Member Contributer BusyLittleShop Posted April 1, 2013 Member Contributer Share Posted April 1, 2013 MotoGp technology for the street... Sicom's Ceramic Matrix Composite(CMC) rear disc is light as carbon but sports an everyday workablealternative to the heavier steel disc... the CMC disc stops from theget go no matter wet or dry... someday I hope this technology maybecome to norm for top shelf bikes...Check out Sicom's other line of CMC disc for motorcycleshttp://www.sicom-brakes.com/html/motorcycles.htmlSicom's (12oz / 340gm) CMC disc was for a Ducati 1199 Panigalebut this is how I modified it to fit Mr.RC45 employing my Mill andRotary Table...I wanted dead nuts accuracy so I located the center of the Ducati's110mm bolt circle with a wiggler and then wiggled the Honda's 120mmbolt circle...The bolt hole was cut with a .312 Carbide Ball End which comes out theother side without chipping...To size the bolt hole to fit perfect with the Titanium fastener I useda stone hone...A .500 Carbide Rodman bit was employed for the other holes to lightenthe 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 45º to give the edge a crisp 45º cut...Finish weight was 7oz (198gm) thats a 1 lb 14oz (849gm) savings overthe stock Honda steel...The sinter pads that came with the CMC disc are milled down to fit my4 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... 1 Quote Link to comment Share on other sites More sharing options...
Member Contributer apexandy Posted April 1, 2013 Member Contributer Share Posted April 1, 2013 That is really neat stuff! How much does Mr. RC45 weigh now? And what were they stock? Quote Link to comment Share on other sites More sharing options...
Member Contributer Mohawk Posted April 1, 2013 Member Contributer Share Posted April 1, 2013 Hey Larry, as always excellent work. Love it. I didn't see your CMC front upgrade before, is there a thread for it ? How long did the mods to the disc take you ? That is some serious machining. I've never seen the CMC material in the flesh, is it more like a metal or a ceramic ? Keep up the good work. Quote Link to comment Share on other sites More sharing options...

I've never seen the CMC material in the flesh, is it more like a metal or a ceramic ? Keep up the good work. Thank you... My CMC upgrade was in 2007 and its no longer on the site... I've been working on the CMC rear mod for 2 weeks... CMC is more like ceramic than metal... and I might add very dusty... Nice is it a smooth brake feel or is it grabby? I haven't tested hopped the new rear CMC but I've been using Brake Tech's CMC disc on the front since 2007... This all new composite material offers the best features of premium iron rotors with the incredible lightweight of carbon and none of the Carbon/carbon problems of thermally sensitive... unlike Carbon carbon they are not hygroscopic so they perform the same as cast iron in the wet no more or no less... my experience is all positive with terrific feel and feedback at the lever regardless of out side air temp... the only caution is to make sure your brake fluid is fresh (no brown discoloration) because they will heat up the pads... I boiled my Motul Dot 4 during numerous 140 to 0 stops to bed in the pads as advised by the break in flyer... Quote Link to comment Share on other sites More sharing options...

Member Contributer eastbowl2 Posted April 4, 2013 Member Contributer Share Posted April 4, 2013 Amazing work. Of course, not knowing anything about such work, my opinion is worth little. But if I was I pro, I bet I'd still be impressed. Quote Link to comment Share on other sites More sharing options...
