Radial Mount Brakes...

Alright...question. What the F are radial mount brakes? I read that all the new bikes have them. My gixxer, being a thousand years old, doesn't. So can anyone explain ?

I've rode a new gixxer w/ radial mounts. The stopping power was incredible...

Good question. Never really looked into it. i just asumed it was the way the caliper mounts to the inverted forks at the bottom peice near the axle. Kinda like your is. But I don't know for sure.

That helps. The way I understand that article is its the way they are mounted at the bottom of the forks?

And thus gives it better feel b/c of more consistent pressure on the pads...I think.

That's what I gathered, because of better alignment.

That article justified the deisgn, but does not describe WHAT makes a radial mount.

In a traditional mount, the mounting bolts are perpendicular to the rotor. Radial mounts place the bolts parallel to the rotor.

Its not where they are mounted... its how they are mounted...

They are mounted forward. Bolting the caliper forward towards the forks. Not thru the caliper towards the rim.

The latter way pushes the caliper one way or the other mis-aligning it to the rotor.

Look at the pic of the caliper on the fork.




Now look at the front caliper on my old 9R.

See the difference in mounting bolts?
