The Blackbird is a big bike for the city. It drinks petrol and is expensive. I love it, but I'm considering the possibility of a second bike for commuting. But what? I want it to be reasonably cheap and durable. Relatively narrow (for lane splitting). I don't want it as underpowered as a 250, so about a 500 or 600cc would be about right. I would want it to be unfaired, since fairings just add to the cost, particularly in an accident. I do want it to be kind of cool though. I'm thinking cafe racer-like. But what bikes fit this sort of description these days or in the not so distant past? Absolute max cost about $5k (second hand of course), but preferably less. Any ideas?
