I'd say BMW 1200GSA, if only to satisfy my sense of proportion

That is a massive bike.
I'd go for the latest Z1000
The Z is at the top of the list. I haven't sat on one yet though. I did sit on the previous Z and liked it a lot.
The KTM 990 Adventure may be out though...that bike is friggin' tall!
I do like the KTMs, but they are all really tall it seems.
