The BMW would have to be an awesome tourer, I'm thinking for my next bike go for something more like that (less sports and more touring). Yeah you'd think the wife would love the maths, but, I'm starting to suspect she doesn't like bikes (at least me having one), there's always something that comes up that ends up with me not getting a bike. I think the only option is to go behind her back and tell her about it after the fact. That's going to be a fun conversation.
