well that line is whatever was on the bike probably newer r but other then the length any line will work

i dont see why you cant just use the caliper.

it;s a stainless line for a trx250r. the trx's and yz's have the same ends at the caliper. SWIGINS my brother the 350RX is mostly mine.

i have just the caliper on my 86 trx250r and it works great. you just have to egg out the holes a little like he described

since you have a 85 atc you'll have to get a 86 caliper bracket that slides over the carrier. plus weld a stud on your swingarm

the 86-89 atc/trx's dont have the linkage they have the stud sticking out of the swingarm. it keeps the caliper in place like the linkage piece on 85 250r's

**DeePa** · 04-09-2007, 07:28 PM

do you have to weld the stud?

Mike

**jason85atc250r** · 04-09-2007, 07:36 PM

yes you will have to weld it on. look on a site like bikebandit.com at the parts pictures and you'll see what it looks like.

**DeePa** · 04-09-2007, 07:43 PM

well then what else do i need for this mod

the linkage off of a 86 r? Will my 85r stuff work?

DO you use the YZ mounting bracket for the caliper?

Mike

**jason85atc250r** · 04-09-2007, 07:48 PM

you'll need the caliper accentric piece that slides over the axle housing. and weld the stud like i explained.

you'll need the yz caliper with the mounting bracket. just egg out the holes and stuff like my brother explained

i'll pm you my number if you want to ask in person

OK...

I have teh caliper and mounting bracket from teh YZ

I am buying a 86 caliper stay (the one with teh ovaled out section, unlike the 85.)

I dont get it, does that stud go on the swinger adn the egg shape goes over it? Can you get a picture of it?

Mike

Here are some pics for ya. The best I can do without taking things apart

This one shows how the bracket goes on the swingarm.
You can see that there is a pin with a nylon button on it.
This what keeps the caliper from turning, like the linkage bar on the 85's
On the bearing carrier, there is a clip that keeps the bracket in place.
I don't know whether or not the 85 carrier had the groove in it for a clip.

This one shows the caliper mounted on the bracket.
You need to egg the holes out on the 250R mounting bracket just a little.
The holes on the YZ bracket are just a hair off.
Hopefully these help.
