hayabusa rear master (size?)

[Ed74mnd]

guys,

i have used a GSX master cylinder to activate a hayabusa rear caliper.

the GSX master is 14mm bore. (9/16) in old speak.

Does anybody know what bore etc the hayabusa master is?

i seem to have alot of travel in the pedal .. hopefully they are the same.

Cheers

Ed

found the answer...

hayabusa = 12.7mm bore rear master.
gsx = 14mm bore rear master.

my pedal should feel harder with les travel.

it actualy feels softer with more travel so means there is air in the line.

Cheers
