffatc250r]

Yes thats right the 06 and 07 is longer, just be sure you get the 06-07 shock linkage though

[X2guy]

Awesome...I saw one on ebay a week or so ago and wondered if it could be done.
Will the 250R linkage and shock work or do you have to use the 450R stuff.

[Jason Hall]

jeffatc250r, Great Idea, that really looks sweet. I think a 06-07 swinger would be cool cause It's the same lenght as a stock R. It really shows how well honda built there stuff way back when. They really have'nt change that much In over 20 years. I wonder If the axle carrier has the same outside diameter. I know alot of people used to put 250R brake calipars & rotors on 400ex for better groung clearance & longer lasting brake pads. If the 450 stuff Is close to the same the Interchanging will carry on even longer.

[jeffatc250r]

x2 guy You have to use the 450 shock and link, the 250 will not work at all. you can use the 250r brake caliper and holder

This was done on a quad not to long ago, I remembered reading about it so I went and found it on exriders. I don't know what the 450 swinger weighs but I know I saved at least 10 pounds when I did the switch on my trx from steel to aluminum.

Wow, here's a thread a I forgot about. What's funny is after I posted in here 452x and I ended up installing one of these 450R swingers in a 350x!

Looks good jeffatc25r, good job!

Why won't it work? The post on exriders sounds like they did use the 250R link.
Also does anyone know if a 250R carrier will work in the 450 swinger?
I'm doing this mod for sure.
