ADCUT brake discs
Hey:
This was a project I was working on over the fall/winter, I now have a reasonable amount of miles on it for a chance to report my findings:, so far its all been a good improvement with no downside as of yet. See what you guys think of this.

Very nice looking discs
BUT I wouldn't fit them - there doesn't seem to be enough "meat" for the pads to grip to slow you down............maybe I'm just old fashioned.... and these are heavy old girls.
Perhaps a report on stopping distances compared to standard discs would convince me.
I may be in the market for a new pair of discs if I can't find the shudder in my front end....
so if they work well, may be an option....

Look amazing but I'm not sure there's be enough mass to them either & I'd be concerned
about concentrated overheating on the pieces that the brake pads do actually grip. My
opinion they might actually come apart under very heavy repeated braking.
Just a personal opinion & observation is all

I have to agree with Sprock and Shadow. What they said is what came to mind.
Stopping is done through the transfer of energy using the principles of the conservation of energy. In this case you are transferring the energy of a moving mass to heat energy. That heat is produced by the friction between the pads and the rotor. The heat is then dissipated to the surrounding air as it comes in contact with the rotor. The energy that was in the moving mass, that is now at rest, would then be in the heated air.
By cutting away to much surface area, there would be a lack of energy transfer to the disk due to the lack of frictional area between the pads and rotor. The rotor would not heat up. This would cause poor stopping action.
A good braking system puts a lot of heat into the rotor but gets rid of it fast. It's a find balance. If you aren't having stopping problems, you may have found the balance or be slightly on the other side.
Edit: They also may be weakened due to the lack of material as mentioned above, I'd be a little careful.

Well, I find them sexy..............
And I think would be willing to give them a go.
I did this..........
To my Kawaski GTR1000 about 35,000 km ago.
Laser cut stainless discs with Honda CBR929 (?) Nissin 4 spots. As you say, the CBR1000F is a heavy bike, but the GTR is comparable if not a little fatter!
Tranformed the braking to two finger haul downs!
Touch wood, not a problem with the set up.
Cheers, SB
