Topic: Looking at getting a new master cylinder for my cb500. Suggestions?!

[Maximiliaanvk]

Hi everyone,

I need to get a new master cylinder for my CB 500 1972. I want to keep the same calliper and system. Just want a smaller master cylinder so it will fit on my handle bars. Currently its all a bit too big and won't really fit. 

I was looking at spending as little as I could with having some sort of an upgrade. around $100 would be fine and second hand doesn't bother me.

An suggestions on what could work for me? I have been looking and can't find any replacements that will definately work with my current system which is connected to the bottom triple tree. Please help!

Thanks.
Max

You can get a brand new 12 or 13mm Brembo for $120 and they're quite small. Nice master.

Can you post a picture? Some older BMW bikes (and I'm sure others) use a remote MC that tucks under their tanks. That type may well work for you too.

My friends 254 guzzi has a cable to a mc and reservoir under the tank.

I think some guys use the Ducati style reservoir they are small amazon has them cheap.

How does the braking power compare to a radial master cylinder? I'm in the hunt for a new MC and want to max out the stopping power on these old hondas with a single rotor (ground and drilled).
