Single sided front disc brake

I want a Ducati that is as minimalistic as possible, so I wonder how far I must go to maintain the same braking effect that I have today with my 1ks2r but with only one brake disc? Will a Braketec cc and a Brembo monobloc be enough?

I don't know if that will give you the same braking, but it will most likely be plenty.

I have a friend that did that on a track bike and couldn't keep rotors from warping from the heat. I think it would be fine for a street bike.

I know he went through a bunch of discs, but did Eric ever try the carbon/ceramic discs like kopfjager has on his bike? They're kinda designed to work at metal-warping temps. I've even heard that they don't work all that great until they have some heat in them, which could be my brain playing tricks on me.

I can't wait until Marquez gets on his level and makes Jorge trip on his tampon string.

You're right..they don't work until they're hot, which is why he didn't put one on his street/track bike.

Sorry, I mean a single Braketech CMC rotor.

Try it...

it should have plenty of stopping power. The dual discs are way more than the bike needs for the speeds it is capable of.

The single disc on my M750 stops stupid fast.  Even two up.  Unless you're constantly tracking the bike you're fine.

I've found that a single rotor gives about the same power as a dual rotor for a given caliper type, rotor size etc (provided that the MC diameter is matched to caliper piston area).  The big difference is in how much braking you can do before they get too hot and fade or warp.  Not usually an issue on the street, but you can cook a single rotor on the track on a heavish bike (heavy compared to say 250lbs single rotor supermotos).  For a street bike, especially one that's generally under 100mph I think a quality single rotor system could work quite well.

I think I would agree that it is possible to do so on the street, so long as you weren't pushing it all over the place or riding down a crap-ton of hills regularly (and still, you can mitigate lots of this by being quite aggressive on your engine braking techniques).   you might reduce the likelihood of warping by making sure you pick your pads carefully, and considering a 330mm rotor from the 1098/1198 over the 320mm rotors (thought being: more disc surface area for more heat dissipation).

For a minimalist look, the alternative (using your 65mm fork bottom brake mount spacing) would be the Beringer 4D setup - teeny-tiny rotors (4) and much less inertia for great turning and apparently *very* good braking (so I hear, need to get another duc to try this out on one day).   You can get the parts in the anodizing color of your choice (red, blue, black, etc) and even chrome-polished (not sure about that last one on the 4d system).   Anyhow, the reviews I've read say "they are really a great setup with regards to stopping, and the reduction in rotational inertia is obvious during turn-in"   and I know they look bad ass from staring at them long and hard. I just don't yet have FHE.

It is for street use only,97% solo the rest 3% is with my daughter so at a much slower pace with her on.
Any one with FHE with the Brake Tech CMC rotor?
