Most of us who have used Odyssey batteries have had EXCELLENT results with them. And you are right, they hold charge MUCH longer than standard "wet" lead acid batteries.
If you have a multimeter than can measure milliamps available, disconnect one battery lead (safest to do the negative one) and measure the current flowing with the ignition off. It should be only a few milliamps. There are small drains on the battery even with the ignition off, such as the alarm system, clock, etc., but these are very low.
You did not by chance turn the igniton all the way to the left into the "P" position did you? That would be very noticeable though, as that leaves the center tail light and little park bulb in the headlight on.
As I have said before, I have an old Odyssey I took out of the bike before a long trip, it sat on my garage floor for MONTHS, but still started my lawn tractor easily when the tractor's battery died completely. It is still in the tractor, never charged (except when the engine is running), and starts the tractor readily every 3-4 weeks when I need to use it. That battery had been used in the LT for about 3 years, thought it was losing capacity, later found I had an alternator issue (charge indicator light connection) which was causing my bike to sometimes charge, other times not.
You definitely either got a bad battery to start with, or there is something draining it.
