i was saying you can by this yz caliper and do the swap. saves you some money since you only have to buy the caliper instaed of all the 450r stuff. the yz caliper is dual piston.

so I can put this yz caliper in place of the 450R caliper? becouse now I will be going to a complete 450r setup (swinger,carrier,axle)

you put the yz caliper in place of your factory 250r one. just reuse all the rest. the 250r rotor is smaller which is better anyway.

just trying to save a fellow 3ww member some coin

ok what? the 250R disc will work on the 450R hub?

**jason85atc250r** · 10-07-2007, 06:23 PM

i meant just keep all your 250r stuff and just buy a yz caliper to replace your stock 250r one. dont bother with the 450r stuff you wont need to buy any of it.

**SYKO** · 10-07-2007, 06:32 PM

ohhh ok, man I was realy starting to get confused! didnt know what fit what and how!

**jason85atc250r** · 10-07-2007, 06:37 PM

i know you can put the 450r swingarm and axle housing and all the 250r brake stuff will fit rite on.

alot of guys posted on atvriders.com about putting 450r brake stuff onto the trx250r axle and housing and it bolts rite up.

**SYKO** · 10-07-2007, 08:32 PM

so the 86 250R brake stay will go on a 450R carrier? man... this shyts getting comfusing!

**jason85atc250r** · 10-07-2007, 09:17 PM

yes it will and you can use your rotor and hub ad the yz dual piston caliper them

**SYKO** · 10-07-2007, 09:18 PM

so I can officialy take the 450R brake stay and caliper off my want list now huh? and the disc hub will work on a 450R axle as well?

**jason85atc250r** · 10-07-2007, 09:30 PM

yes it will. my buddy used my trx250r axle with all his 450r stuff while his lonestar was getting warretied

Bump for wanting to know a specific guaranteed to fit year yz front caliper.

**Jason125m** · 11-10-2012, 04:06 PM

Just installed a 2002 yz125 front caliper on the rear of my 86 R, had to do a little filing, other than that it is a direct swap.
