I think it was the 800, it's all about seating position and the adventure bike seemed to fit me better than the 1600. I also have a lot more experience on sport tours now and that probably factors into it. I'm by far more comfortable in an more upright position vs a more aggressive forward lean. I still struggle with my legs being under and behind vs stretched out infront of me.

Either way BMW makes a phenomenal bike and I would love to add the right one to my stable...even tho my GF was trying to compare bike to shoes and saying you couldn't have to many I think she might balk at a 4th one at the moment
