OEM Rear Brake Master Cylinder Piston Size

[junior varsity]

There I was making my holiday wish-list, perusing various catalogs, when in the Ducati Performance catalog I spied the 13mm Rear brake master. This brought me to the question of... wonder what the piston size is in the oem?

I could find that the size on the 999R is 11mm. Don't know what that part no. is also used on. (Not by a computer with necessary resources).

Stock is 11 mm.

I see.

I just 'scored' a billet rear brake master on the fleabay from Discacciati for the project, its piston size is 14mm, and I saw the DP catalog shows an 13mm. (Both listed as 'high performance/upgrade' rear master's)


Their Hypermotard rear brake system looks super cool:

I won't spend much on rear brakes, but will love to see pictures if you do [moto]
