I could be interesting to see a detail cost analysis, lots of folks spend lots of money in accessories but that's a choice, then there is the initial cost for the gear (which is not there for a vehicle) and the high insurance cost but these two decrease over the years, but it also has a low operating cost (fuel economy, and low maintenance cost) the initial purchase cost is cheaper for a motorcycle plus the depreciation is less compare to a car. Honestly I think its cheaper to run a motorcycle then a car... way less practical but cheaper if you compare the two.
