Yes no problem I’ll take a look. I may have one I can sell you. I’ll chrck this evening.

I’ve tried the brembo master cylinder on the stock yz caliper and 2006, not a good feel. What most don’t understand with brakes is the caliper piston size much match the master cylinder piston size, they are engineered with a specific hydraulic ratio in mind. You may slap whatever master cylinder you want to on your bike and it will...

Use the stock Yamaha line, it’s braided. Honda is not. That caliper and master cylinder would be perfect. You can run it with the stock rotor, which is a 270mm.

The caliper bracket is the same. 06 caliper has bigger pistons. The Honda master cylinder will overpower stock caliper which has smaller pistons. To be correct you need the Honda mastercylinder which is an 11mm piston with the 06 caliper. I’m not 100% sure on what year Honda master cylinder, check the microfiche I think they have been the same...

Yes it will work fine. No problem.

Get the Braking batfly semi floating matched with the setup I posted above.

Find a 2006 YZ 250F caliper and run a Honda master cylinder with the oem brake line (which is braided by the way, just covered with rubber). You will not be disappointed. It’s probably the closest thing you’ll get to a factory brake.
