I can't help you with your question, I can only say that I've been wondering the same thing. So, I'll be hoping that someone responds to this myself. Anyone??

Later on, Bill

I haven't tried a set of those but I noticed they come with a set of s12 rings that must be cut down to the right size for the s4 pistons. For anyone with the S12 piston set-up (337cc) this might be a fairly cheap way to pick up some new rings plus a couple S4 high rise pistons.

Bill Silver addresses this topic in one of his restoration guides. His comments are to the effect that there are good, bad and unknown quality kits out there, and to shop wisely. I think he mentions the Italian pistons in the 'unknowns'.

Italy is in general very good at producing quality products which depend on machining and metallurgy. I would be comfortable putting a set of Italian manufacture pistons in my CB77. As far as rings go, I wouldn't buy a kit that didn't include rings and a head gasket ready to go without modification.
