PROS: Usually a faster commute time, ability to use the HOV car-pool lane. Better gas mileage and lower maintenance costs. Easier to park, many parking garages don't charge for motorcycles as long as you don't park in an auto space. Riding a motorcycle teaches you good defensive driving techniques - promise you will take the motorcycle training class!!! Don't be "one of those motorycle riders" - be respectful when you ride.
CONS: Cagers and their idiotic motorcycle blindness, i.e. Death.
