Not enough miles!!!  Got in over 8000 in 2010 starting at the end of May when I bought the bike.  Also, we wound up cancelling too many of our overnight trips.  That dang work stuff just got in the way this year.

Tires:  Installed a pair of Conti Motion tires at 8880 miles at a cost of $168
Replaced the rear on 4/2/11 at 14180 miles and the front on 6/1/11 at 15743 miles with Michelin Pilot Road 1's at a cost of $200
The Contis lasted 5300 rear and 6800 front.  The Michelins currently have 5800 rear and 4200 front with tread on both.

If a pair of tires costs $200 and lasts on average 6000 miles, that works out to $0.033 per mile.  Not bad.  I used to figure $0.04 per mile for tires on the Suzuki but that included paying a dealer to install them.

8/12/2011 at 17731 miles installed a new Deka ETX-14 12 Ah battery for $48.  I am not sure I actually needed the new battery.  I think my starting problem that left me stranded that day is actually related to the side stand interlock switch, not a weak battery.  It still happens intermittently.  So far raising the side stand has always allowed me to start the bike.

If we just assume a new battery every three years and 6000 to 8000 miles per year, that works out to $0.002 to $0.0027 per mile, assuming we can continue to get inexpensive 2nds at the Deka plant in Lyons.

I am paying $156 per year for insurance which works out to $0.026 per mile.

The BMW required maintenance every 6000 miles, typically costing $400 which works out to $0.067 per mile.

OK, so gas, tires, maintenance, insurance, batteries add up to $0.214 per mile.  If the $10,000 bike can go 100K miles without major repairs, that's another $0.10 per mile, so call it $0.32 per mile plus gear plus entertainment tax if you're not careful.
