Couldn't find anything from Kawasaki but I found an online catalog from jtsprockets that mentions this.

The Z125 was listed under 43 Teeth and I assume the Pro has the same amount.

Front Sprocket 14
Rear Sprocket 43
Thanks. I should have thought to check there.

So, that gives the Z125 a really low gear ratio of 3.07 as compared to the Grom's 2.27.

Should mean the Z will have much better acceleration but lower top speed. That's a trade-off I could live with.
