Regarding overfilling, on one of the TDM850s (also Dry sump but with an external tank) it was poossible to split the tank due to pressurization if it was overfilled. The Super Tenere has its storage inside the engine cases (thats what I understand anyway), so no idea what effect it might have.
Re oil use I had an '84 XJ900 Yam, it burned oil when ridden hard but never used much when used for commuting, a '91 TDM850 (iron sleeves) burned some oil it's whole life, '02 TDM900 (coated bores) - never used a drop; I expect the 1200 will be much the same. I'm old school with the synth changeover, would rather get some miles on the motor before considering it. My R1100 used to just ooze oil out of the motor when running synthetic so she went back to mineral oil and never leaked again.
