about 30 dollars a mile on average
I'm not sure where the original poster got his $30/mile figure from, but in truth the $$/mile rate is so wide that an average probably isn't what you're looking for. An inexpensive, easy to fix bike bought used for 1/2 it's MSRP with only a few thousand miles on it might come out to be about 40 cents per mile after 20,000 miles. A nice Harley could run over $1.50 a mile. High performance bikes can be even higher. A 20 year-old junker could cost more/less than a slightly used bike after 20k miles (based on luck/make/parts) but likely never less than 35 cents per mile.
If you get something very solid, like a shaft drive BMW and you take REALLY good care of it, you might be able to ride it for 60k-200k miles, (Honda goldwings and some others can last forever as well) but very few people use bikes in such a way as to let them live so long. If you're one of those people, your operational costs will be trivial.
Insurance costs are interesting. As a guy in my early 20's, a month of bike insurance was about 1/6th the cost of car insurance. At 30, it's still lower, but not by much.
From Capsar:
I once had much the same question. That was 40+ years ago. As stated so well above, your cost is relivant to cash outllay. Not staying within your criteria will dramaticly lower any cost savings you may have garnered. a general rule of thumb is what the monthly payment is + 1/3 the cost of travel by auto for a small/mid size bike to 1/2 the cost for a bike big enough to run the freeways. A full size cruser is usualy near break even. Go biger such as a trike or dresser and you have a luxury item where savings are not enough to count against the expence. Factors as to how you ride and what type of bike you need are also major concerns. As always... a loose nut on too much horsepower is never cost effective.
The average cost per mile to operate a motorcycle is dependent upon the type of motorcycle. The average motorcycle will cost one third less than the average automobile.

The cost per mile for a garbage truck varies somewhat with the price of diesel fuel and the age and condition of the truck. On average, the fuel cost per mile for a garbage truck is about $1.33 if diesel fuel is selling for $3.99 per gallon. The trucks generally average 3 miles per gallon of fuel.

The average cost of bulk transport varies, but it usually is three dollars and once cent per mile for the cost.
The average cost per mile doesn't care about where you're driving, it's only concerned with the gas mileage of the vehicle, and price per gallon of the fuel. Figure out your gas mileage, check the fuel prices, do the math, and you're done. gas price/MPG=cost per mile
To determine the average cost per mile for a 34 passenger bus with a 7.3L diesel engine, you would need to consider the current fuel price and the bus's fuel efficiency in miles per gallon (mpg). Calculate the cost of fuel to travel one mile by dividing the cost of a gallon of diesel by the bus's mpg. This calculation will give you an estimate of the average cost per mile based on fuel consumption.
The average cost for motorcycle insurance varies based on age, driving record, location of residence, type of motorcycle, and type of coverage. The price can range from $200 to $1000 per year.
A motorcycle may cost more than a car to maintain. The average cost of the oil change is $50. Tires cost about $125 or less each. When considering motorcycle maintenance, there is storage fees ($50 a month) to consider if the motorcycle is to be kept in a snowy climate in winter. Each year the motorcycle should also have a tune up before taking it out on the road ($125).Total average maintenance per year $500 or more.
One straightforward way to calucate auto cost per mile (if your only taking fuel consumption into account) is: Price per gallon of fuel divided by the vehicle's average Miles per Gallon. e.g., $3.80 per gallon / 22MPG = 0.172727 per mile therefore, it would cost $ 0.173 per mile or 17.3 cents per mile. Other factors such as vehicle deprecation, tolls, oil use, insurance also should be considered in account but would complicate the equation.
