Makes senseI never stated that I commute on the bike to save money...certainly, that's not the reason. Like, today: It's going to storm. I have a better vision of the road on the bike than however fast my wipers can wipe in a car. It floods quite a bit around here, and I can ford deeper with my bike. It's fast, highly maneuverable, etc., etc.
The initial poster was talking about gas mileage. I was responding to how another poster assumed that people used motorcycles as, perhaps, a toy, or hobby. While that may be true for most, that's not why the rest of the world uses motorcycles.
But, all for all: yes, it's not cheap to own and maintain a modern BMW, especially as compared to my old airhead. However, for bang for the buck, and the fact that I can commute all year 'round here in Virginia, then it is a very useful tool and, over time, it works out. My last beemer, a CLC clocked 86,000 miles, of which about 80,000 miles was commuting, before it got totalled in a rear-end collision. While the RT or CLC probably is not considered a commuter, they have served well in this capacity.
