    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Looks the same as the GS1100G MC on my bike. I have access to a brand new one for $20.

Is it ok for use on a GS1100??
 
If they both use the same number of calipers it should be fine.
 
Thanks guys. I had tried compatibility of the whole unit not just the pistion and got different numbers but yes, the piston is the same so it should be fine.

There is also an new OEM RF900 MC for the same money, i might just grab that as well

Darn cheap New OEM MC's :D

Cheers

Master should have 5/8 cast into the body if it's for a dual disc setup. 14mm is for single disc (which what the 550 used in the US market other than the 550M Katana).

My '85 550E has dual front disc brakes...
 
My GS1100G MC piston is only 14mm and once modified to remove excess lever travel it works real good.
