Don - my fender stay would have fouled my conversion as well, so I used the same CB900C front fender Tom refers to. Looks and works great. The only thing that I wish I'd done differently was used 30° fittings at the calipers. I think that would have fit better than the straight ones.

I see a white box with a gray circle in the middle and the circle has a horizontal line in it. This typically happens when people try hotlinking pics from the cloud.

Hi, i have 77' gl1000 project going on here and i would like to upgrade the front brakes. I have also 84' VF750F parts bike and I thought to use its brake assembly. What year and model brackets i should be looking for for this kind of setup?

Thanks

Page two on this thread has a list of left brackets that fit, if the left fits usually the right will also. The calipers may have the piston size stamped on them somewhere. There reportedly were four sizes including the bigger ones @ 30 and 32 mm. I'll see if I can lift some more info on it.

I used the list on page two and these lifted from sohc4.net to cross reference. All of these bikes use the same bracket part number. There is a problem with the 81cb900F brackets. Sometimes they have the 1980 bracket which doesn't work. I suspect it was a running fork change and early 81's have the 80 forks.

Thanks, this is very useful. I used www.cmsnl.com to track the models that uses the same part. You just have to insert part number and it shows what models the part fits. For example 45210445632:

Two of us bought 81 cb900F brackets and got 80 parts. I'm thinking they must have early/late 81 forks.
