    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...

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.

caliper upgrade

Forum Newbie
I am thinking of upgrading the brakes on my 1980 gsx1100et, are there any calipers which fit straight on what can be recommended, thanks.
 
Nothing that will fit straight on. A member here, Salty_Monk, sells some nifty conversion brackets though. Try the search function there are literally dozens of threads from happy customers.
 
I read that the Brembo F08 calipers could bolt directly on a 1000. The F08 has twin 38mm pistons. Am I misguided? AFAIK the caliper bolt patterns are the same between 79- and 80+

They'd need to be sliders, as there's not enough room for opposed piston types. At least, none that have been found so far.
 
Looking at pictures that F08 looks like it would be too thick too... :)

I haven't found a good solution for an opposed piston yet. I suspect the only models with enough distance between the fork legs would be the 83+ 750/700 models with the 16" wheel. The GS1150 has opposed pistons & I suspect that it is the same front end. The 1150 Hub is much wider to push the rotors out.

The GK models with the larger diameter legs might also have more distance.. I've not measured one to find out. :)
 
On a related note...
The XJ9 legs are 37mm and would fit straight on to the GS. The XJ uses opposed piston calipers.
If I ever bend the front badly enough, I'll look for an XJ front end. I honestly can't say I've had any reservations about the XJ handling and braking.
