Is there an electronic wizard able to explain why, if a lithium-iron battery is able to cope with being charged by a motorcycle’s electrical system, it requires a special mains charger?
 
Correct me if I am wrong but AFAIK, the main problem is a mains charger with a "recondition" function which "pulse" charges at 16 volts.
This is too high for a lithium battery and will cause overheating and possible fire.
Most bike lithium batteries have an inbuilt Voltage (or charge) Regulator to drop the bikes output down from 14+ volts to 13.2 or something like that which is ideal for lithium batteries.
To the best of my knowledge, a standard (non multi-stage) old fashioned battery charger should be fine if the lithium battery has an inbuilt regulator.
I believe that even the inbuilt regulators in the lithium batteries cannot handle the "recondition" function.

I also believe it is the smart chargers that are the problem. Not an old school charger.
Most people these days use the smart chargers.

They make lithium ion powersports batteries specifically for using in motorcycles, so I would hope they can survive a bikes's charging system, otherwise they'd be useless.
 
I have a Litium Battery on my bike and there's no problem with the bike's charging system. Don't use a modern smart charger as the "Sulphate mode" will destroy the battery. Just use a real old fashioned charger or one where you can turn off the "Smart charging".
