Well here is my latest mod to my x4, A $2.00 KX85 caliper off of ebay.
A little custom fab on the mount and a new set of pads and they grip like a vice.
Haven't gotten to ride it yet but it definately feels like the dual pistons are going to make a big difference.

You need more front brake? Mine is crazy strong stock,almost better than my CRF.

Pretty sick bikes aren't they.I was pretty shocked the first time I rode mine.It is not a pit bike,it is a 3/4 size cr/kx/rm/yz 125.

johnr6 · 01-21-2008, 05:54 PM

how much fabbing did you have to do to make it fit ?

orracle · 01-21-2008, 05:57 PM

No, I didn't "need" more front brake, its just nice to have. As for the fabbing, I had to weld up the stock 85 mounting holes. Line up the caliper on the forks mark and drill the new holes, and then tap them for the stock hardware. Doesn't take long if you have the equipment.

Now that is a GOOD idea. Can't wait to hear how it works out.

Yea I couldn't pass it up, I didn't even know if it would work but I figured it wasn't much of a loss if it didn't.

magiksc · 01-21-2008, 06:20 PM

That is really good mod.

10-32 · 01-21-2008, 06:21 PM

good job, i have been wanting to upgrade the calipers on my x4 since i got it. The brakes on the x4 are the weakest link and im gonna do the same as you.

Thanks!

carnutvic · 01-21-2008, 06:23 PM

What motor are you running? I have the 08 150 and am having jetting issues.The pilot is too lean,it is not marked.

orracle · 01-21-2008, 06:24 PM

I have the older gpx 124, its apart right now waiting for the stroker crank to make it a 157.

slater · 01-21-2008, 06:25 PM

Well you beat me to it but there is a front brake mod/ bracket coming in the next few weeks using a name brand big bike complete front brake system.

Pictures and a link to the bracket will come soon.

oo interesting, from the sound of it there should be a good market for it.

slater · 01-21-2008, 06:34 PM

My stock front brakes are Ok but it also takes alot of pull on the lever to really get the bike to stop. It seems as if you either you grap a handle full of stock brakes or you are barely using them.

Wandell · 01-21-2008, 06:48 PM

Nice!

slater · 01-21-2008, 06:52 PM

probably about 2 weeks if not sooner.

10-32 · 01-21-2008, 06:54 PM

what caliper does your kit use

slater · 01-21-2008, 07:12 PM

rather not say at this time, but it does come from a name brand big bike.

Kurlon · 01-31-2008, 08:49 PM

How is the pad contact area with your setup? Looks like you might be needing a slightly larger rotor with the caliper mounted where it is?
