Hi,
The banjo bolts on original Morini master cylinders are M10 x1mm pitch. Most Japanese bikes (and their pattern parts suppliers too) use an M10x1.25mm bolt.
As Steve said, if yours is a Sport, then the overall size of a replacement needs to be checked as, usually, when you fit it the banjo bolt will be very close to the speedometer. Would be worth looking for one that has the hose fitting on the front rather than on the end as that will give you a lot more freedom to move the clip-on and brake lever position where it is most comfortable for you.
Many owners have downsized to a 14mm master cylinder. You will get a much nicer front brake in both feel and power if you do so.
