How to make a bike brake like a ktm?

You need a Braking 270mm Batfly Oversized Rotor Kit. I've heard nothing but good things about this setup.

Like I don't understand what's different about the ktm brakes that makes them sooo much better... someone said something about them having three pistons instead of two or something?

Brembo calipers are arguably better quality than the Nissin calipers (tighter tolerances, better manufacturing, etc...). They still only have two pistons like the Nissin calipers. KTMs also come with braided steel lines, which is a major difference from the Jap bikes.

At one point, Reed (I think it was Reed) was running a one-off front brake caliper that was custom machined and the tolerances were so tight it didn't require seals. I don't remember which bike this was. Probably cost more than a brand new bike.

For the KX, get a braided steel line first. It will make a notable difference. I jumped to a braided steel line AND oversized rotor and it was way too much front brake for me.

It is the Factory Hondas that use the works machined front caliper, they are so trick! compare it to the caliper that RV uses below (same company i believe)

So here's my story on how I got a Brembo front caliper off a KTM to mount to my YZ250 2 stroke.

Bike: 2005 YZ 250 w/ SSS forks from a 2009 YZ250f.

I bought a used 2007 KTM 250SX-F front brake setup for $142 shipped off eBay. My buddy tried same setup on his 2013 RMZ 450 which is what gave me the idea.

I took the mounting bracket off the brembo caliper and tried to see how well it lined up with the stock holes on the bottom of my forks. It turns out the stock top hole and this other unused hole on the brembo bracket lined up 100% perfectly with the stock fork holes. See picture below. Where my thumb is on the bottom is the new hole you will be using to mount this caliper. You will notice the new hole does not have a raise edge like the top so the caliper wont line up even, the use of spacers are required to make this work anyway so using 1 more spacer on the bottom did the job.

Here it is mounted to the stock holes on my SSS forks.


Next comes the issue of once you put that caliper on the bracket and try and line up the bolt holes again you'll notice it does not work because the edge of the caliper assembly is now overlapping the mounting hole. See picture below.


Here is where you need to decide if you want to grind some material off your fork bracket and the edge of the caliper. If not.. your best option is to just use the master cylinder and steel braided line and buy an oversized rotor and call it a day. I did not mind. "In My Opinion" there is plenty of material to work with to where saftey, rigidity, etc.. is maintained. I am no engineer nor do I claim to be. Pics below of how much material I ground off. I did make the mistake of grinding too much material on the caliper which was irreversible. I did have to buy a second 2007 250sxf used caliper only assembly this time for $65 and try again with grinding more off the fork side and less off the caliper side.


Here is the fitment still a little too tight as the slide pin is not centered. You want this to be centered so you can put the stock rubber grommet back in to resist vibration and movement.


Here is the finished product. I ended up needing to take more off the fork side and less off the caliper side on this second caliper. I have about 2mm of gap between the fork bracket and calpier now which is plenty as these two peices are one with each other the only movement needed is side to side as the pads wear down and the caliper needs to slide one way or another.


Here is a couple pictures of the vertical alignment. The use of M8 metric washers was needed in order to achieve the centering of the rotor disc in the caliper just as it would be stock.



Here is a view of the pad coverage. The coverage is at an angle somewhat, but It covers fully and after testing the bike I definitely have better braking all around.


Here is a picture of the spacers I used. 2 stainless M8 washers on top. 3 on bottom.



Here is a picture of the spacers I used on the bottom side mount. I used 3 here in order to make up for this bottom mounting hole not having that raised edge. The thickness of that raised edge was exactly the thickness of this washer.





Heres a few pics of the actual bike. Hope this post helped someone.
