My TDM 850 did the same. I just got off the first time it stopped. Lovely bikes though if you think the AT's brakes are hard work to maintain you ain't seen nothing yet! The worst bit is that it's an absolute ******* to check the oil level. Even in broad daylight you'll need a torch and both hands if you don't have a main stand. And you can't not do it regularly as they do use oil. Excellent commuter though and very good fuel consumption.
