This will be a "fun" ride motorcycle also not just for commuting. 8)
Assuming that the commute is mostly a steady state 55-65 you can expect at least 55 mpg.
Depending on how much "fun" you have you can approach 40 mpg.
My Savage replaces my wife's (she's owned it longer than she's owned me) 1972 Camaro RS 350 LT1. The way I drive and as bad as it is running I am saving over $.25
per mile.
Assuming 60 mpg Savage replacing a 20 mpg car on a 80 mile round trip commute regular gas at $2.60 /gallon you are looking at $45 week in gasoline savings -- $195/month, $2250/year.
Toss in the depreciation of 20,000 miles/year on the cage vs. the bike. and you're looking to save another $2K a year.
With the Savage you can do most of the maintenance yourself for more savings over a cage.
You also can arrive home relaxed and ready to tackle a couple of jobs around the house versus arriving home after frustrated from fighting traffic in the cage and needing a double scotch.
