Surface area has nothing to do with stopping power. Coefficient_of_friction and force applied is what determines stopping power. A rotor the size of a penny and a break pad the size of needle would have the same stopping force if the same pressure is applied.
However; that set up would melt and meld together as soon as the break is pressed. Larger pads and rotors are for heat distribution. So this set up should be fine as far as stopping the bike...
Unless the rotor breaks. Then you're screwed.

1981? CSR 1000 -- I'll figure it out soon enough.

May not have too much affect, but I believe the stock kawi drilled rotors were ballanced.

Coefficient_of_friction and force applied is what determines stopping power.
I believe you forgot to take into account the increased leverage available due to the larger distance between the caliper and the axle centerline with a larger rotor. That has a very large effect.
To illustrate:
There are two bikes here, GPz750 Turbo and KZ750 twin, both weigh about the same, have same diameter master cylinder, and same calipers, but the Turbo has 10" rotors while the 750 twin has 12" rotors.
And the 750 twin will easily stop faster in a shorter distance than the Turbo in side by side comparisons.

I'm sure the bike stops well enough for not all of us are driving at 100mph plus on a regular basis.
The guy/gal probably drives his bike as I plan to do (when project completed) where keeping to the speed limits (+/- 10 mph), leaving enough distance between me and the car in front of me and keeping an eye on my surroundings due to all the BS people on their cell phones not paying attention...

that sprocket is pretty cool looking !That won't break and it looks cool!
Some of you may remember the sprocket i made, it has held up great with no real signs of wear after 3k miles!
Still recovering,some days are better than others.
