In the garage deciding what to do first!
With the difficulty and expense of fitting the correct Brembo front brake master cylinder I just wondered if anyone has installed the Honds CB or Suzuki GS master cylinders - the ones with the round top reservoirs.
They look almost identical to the Brembo type..............

I do need one for my 3CL and my local scrappie has just got in a Suzuki GS somethingorother bike.

I want to use the standard brembo calipers aswell - still loking for a pair (Ceriani type) though
 
Shouldn't be much difference as long as the hydraulic AND mechanical ratios are similar.

Most jap M/Cs for dual discs have 9/16" pistons, perfect for the twin P08s!  Just need to check lever dimensions are not too far off...

Be prepared to be flamed if you really do it though... :D

Once used a 1/2" jobbie off a Yamaha LC, wondered why it coped so well till I measured the lever and compared it to the Brembo item.  Reservoir was quite small, emptied it several times due to extreme pad wear on alpine trips!

This is a good site for ratios.

I've fitted a m/c off a Firestorm on my RGS (with matching clutch) cos the rebuild kit for my o/e Brembo one wasn't available.  I don't give a hoot about originality, but if you're choosing another m/c and want better performance then as Greg said, a 14mm one gives more feel. I did this on my 180 and even kept the same m/c when I went to 4 pots, which have a greater piston area and feel sooo much nicer than wooden P08s.
 
.... another 14mm option is Yam FJR.

I use a 1/2" from a Bandit (400cc I think) on my Jota. Works well, but some may find it a bit much. I like a light squeeze and lots of lever travel.
