R1 / R6 Front Master Cylinder
« on: 09 July 2018, 06:47:42 pm »
Fairly sure it's been covered before but I just wanted to say that I've recently changed out the front brake master cylinder and the difference is substantial.
Horrified by the price of Brembo aftermarket units, I fitted a 16mm R1 radial master cylinder from the 2004-06 model. I believe the R6 master cylinder from 2008 onwards are virtually the same and are also a relatively straight fit. Costs around the ton and worth considering if your bike is soon due for a master cylinder rebuild / refurb.
Braking is always a subjective thing but I have to say that there's a lot less effort required to build stopping power towards max....yet somehow the sensitivity is still there, certainly enough to avoid overloading the forks / locking the front up.

Recommended!

Is it the r1 5vy model ? Do you have pics to show it mounted?
If it's broken, it's not fixed.

Yes, the 5VY master cylinder, 2004-06.
Have pics but need a new image hosting site since Photobucket started charging!

Try Flickr - similar to photobucket although not so straightforward to use. Seem to have to click on lots of different links to do the same job. Once you've learnt how to use the site it is easy.

How did you mount the brake fluid reservoir?
