Carbon-Ceramic Brake Discs for Motorcycles

A direct replacement for the steel disc

The carbon-ceramic disc is built to the diameter, thickness and mounting of your original steel disc. The factory caliper, wheel and hub stay as they are.

• Any motorcycle. Send us the model and year, and we confirm the disc dimensions with you.
• One disc or a pair. Order a single disc for a bike with one front disc, or to replace one side only.
• Our own pads. We supply brake pads with a compound made for carbon-ceramic. Pads made for steel discs are not compatible and can wear the friction surface.
• Custom styling. We choose the disc shape with you, and the look can be customised.

CCB or CCM

Disc thickness decides which material we use. CCB has a silicon carbide coating on its braking faces. The coating needs enough disc thickness beneath it to bond strongly.

Disc thickness	Material	Used for
More than 6.0 mm	CCB	Cars, motorcycles, go-karts
Less than 6.0 mm	CCM	Thin discs, where a coating would not bond strongly enough

Disc construction

A motorcycle disc is a floating assembly. The carbon‑ceramic ring is not bolted solidly to its carrier: bobbins hold it with a small amount of play, so the ring can grow as it heats and centre itself between the pads instead of pulling the carrier out of true.

• Friction ring: long‑fibre carbon‑ceramic (C/SiC), with a silicon carbide coated braking surface.
• Centre bell (hat) and carrier: 7075‑T6 aluminium alloy, machined to your hub, bolt circle and offset.
• Bobbins: Grade 5 titanium, Ti‑6Al‑4V. The bobbins are what joins the ring to the bell, and they set how much the ring can float; circlips retain them.
• Bolts and hardware: Grade 5 titanium, Ti‑6Al‑4V.

We use 7075‑T6 for the bell because it is the strongest of the common aluminium alloys, at roughly 572 MPa tensile against 310 MPa for 6061‑T6, and the bell has to pass the whole braking load on to the wheel in a section thin enough to stay light. The bobbins and the bolts are both Grade 5 titanium, at around 895 MPa, stronger than the stainless hardware normally used — which matters most at the bobbins, since on a floating disc they are the only path from the ring into the bell. Neither metal contains iron, so neither rusts. With a carbon‑ceramic ring you get a disc with no corroded ring, no corroded bell and no rusted hardware.

Titanium and aluminium are a galvanic pair. Keep the bolts at their specified torque, and check at each pad change that the bobbins still move freely.

Sizes

Outer diameter from 220 to 350 mm. Every diameter is available 5.5 or 6.0 mm thick, and from 320 mm up we also make the ring 6.75 or 8.0 mm thick.

Dimensions are confirmed against your bike before production. If you do not know your disc size, our reverse engineering guide shows how to measure it.

Bikes we have built for

Discs we have already made. If your motorcycle is not listed, we can still make one for it.

Tested on track

Our rotors are tested on track, not only on the bench. They run on race bikes in real sessions, which is where a disc is asked for everything at once: repeated stops from top speed, heat that never fully leaves the ring between corners, and hard braking carried right to the apex.

Track running is how we check what a static test cannot show — that the bobbins still float freely after a full day of heat cycles, that the coated surface wears evenly across the swept band, and that our pad compound stays consistent once the ring is hot.

What comes back from those sessions goes into the next disc: ring thickness, the shape of the carrier, the amount of float, and the pad compound we supply with it.

How we work

1. You send us the model and year of your motorcycle.
2. We verify the disc data with you.
3. We select the shape of the carbon-ceramic disc. Style customisation is available.
4. We send you a quotation.
