Ouch! That's a bit of a mess. Could easily have been caused by high resistance due to dirty contacts.

Or from it being jumped several times from an Audi with engine running

to melt that connector there must have been some serious voltage going through it. so you have a fault elsewhere. or the connecting terminal is furred up causing arcing.

After braking down roadside we tried a lot of times jumping the terminals at the starter. Sure that would be enough to melt it?

doubt it. unless you had the car running.

i personally think its been fried before jumping the bike from the car and thats why it broke down.

There's never a need to have a car running if jumping a Motorcycle and as you've found out it can ruin components on the Motorcycle.If the extra passive power from the larger Car battery won't start the machine then starting the Donor car won't help.The fault on the Motorcycle needs to be fixed.

Because the internal resistance of the Motorcycle battery will be lower than the Donor battery as it has been depleted the extra current from the Alternator on the car will bypass it's own battery and shunt the current to the smaller and much less robust Motorcycle battery.The danger to the Motorcycle electrics will increase further if the Donor car is revved up

i'll stick my neck out here and say what i think has happened. i'll take a wild guess and say that the burnt out terminal is the red wire. now since the bike had a fault and broke down i'll say that the terminal was already on its way out. the reason for this is that the regulator in the RR is passing too much voltage or the rectification is collapsing and letting AC through, this is really bad news as the AC is at much higher amps. wiring, connectors and fuses dont care if its AC or DC but the terminals in connectors are specified to certain amperage be it AC or DC when the terminals go over their specified amps then they either melt, explode or in this case heat up causing the plastic around it to melt.
