| For my 888 I will be using a matching pair of brake and clutch master cylinders from an ST4S that look near identical to the originals on my Strada but are just bigger bore, so pump more fluid.
I thought about going down the radial route but I've got the same sort of ST masters on my ST2 and they easily pump enough fluid for the 4 pot, pad-per-piston P34 callipers that I've got on that bike. The brakes on my ST are awesome, easily enough to outbrake other folks on trackdays so I'm expecting the same type of master cylinder to work just as well on my 888. They've also got the advantage of being cheaper and not fouling the clocks.
Just as well they're cheaper 'cos I've just bought a set of brand new 40mm fitment billet Brembos, so the ST masters will be squeezing a set of Mr Brembos finest. |
