G'day Marcus.
The short answer is no. The comp rings are 1/16" and oil ring is 1/8" thick which is common for pommy 4 strokes but the depth can vary. If the pistons were made for an A7/10, rings made for the same will fit.
No way of telling what brand you have. I try to get original Hepolites if possible. At the moment I have Italian Mondial pistons with Hep rings made for a Triumph 650. They were a little snug in the grooves, a light rub with wet & dry fixed that.
Cheers

where possible I run 3 or 4 piece oil scraper rings, (preferably 3) as they do work more effectively than the one piece type that take quite a while to settle down and in a worn bore often don't.
