New front brake Master Yamaha Roadstar.

[Lucky]

NEW Front Brake master cylinder for sale with NEW lever. Never used. $200. Includes shipping from 85710. USA only.
I purchased this two weeks ago from Yamaha and was not able to use it because it is not big enough for my 4 piston front brake caliper.
This is brand new.
Let me know if you have any questions.

Did you buy this for the r1 upgrade?

[Lucky]

This has nothing to do with R1's.

What orifice size do they require for the 4 piston setup?

[Lucky]

Office size? Do not know what you are referring to.
The recommended piston size is 5/8" 11/16" for the 4 piston caliper.
