Have had / got a few of these for the charity...
Pan - superbly capable, reliable, comfortable, handles well, great weather protection, strong motor. But doesn't stir the soul at all.
Fjr - rocket ship, definitely the sportiest of the ones I talk about here. Engine is blinding, riding position more forward than the others. Worst weather protection (and probably least pillion comfort). For the flagship model, suffers dreadfully with corrosion ( including on top of the motor, where you can't see it, and the rear suspension linkages wear fast if not stripped and greased each service).
RT - avoid like the foccing plague! Comfy, great weather protection, but ours had so many electrical failures, recalls etc etc, I lost all confidence...
One not on your list, triumph trophy. Great weather protection, comfy, unsure so far on longevity. Dead easy to ride, fast or slow, but does weigh a ton, and you can tell in the twisties. The weight is low though, it's easy and confidence inspiring when slow control is needed (unlike the RT!) Engine is grand, gearbox ok, unsure about the final drive. Have heard from a few folk that have had to have theirs replaced.
