Panigale Ceramic Matrix Composite Disc Mod...

MotoGp technology for the street... Sicom's Ceramic Matrix Composite
(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...

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 45º to give the edge a crisp 45º 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...

That is really neat stuff! How much does Mr. RC45 weigh now? And what were they stock? 

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.

Well done Larry, that is another great modification!
Now when will you be competing in WSBK?

Less rotating mass is a very big deal.

The RC45 mad scientist strikes again.

But one soda in your belly on an afternoon ride, and there's your steel brake disc! haha!

seriously, good work Larry, looks beautiful.

Just think of all the soft drinks Larry has denied himself over the years Rob! lol


Nice work on the rotor Larry, I know that cutting that OD was not easy work.

Awesome! It's really high tech.

How much does it cost for this mod?

Awesome! It's really high tech.
How much does it cost for this mod?

the rotor is like 700 euro

Well done Larry, that is another great modification!Now when will you be competing in WSBK?

Never. WIth Ceramic Brakes, Mr RC45 is illegal in WSB.

Steel brakes allowed only.

Nice is it a smooth brake feel or is it grabby?

Love it, thanks for sharing Larry.

More a MotoGP mod than a WSBK one!!

That bike is too sexy to call it a Mr...

That is really neat stuff! How much does Mr. RC45 weigh now? And what were they stock? 

Thanks... 404lbs tank empty and 431 tank full... I've taken 30 pounds off
Mr.RC45 since 98...

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...

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...

Right!   

Now we want of course a picture of Mr.45 doing a "Rossi".............    :cool:

That is a cool pic...red hot!

Master machine work with high tech materials...  Very cool stuff BLS, thanks for sharing.  That must be one happy Honda!

Never cease to amaze me Larry. Beautiful work.

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.
