As many of you know, the brakes on the 2000s RMs weren't top of the line stoppers. My 03 is no exception and is unacceptable to me so I bought a 2004 line to update it...

....however, my 03 KTM125 had a viscious front brake that required nearly no thought or pressure to stop all forward motion.

So I wondered if the KTM Brembo parts can be fitted to the RM? Has anyone used this set up?

I doubt it. The mounting brackets on the Brembo will not match up with the Nissan on the Suzuki.

The only way I think you could do this would be to have a custom fork lug made that has the proper mounting ears for the Brembo. Probably way to much $$$$ for what it's worth.

You should put an oversize rotor on the front, SS braided lines front and back, rebuild both master cylinders and then install a set of very high-bite MX/SX pads. You would be surprised how much better you can make the stock components with these upgrades.

I'm sure new pads would help a bit...I've seen the set you're describing, they're rated pretty high. I'll shop around for the parts you've suggested.


BTW, do they still cruise up there? I grew up in Aledo and we used to go to G'burg on Saturday nights. There used to be a pro street Monza, a pro street Impalla and a legal Funnycar roaming around back then.

Thanks for the tips.

when I was at llynns in 2012 I lined up next to Dr.D, on his yz 450 was a brembo front master clylinder, that was the last time I saw him!

I had an 03 RM 250. I replaced the front line with a stainless steel one. Still was not great.

I would try a different master cylinder or oversized front rotor.

I have a 03 RM125 with an oversize Braking rotor kit. Also the short orange Galfer brake line. 1 finger stoppies. It made a believer out of me.

My build isn't done yet so I can't say for sure, but I bolted up a 2009 Kx 450 front calliper - was told it makes a good improvement and allowed me to run a newer style brake routing vs. under the fork leg which came with the bike.

So the wife bought a big rotor kit and some grippy pads for my birthday.....along with the CR style 04 up hose I got just a while back. I'm planning to ride Monster this weekend if the weather cooperates. I'll post a ride report after.
I may have to find an EBay Brembo master.

Update:

So I got it bled and broke in and took it to Durhamtown Friday. The track was mostly dry and hardpacked so traction wasn't abundant but it will put you on your ass without effort. The lever isn't firm like the Brembo system but it is quite strong.
I took it to one of the vacant camp spots and got a little speed up and grabbed a handful...it will stop!!

Thanks for the tips guys.

What caliber bracket did you use? standard RM125 or the KXF bracket? i want to upgrade the stoppers on my RM125 aswell, I'm thinking a Motostuff 280mm kit with a brembo front master cylinder, i see you can get KXF callipers reasonably cheap on eBay. might buy one if it works out...
