Hi everyone,

Having done my first track day and subsequently running out of brakes, I quickly researched, bought and installed new pads (EBC HH).

Thinking that is all I could do to improve the brakes (I haven't looked into brakes before), by chance I met a lad who has a Scrambler Cafe Racer.
I was surprised to the amount of differences between his bike and my Icon as I presumed the Cafe Racer was just more about cosmetic change.
How wrong was I! Different forks, 17" front wheel and the other big surprise was that it has a Brembo Radial master cylinder!
I've looked into the parts numbers and cost, wow, Ducati want a lot for that particular set up!
Having researched brakes, I worked out that I would require a 15mm radial master cylinder. However, when I go through the bike configurator on the Brembo website it suggests a 16mm master cylinder.

Does anyone know the size of the master cylinder the Cafe Racer uses?
I know one person on here has upgraded to a radial master cylinder but would like other peoples views etc on it all?

Many thanks.

"Brembo master cylinder" my 2015 Icon has this. Not sure if it's radial tho??? What difference will a 15mm make compared to 16mm?

The 15mm will have less lever force to press - but need more travel than the 16mm - but not a huge difference.

the 16mm has 14% more area - so will need 14% more lever force - but 14% less travel.

I had worked out all the surface area etc of both caliper pistons and master cylinder which gave 15mm as the ideal, just strange that Brembo suggest 16mm?
