Frando 15mm radial master cylinder. Ideal for supermoto, or bikes with a single front brake caliper -- however, a number of bikes (like my Triumph street triple) use 14mm convential master cylinders, of which this would be a nice upgrade. This is not cheap chinese crap -- they are made in Asia, but have been used on Isle of Man TT bikes, and there are a few reviews online: https://www.motorcyclenews.com/…/frando-master-cylinder-re…/ https://www.ktmduke390forum.com/…/23938-front-brake-upgrade… Comes with what you see in the pics -- this part has been dry fitted, but removed as I've parted out the project. I also have a 17mm version for sale.
$125 plus shipping... they are 150 pounds new plus shipping from the UK: https://www.venhill.co.uk/controls-amp-handlebars/hydraulic-controls/frando.html
I'm thinking this might be a nice upgrade (if it's allowed) to a Ninja 400/R3 as well... not sure about motoAmerica rules about this stuff...
I race a KTM RC390 with a Frando master like the one for sale. Highly recommend the conversion. The Frando unit is very well made and works as good as the Brembo I had on a previous single.
