..of RR's, there are a number of technologies that could have been implemented in the various available RR's, "Mosfet" controlled RR may be configured in a number of ways, generally not as "Shunt" regulation. May well be a synchronous rectifier format, where the voltage regulation and incoming AC voltage ( implied current ) rectification is accomplished by the ( polyphase ) series regulating device(s), low cost implementation could be argued.
As for the new generation secondary batteries, not all that familiar though believe there to be 4 types of chemical compositions with different charging regime requirements. Tangled with various non motorcycle applications for "Lithium" batteries, takes research and bench work to achieve a confident application outcome and resulting predicatble performance, ie not all lithium batteries are the same even in a vertical technology type.
Charging systems and battery that suddenly fail, mode dependent. Fatigue failure a first notion, has merit. Now into the internal type of construction. Have little doubt that SSB are very aware of early field failures, matter of how it is handled as PR or dedicated resolve to make good the after failure efforts.
Test of charging system and battery, Bruce has the many years/decades of experience to call upon, as myself. Over the decades test equipment advanced and the connection of said same equipment, had to be mitigated with "is the test connection modifying what is observed or measured". Classic being AVO meters and their stated sensitivity as "load" Ohms per volt. Long topic there, summation is the test equipment loaded the measuring circuit. No problem, make the measuring equipment high impedance, comes the "VTVM". Ok no loading, now we have a highly sensitive device with long probes, ie "Antenna" that pick all and any spurious external electrmagnetic fields ( cue ignition system in perhaps this case ), oh... now we need to provide a "shielding" configuration and behold the three probe/"grounding" lead test probes... this is getting silly.. Modern test equipment will have pluses and minus in measuring application and techniques, it is not a simple, the device is accurate and is a true and meaningful reading, much is application and interpretation of the measured result. To call it Complex would be a simplification in the extreme.
Most notable, the verifiable CMRR of the modern testing device(s), for the broad device types in Shindengen;

J from a big local Rockabilly festival, had my Jota next to the stage, post band last number, fired up the Laverda, had the punters jumping out of their jeans or dress, sound was a very good encore... plenty of bloke grins amongst the classic car mob... stamping your place in the arena.
