I've tried all the normal mods- stainless line, Braking rotor, good fresh fluid, braking pads, etc., and I just can't get quite happy with the front brake performance on my CRF. I doesn't help that I rode a KTM all of last year. I'm pretty much convinced that the Nissin caliper just flexes. So I have decided to fit a KTM set up to my Honda. I've searched and searched for any possible way to do this but haven't come across any solutions to get this done. Does anyone have any input, or know of anyone who has done this? I'm guessing that this would be a common mod in Europe as they are so pro Brembo products(rightfully so), so there has to be a caliper bracket out there. Anyone have any leads?
Any others? Hard to believe there aren't more opinions out there.
I have a friend who is a machinist and he has already offered to make me one, problem is I want to get it on my bike this decade. You know how those buddy side jobs go. :-)
I have 3 different YZs, and I run the 2008 honda brake on the front of my oldest bike (a 2002 YZ250).
In 2007 (2008 on the two stroke) Yamaha upgraded their entire brake system. It's worlds better, and although not equal, it's on par with a stock Honda.
From playing around with all of this Yamaha and Honda brake stuff I learned that the master cylinder is where a lot of the improvement comes from.
There is a small hole that lets the fluid into the cylinder from the reservoir. The position of that little hole vs the rubber cup on the piston is crucial in where the M/C picks up pressure. Obviously the rubber cup and the stock nylon braided hose have a lot of elasticity which translates into spongy feeling brakes. Think of it like the port in a two stroke and how that effects the compression ratio.
Bore diameter of the caliper and the M/C combined with the leverage ratio at the lever are also playing a factor... I doubt Brembo and Nissin units have the same specs. A Kawasaki Nissin vs a Honda Nissin is probably a bit different. Yamaha upgraded to an intermediate link in their 2007+ M/C... It makes a difference. Honda has a similar link built into their lever.
Another area is the runout of the front rotor and how well the caliper pins align and float. If the rotor has any runout at all, it will squeeze the pistons back in by at least that amount. If you check your rotor with a dial indicator you should have more than a few thousandths of an inch. Floating rotors help with this aspect, but they seem to bend a lot easier.
Fluid... If you're running the standard DOT 4 brake fluid, it is a hygroscopic and will attract water. So ever 3 to 6 months you should completely flush the fluid out of the system.
Another option is to tear down the system, clean everything 100% free of the DOT 4 fluid and use the silicon based DOT 5 fluid as it doesn't attract water. I think it can be a little tougher to bleed the DOT 5 sometimes, but a vacuum pump bleeder works great because the low pressure causes the air bubbles trapped in the fluid to expand.
If you want to test for caliper flex, get a dial indicator. Put it on a ktm and test how far the caliper spreads when you pull the brake lever. Probably a very small amount of flex... Now check a Honda, etc. If they're within 10% of the same amount of flex I wouldn't worry about it.

I know, I know...you've done all that...well...not really. Like I said, "Galfer".
Btw, Chad Sanner @ 11-Ten knows how to put that Brembo on a Honda...

the one on the left is a brembo!
There's a lot more to be desired in terms of control and feel in a brake than just stopping power.
Pit Row
That amount of stopping power on dirt would put you on your face faster than James Stewart on a grass start.
I've done a bit more research today and bottom line is it will be tough to fit a brembo caliper to a my bike. After talking to some friends in the industry, I'm gonna mount up a brembo master cylinder, mount new Honda pads, and flush with some new AP fluid. I'll see where that gets me. If I'm not satisfied with that, I'll probably give the ride eng caliper a try. Thanks again. :-)

Concern now is the rear. You can go to my profile or my bike check and look or here's a link to a picture https://p.vitalmx.com/photos/users/54819/photos/96494/s1600_20161127_15…
Both sides have renthal intellilevers which I recommend because you can adjust the reach all the way out to get the hardest longest pull to get them bleed perfectly and you can adjust them to the perfect place for you and their lifetime warranty, both sides also have red works connection reservoir caps and red works connection rotator clamps and yes that's a 2016 kill switch I'm running on my 2007 cr250, as far as I know I'm the only one ever to do that, it just looks and functions better in every way, the light is pointless but IDC. Like I said, those of you who would want front and rear Honda to brembo caliper carriers give me your vote cus I'll have a batch made instead of just 1, your chances of finding an eleven10 mods one are slim to none, I talked directly to the owner and he has none and one made a small batch, ran them on their race bikes when the team was big and sold them to the public for a short time and only sold a couple, if I get interest I start my own site selling full kits, caliper, brackets, line and hardware all in on kit, my hope is to do Honda first, the Yamaha because I have a yz250 to use to make them and the Suzuki/kawi because I believe they are still the same rear carriers and fork lugs, I hope to complete the front caliper carrier for Honda to brembo first and then do rear honda caliper carrier to brembo with a rear master cylinder from Honda to brembo also first tho as I believe Honda riders would be the largest benefactors
This is a photo from the rear so you know for sure they are 2017 brembo master cylinders by how the clamps are on the top
Hole-eeeee-she-iiiiitttt. This mofo STOPS! Most would call it overkill but I like it!!!
