GT750 Master Cylinder

Post by TGladders »

Hello all,

Im looking for a GT750 front master cylinder, for a twin disk set up. You can buy patten ones on eBay but you have to wire a new brake light switch in, is there a kit for that?

Cheers, Tom

Its not for a twin disk set up, a dual disk master cylinder should have a D cast into it

The same switch fits both.
Plus the D master cylinder makes a single disk work better - or fit one from a GS1000 or Bandit 1200 which are better still as they have bigger pistons.

Cheers, Al, I'm converting the front of the 550 to twin disk so I need the correct larger master cylinder

I don't want the non period look of the bandit m/c, I'll look at the gs one

There's one on the hippo + calipers and the brakes are just dandy!
Bandit 1200 m/c on the 550A + gs1000 calipers and gs550 wheels (3 discs) stops just fine!
GS 550 swing arm fits without mods using same swing arm pivot bolt. Anoraks go spare!!! :lol:
