Hi all. Looking at getting a slightly larger-bored front brake master cylinder, based on discussion here (of course). Does anyone know the bore size for the following:

Ninja EX500 (there's a thousand of them on ebay)
Ninja ZZR 1200

(and here's the curly one):

Vulcan classic VN 1600 - but I also want to know if the brake lines will connect up to this unit, which is oriented differently.

You need a 1/2" bore master cylinder, to go up one size from the stock 11mm.

I got one from a Kawasaki ER5, the stock lever and mirror work. Suzuki GS500 should also be 1/2"

I would imagine that the ZZR has a bigger bore than 1/2", probably 5/8". That would be useless on a single disc bike.

The Vulcan classic probably has 25mm handlebars, if so the m/cyl would not fit.
