I'm kinda surprised to see some posts on this thread bashing bmw reliability. I thought that was one of the things their famed for... they are the only ones that give a 3 year warranty, afaik. Others are 1.
I've had a f650gs for a few years now that I bought used and it's never been in the shop. I've put on a new chain, gotten new rubber and done countless oil changes and that's been it. It's been abused and it's been bulletproof.
I was thinking of a wee but was surprised at what used ones were going for locally. When I realized the msrp was the same it's got me thinking of the 650 twin. The wee has a track record but the beemer is about 30 pounds lighter, makes a bit more power and a lot more torque. Pretty compelling in my books.
