Gas

Before my motorcycle I owned an Audi A4 that was pretty good on gas. in a month I would spend about 70 dollars on gas.
Now, 70 dollars can buy enough gas for 7 months to ride my motorcycle. not only financially, there are many benefits for having a bike.
Compared to an SUV that emits 205 grams of Co2 per kilometer, a motorcycle like the one I have only emits about 100 grams, it is half of what a car produces car.
The average mileage I get on my motorcycle per gallon is 70 miles compared to a car that usually does 25 miles a gallon.
