450r swinger

[greenray]

:yup: anybody ever try to put a 450r swinger on an 85-86 250r?

[Black Sheep]

It's been done before but the 450R swingarms are shorter then the 250R swingarms.

If you look over on 3ww, There are 2 guys from australia that did it, Posts might be on here too. But basicaly its a bolt on almost. The 04/05 is shorter than stock 250r and 06+ is the same length.

No i have not done it Nor would I. But, I do have a brand new 06 TRX swingarm and I compared/measured it to my Original 86 ATC swingarm.

[3on3250-R]

I have measured both, and I'm quite sure the 06-08 TRX Is the same length as the 85-89 atc & trx (19.5"). Of course the 85 atc has a different diameter carrier. The stock 250R linkage will hit the stock 450 swingarm In the center If the suspension Is set up for full travel. The 400ex & 88-89 TRX Is the same length as a 04-05 TRX (18.5"). The 400ex shares the same carrier width as a 250r from 86-89, the 450R width Is slightly narrower but the diameter is the same. All of the linkage mounting locations are slightly different between the different machine's. Honda changed the linkage setup after going to the full cast aluminum swingarm, I'm sure because of the clearance Issue's

well that is were you are wrong.

the 85-86 ATC and 86/87 TRX are longer then the 88/89 TRX swingarm.

[3on3250-R]

Yes you are right, I typed that wrong. The 85-87 atc & trx are 19.5, and the 88-89 trx Is 19.5.

:ugh:

you are aware the 88/89 TRX swingarms are 1" shorter then the 85-87 TRX/ATC swingarms

[mitsumerlin]

Wow...I've never before reached such a tremendous headache in so short a time as I just did by reading this post.

85/86 ATC = 19.5 inches - steel
86/87 TRX = 19.5 inches - steel
88/89 TRX = 18.5 inches - aluminum

04/05 TRX = 18.5 inches - aluminum
06/08 TRX = 19.5 inches - aluminum

The stock 85/86 ATC or 86/87 TRX linkage can be used with mild modification, but will create a raised seat height. The 88/89 TRX dogbone can be used to lower that seat height due to it being a different length. Ideally, the DuraBlue lowering link should be used so that the ride height can be adjusted to fit the riders preference. The 250r shock itself will bolt in with little or no mods, but the 450r shock creates rather major mod issues if used.

All the the 0* TRX swingers will readily accept the 86/89 carriers in diameter, but they are not quite 3/16" narrower, requiring a very narrow spacer to be used if you run the 250r carrier and/or brake assembly.

Any other questions?

between this thread and that "other" one you seem to be hurting yourself. you should be more careful.

can you read a tape measure :doh: :rolleyes: ;)

Tell me you didn't just do that. YOU provided your own evidence to support ME and make yourself look stupid. Granted, my 20/15 vision is a little tired right now, but I'd say most will agree with me that 19.5" is dead center in the middle of that carrier housing.

[Black Sheep]

Obviously you've mastered the art of manipulation through misguidance.

the fact that you measure a swingarm from LEADING EDGE to center of carrier shows you have no clue how to properly determine swingarm length.

did you consider that the ALUMINUM swingarms have more material surrounding the pivot area. thus the thicker material will throw off a measurement.

if there is aprox 1/2" MORE material IN front of the pivot it will give you a misleading measurement to the center of the carrier thus fooling you into believing they are the same.

try measuring from CENTER of pivot to CENTER of carrier. you'll find your lost 1/2"

Did you even read or consider the link/thread from the first guy who actually did this swap? even he states the 450R swingarm is shorter.

look at his pic and take measurements for yourself...its aprox 1/2" shorter.


finally if you think your 20/15 vision impresses me think again i've got 20/5 :thumbsup:


NOW, i have some questions for YOU. did you really just come over here to discuss things or start crap? i can't but wonder why two post of yours, out of 7 or 8 in 4 yrs are directed at me! tell me something your from OHIO. any chance you'll be at smith rd on labor day?

[NOS_350X]

Bill in your picture with the tape is about the worst way to measure there is and you know it, All you really have to base off of is the axle, which moves forwards and backwards, 1" total

Take the 2 swingarms in the pivot area take the collar and put it in both swingarms side by side, Then look in side the carier area to see which is farther forward.

because IMO the trx swinger looks like its siting farther forward on top of the atc.


Yes i did read the austraila post, and he says 3 or 4 cm shorter, it dosent look to be any more than 1/4" to me.

yes i know i was messing with him :lmao:

1/4" or aprox 1/2" (what i said) so it's more like 3/8" lol

[NOS_350X]

Ya i thought it was kinda ironic, You say, dont measure by hooking it, right before that you hooked it for the pic. :thumbsup:

ill settle for 3/8's :doh: Next question, what rider will truely notice a diffrence.
I meen you dont notice handling diffrences after a chain streches, :chuckle:

I do get teh point, Yes it is shorter, lets make that known, BUT is it noticeable?

[mitsumerlin]

I love your little colored lines BS. Makes me feel like I'm back in kindygarden.

And yes, with a little luck, I will be attending the Labor Day Smith Road race. Which I have done several times now. How about you?

Nick, that all depends on the rider.

I personally use sidewinder chains that don't stretch so the adjustment is irrelevant to me.

is it noticeable? i can notice if my handlebars are 1mm out of adjustment. i can tell when my foot pegs get bent down a 1/8". there is a big difference in handling between the 85 R seat and the 86 R seat. so for me 3/8" is a big difference.

However not only is the 450R swingarm Shorter, it requires messing with the linkage, and is made from aluminum. Aluminum swingarms are prone to cracking under hard use that is why the aftermarket don't make them anymore. if you ever owned a Cal-Fab they cracked all the time.

additionally the hot race set up for 250R's was/is to lengthen then anywhere from 1-2"

personally if i was still messing with vintage 3wheelers i would buy or make a chromoly swingarm specifically for the 250R

So your stuck whe wherever it lies??

I do agree, Yes it is going the wrong direction, the linkage will affect things alot more than the 3/8" shorter swinger will
Also that on almost any case on an atc you want to go longer. I do still feel that the 450 swinger is a nice little setup for a replacemnt 250r. Also 450 aftermarket swingarms are EXTREMELY avaliable. I happen to have a -4 for sale.
