Anyone have any experience with them? I just ordered a set from racetechtitanium for my KTM

No experience but the colors prob look sick as fuck after a few heat cycles

That’s what I’m hoping for +1lb reduction per wheel.

$308 for the set with Friday’s sale wasn’t terrible either

Should cope better with hits as well you'd think.

Might be more brittle? Although I wonder how susceptible they are to warpage.

If you're not mixing gas, you're not haulin ass.

Interesting. I don't have any experience with Ti rotors, but I would think they would be susceptible to galling. This is the first I've heard of using titanium for a brake rotor, so I'm interested in hearing how it works out.

I’ve heard rumors the coefficient of friction lends to a grabby feel on road racer bikes.

Post up pics when you get them!

I've got a titanium piston in my rear calilper. Apparently they don't transfer heat as much as steel I read.

I didn't think titanium rotors were AMA legal ? ...maybe its Carbon I'm thinking of

Would carbon discs be possible in MX? I know in Formula1 they don’t work too well until they are heated up, which they are flying around a track and braking to achieve that. Don’t know if that’s possible in MX?

Oh no.
Yesterday I didn’t know they existed, now I can’t live without them!

I’ve got cast iron (Axis) discs on two Supermoto bikes. They are meant to be the next best to carbon for road race applications. Heavy, but great feel.

Funny this topic came up. A friend of mine from London was just telling me that his dad used to make carbon discs for the MotoGP guys in Europe. When he was riding 85s his dad made him a prototype setup. He said it was insane but looked crazy.

I’ll see if he has any photos....

My friend said that from what he knows his dad and Mitch Payton were the only ones that tried. The problem with carbon discs in MX is that they have to get really hot to work. The MotoGP guys can just get them hot enough when it’s wet out. The positive is that they never fade but on the other hand wear out super fast.

I doubt carbon fiber rotors would be any benefit in MX, with current tech.
The improvement when hot is worth it in road racing where riders are braking from 320kmh to 60, every lap.
Slower tracks they run covers to keep the heat in, and some racers use steel discs in the wet.
They were banned in World Superbike years ago on cost grounds.

I don’t think anyone is suffering from front brake fade, or lack of power in MX. (With top spec brakes in good condition.)

If the technology improved we might see them in MX for the weight saving.

Those Ti rotors look pretty cool, and light!

I wonder how the friction coefficient is? What pads are recommended?

|

Formula 1 rotors are not made of carbon fiber, but carbon. If you heard Steve Matchett describe how they are made, you will quickly conclude that no non-factory SX / MX person could really afford it.

Carbon discs wouldn't work in moto. They would never come close to the operating temperature.

Like some have already mentioned. MotoGP teams put "disc guards" on their bikes when they face colder conditions to keep the temperature. In full wet conditions they use steel discs because it's impossible to get the necessary heat in them.

There here but so is winter. Won’t have a report for a while Photo

They look the goods!
Do they feel noticeably lighter?
