(CMC) rear disc is light as carbon but sports an everyday workable
alternative to the heavier steel disc... the CMC disc stops from the
get go no matter wet or dry... someday I hope this technology may
become to norm for top shelf bikes...
Check out Sicom's other line of CMC disc for motorcycles

Sicom's (12oz / 340gm) CMC disc was for a Ducati 1199 Panigale
but this is how I modified it to fit Mr.RC45 employing my Mill and
Rotary Table...
I wanted dead nuts accuracy so I located the center of the Ducati's
110mm bolt circle with a wiggler and then wiggled the Honda's 120mm
bolt circle...
The bolt hole was cut with a .312 Carbide Ball End which comes out the
other side without chipping...
To size the bolt hole to fit perfect with the Titanium fastener I used
a stone hone...
A .500 Carbide Rodman bit was employed for the other holes to lighten
the disc and give it the shape I wanted...
I used a Ceramic cutter to trim off the excess diameter surgically...
I angled the Mill head 45? to give the edge a crisp 45? cut...
Finish weight was 7oz (198gm) thats a 1 lb 14oz (849gm) savings over
the stock Honda steel...
The sinter pads that came with the CMC disc are milled down to fit my
4 pot Gp Brembo...
You have to feel it to believe it but my finished Ceramic Matrix Composite disc only weights
7oz...
Now my rear disc is CMC like my front disc...
