You guys may have to resort to finding an engine with approximately 48mm bore (think the twin is 48.05), same ring ring thickness, then adjust the ring gap as required with a dremel.
Not ideal, but what can you do.

Quick search shows some yamaha and kwaka's have bores around it

Good Morning all,

Rings are available from Nornda Automotive who were also known as JP Pistons, I have had STD rings made in the past and a friend very recently placed an order for more. They should do oversized as well, I have never seen a Twin with oversized rings yet. They never lasted that long in service.

Give them a call
