To answer your question.
Yes they do. And so does Brembo.
They are made to be used on stunt bikes. But with this type you have to add a small brake fluid reservoir and they are very expensive.

Would the reservoir mount on the top of the master cylinder like a street bike or in a remote location with a line?
