Suzuki 2 Strokes

What size bore does the single disc master have??? 13mm maybe?

Anybody?

mine was 14 mm. In the end I used a universal one off Ebay as I was building a Cafe Racer I didn't mind not going standard. I did try a 10 mm one, but I had too much lever travel.

here is the one simmilar to the one I used.... but there are loads on Ebay, search on "universal master cylinder 7/8" assuming your bars are 7/8 diameter.

If you are looking for an aftermarket replacement, then this discussion on master cylinder ratio is worth reading before you make your selection.
