Yepmy bad... m10x1.25 is the banjo size (m10) and thread pitch (1.25). the stock master cylinder is an m10x1.25. the aftermarket brembos and other name-brand european brands are m10x1.0. from the looks of it, you have a 1.0 double banjo on the right, and a 1.25 single banjo on the left.
hope that helps you figure it out. most bike shops carry banjos, and MOST of the time, they're universal. so just find one that fits and run with it.
