More 450R parts on an ATC discussion THREAD..... **SWINGARM UPDATE**

[fire1]

do you know if the 250r sprocket will bolt to the 450r axle just bought 250r sprocket and was hoping not to have to buy another thanks for info hope you dont mind if i have a few more questions.

[SYKO]

yes it will thats what is on mine 15/28

[willrideanythin]

Will a 350X swing bolt on and line up with any dirt bike swingers? DB swingers seem narrower by nature. Might be cool to swap it the other way too. Just thinking out loud.

what did you do to have to get it to work?

Very nice build fire1. You have a beautiful R with some very nice custom additions. Looks like you used the oem 250R shock. I've heard this is difficult for some reason? Can you elaborate on the rear end conversion. I'm sure there are many people that would love the late model 450R rear. And a step by step process if possible.

Someone used a yfz450 front caliper on the back of their 250r, I wanna say it was , but am not quite sure, I will try searching it.

Mosh is talking to another member about making all the required spacers and bushings need to drop the 450R swinger directly to a watercooled R trike or quad.
This way all you have to do is get the swinger and 450 linkage and buy a affordable bushing and spacer kit and bolt it on.
I am pretty sure he will post it up once it is done.
The 450 stock swingarms are selling so cheap it is rediculous.

[fire1]

theres no spacers or bushing required it drops right in width wise and all you have to do is cut the inside bushing on each side for the r rear motor mount to fit took all of 10 min this is really easy.i used a durablue adjustable dog bone link to get correct ride height.i bought the hole rear setup off ebay bearing carrier ,axle ,rear brakes complete,axle nuts ,wheel hubs and sprocket with bolts for 210.00.i used the stock shock because i had just had it rebuilt and the 450r shock is to stiff and you can not use stock air box.i get full travel using the adjustable dog bone link.

ALSO STOCK SWING BOLT WORKS

beautiful build. great job Fire. Thanks for sharing!

[Mosh]

Thanks for the info.
From what I have been told, if you use the 450r linkage with the R shock, The bolts or bushings were a little sloppy and did not fit correct. Something about the bolt hole sizing form the R shock and 450 Linkage being different? Just what I was told. Or something about the shock bolt hitting the swinger before you get full travel?
Also, the deal I am doing is using the 250R axle and brakes and rotor,and that requires a bushing to make the caliper bracket fit correctly, if you want to save money and run your old R axle and brakes, instead of buying the hole rear end off a 450r.

The way I am doing it I was just trying to use the 450R swinger and linkage,and existing R parts.

My trial will be using a 2004 450R swinger on a 86 TRX to shorten it up to near the 88-89 length. Maybe the 2004 450R linkage is different requiring some modified spacers???

I have seen just the 450R swinger and linkage go for around 30 bucks on ebay plus shiping.
Add the projected 30 bucks for the bushing kit to make it work and the whole deal would only cost 60-75 bucks. Using the exisiting R parts.
