im 99.9% sure that the bottoms of marz. shivers are the same as the bottoms of ktm65 forks. so that means that the ktm front brake caliper will mount strait up to my shivers.

and my formula brakes suck nuts, so i was thinkin about gettin a ktm65 caliper, line, and master cylinder from my good buddy ebay, but he didnt have any...

any1 on here have a set?

well ive looked at both and it looks like both forks are shaped the same. i know that marz. make ktm forks for their little bikes (probly the big bikes too, but not sure on that). so, yeah i think they are the same.

the formulas and the hayes brakes use billet adapter brackets. if i were to get the ktm brakes, they would mount to the black brackets on the fork bottoms without an adapter bracket. at least thats what im thinkin

To put the ktm brakes on the klx lugs will not work . You need the ktm lugs to make it work.


I don't think that is what he is asking.



He is asking if the aftermarket Marzocchi bottom bracket is the same as the KTM bottom bracket.



Pax, you will probly know. But I think it is different.



Also, AFAIK, you cannot buy just the KTM bottom bracket. KTM does not sell it that way. There is no seperate part # for it in the fische.

I put a ktm 65/85 front brake setup on my 50 shivers. I had to make a bracket similar to the one that the formula uses, and do some cutting on the caliper. I used the 200mm galfer wave rotor that BBR sells. It is possible and VERY nice when it is done.

Handlebar Aluminium Ø 22 mm (0.87")

Front suspension Marzocchi USD Ø 35 mm (1.38")

Rear suspension WP mono shock

Suspension travel front / rear 220 / 270 mm (8.66 / 10.63")

Front brake Disc brake Ø 200 mm (7.87")

Rear brake Disc brake Ø 160 mm (6.3")

i swear they look identical


If you have access to both types. just measure them....



I know the wheel hubs are different. You will have to source a KTM wheel. That will place the correct diameter disc in the correct position to fit the caliper. ANd you may possibly need a KTM axle and wheel spacers. If you go this route... make SURE the wheel comes WITH the spacers. The KTM ones are on backorder and are a bitch to figure out. Also, there is an inner hub spacer that is not available from the factory. Make sure the wheel has that as well.



Someone said the "Zokes" brake uses an adapter bracket. Maybe the fork bottom actually is the same....



Vendors would not like that secret to be well known....

my formulas use an adapter like gary sells for the kx brakes. so do the hayes i think. and the formula rotors 200mm just like the ktms...

i was thinkin i could use the marz. hub, formula rotor and ktm everything else

jRob409...



That is nice.



if the Galfer disc is 200 mm & the KLM disc is 200 mm, why did the caliper need to be offset outward at the bottom bolt? Seems like the disc would not mate correctly with the pads that way? Or did it just make fabbing the bracket easier?



The other option would be a spacer between the disc and the hub. That may be even easier....

The legs on the forks may not be the same length. I dont remeber for sure. The rotor is all the way at the outer edge of the pads. I had to machine down the mounting pads on the caliper almost half of what they were orig. to get it to slide between the fork lug and the caliper. I have been running that system for approx 6 mons and havent had any problems.

NOTE: this caliper isn't a floating caliper right?? If so that means that the position of the caliper has to be aligned perfectly centered in between the rotor so that both sides of the caliper, the pistons will meet at the rotor at the same time, which means you will have to machine a bracket so that the alignment is perfect or use shims which will be a PITA.



So Why is it that you can buy the BBR front brake kit (With a bomb Galfer rotor) for $289.95 (I think that is the price) or a KX65 set up for roughly the same or cheaper if you get the parts off of ebay,,,,why is this not the way to go, rather you would want to pound your head into the wall trying to get something else to work when the KX65 and the BBR brakes work awesome????

the ktm brakes should mount strait up (with no head punding).

jRob409 has the ktm65 brakes on 50 zokes. not 110 zokes. idk if they are different. so if they mount strait up to 110 zokes, you could buy the caliper, line, and master cylinder and not haveto buy any adapter brackets...



as for the cost of the ktm brakes; it all depends on where you get them from. i think MotoSport Outlet charges like 300 and something for a caliper, line, and master cylinder, but if you could find some on ebay, they'd be cheaper.

You are missing the picture they aren't a floating caliper

You are correct in the fact that it isnt a floating caliper, it is a 4 piston caliper. So the alignment doesnt have to be exactly perfect. Yes, I could have bought a BBR setup, but I called them and discussed it with them and they didnt recomend it for dirt applications because the caliper hangs down quite aways and would get caught in ruts, rocks, ect.

$289.95, I am pretty close to being the same price for what I have and it isnt the same thing everyone else has.

507 brett obviously wants to try the ktm brakes, and I give him props for wanting to try something diff. I sure am glad that everyone didnt give you a bunch of chit for trying something diff when you started machineing your brackets to use kx65 stuff on the zochs. Man, if somebody hadnt went down the road less traveled we wouldnt be riding 20hp klxs and pushing 190cc out of them.

The CRF50 Marzocchi's are the same Caliper mount pattern as the KLX110 so you will have to create an adapter bracket, so there will be a little head pounding! LOL J/K

Actually it does have to be centered and the reason is that if one side is off then when the piston on one side is closer to the rotor it will push the rotor(bend it over) until the other piston hits the rotor (NOTE: THat isn't a good thing LOL) because through time the rotor will become bent or warped!

This brake set up is going onto a KLX110 fork isn't it? That is what the BBR brake kit is for is the KLX110 forks for Dirt Applications, so I don't understand why they would say that it wouldn't be good for dirt? If you ever get a chance to look at the 160mm Rotor that the Marzocchi forks run with the 50's and look at the Formula Caliper and how low the Caliper hangs down and you would probably never worry about where the BBR caliper hangs because Marzocchi has never had one of those formula calipers ever brake off from hanging down so low.

That is cool to be different!

I had the KX65 brakes on my KLX110 over 2 years ago with a one off (w/manual mill) machined out bracket (That wasn't pretty, LOL) because the Formula brakes didn't work and I was tired of going to the track and not having any brakes. Then people started asking me to make them the caliper mount so often that later I milled out a CNC billet part to adapt the KX65 front brakes onto the KLX110 marzocchi forks,,,,, and this was before BBR had there Oversized brakes! If you look in a post about 2 years ago in August I mentioned these caliper adapters when we were making the rear mounts. So it wasn't because I wanted to be different as much as there wasn't anything else that worked, and once the KX65 brakes were put on the bike there hasn't been any problems with braking anymore!



NOTE: If someone had an adapter bracket to run the KX65 front brakes on the Marzocchi forks I would of Paid $500.00 for the brake because I spent $200 for the Manually milled brake adapter that I had my machinist do for my bike! (One off stuff is a son of a b in pricing!)
